How Helldivers 2 Async Compute Setting Effects FPS 

Could you explain it for dummies pls? 🙃

@@adrianbyg5553 Imagine you're at McDonald's. As a normal person, you would eat the fries first, BigMac second and sometimes stopping for a drink. Now if you turn on Async Compute/Eating, you would eat/drink all three of those components at the same time (meaning you smash all of them down your throat), thus finishing the meal faster.

@indreknurja9312 ohh... and that would make it harder for the CPU, but if the CPU is a strong one, then the pc will do things faster I thought this was already happening with the multicore CPUs

I think so

Haha yeah maybe. Turning it on essentially places more load on the CPU by the looks of it or utilizes less of the GPU. Now maybe that extra CPU utilization is doing something I can't measure or see like some are saying it could be helping with latency. The options description present it as helping performance with some systems and with my pool of hardware I chose for this video it didn't really help turning it on.

@@TerraWare You can enable a frametime graph with F4 and F2, for me enabling async put more load on the GPU (the green line), which is the bottleneck so it reduced my FPS.

Thank you for saying this, needed the laugh lol

Wow. I just read this comment, the borderless window does make a huge difference and i appreciate adding in the note about fullscreen with DX12.

Ryzen 7600X is a very good gaming CPU, a very good pair for 7900XT. I did a build for a friend of mine. Ryzen 7700X and 7900XT. It came out great. In gaming 7600X and 7700X are pretty close.

Thanks.

Oh yeah. I have mentioned this in another one of my videos. I have made quite a few looking at HD2 in the past.

Ok that is actually interesting. Maybe it helps in crippling intensive scenarios which some have mentioned. I tried to present some firefights but in this game each mission or firefight can be so different from one another that it can make it difficult to compare and come up with a meaningful measurable difference. Basically I ended up with sometimes Async on having slightly higher fps with firefights and sometimes slightly lower because of how random everything is.

Huh, then having an old gaming laptop that barely passes the minimum required hardware, maybe I should consider the option since my fps often slows to a crawl when there are hundreds of enemies on the map or when multiple bombs explode at the same time.

It's all good my friend. Thanks for stopping by I appreciate it.

I didn’t even know there was an Autodesk game engine

Lol

5900X is a pretty good gaming CPU. I have my 7900XTX paired with the 5900X, it's my living room pc.

@@lukemehalick370 Radeon cards have less driver overhead. When cpu limited radeon cards are often faster than nvidia, and these cards are so fast being cpu bound happens at 1440p and even 4k with a 5900x. Also funny that the 7900xtx has 95% of the 4090 in this game, which is one of the better looking games to come out this year.

Most people don’t know about this

Not that I can see. I would recommend keeping it off.

I hear you and those would be CPU intensive calculations. Problem is you cant really replicate an identical scenario as a 1 to 1 to compare and get accurate results. In one fight you may get two ranged automatons, one big one and 3 melee ones and another they can call in a reinforncement ship. My angle of setting it up was to present a CPU and GPU bound scenario for all combinations that bottlenecks consistently than see how Async compute effects things. I tried engaging into battles and I was running into results that were kind of allover the place and hard to come to a conclusion that I could present.

@@TerraWare yeah that is fair, and it would be nearly impossible to test it correctly if this is the case. Especially to trigger a bottleneck situation would need a helldive engage with big patrols, that will never be replicable

@@TheShadow6391 I don't know I may try something. One way I can do it is solo. Basically choose a mission and land on same spot. Attack an objective clear it and than exit the game without returning to ship. This allows you to go to that same exact mission when you relaunch the game. I have got one comment from someone with older hardware saying async compute on lowers their overall fps a bit but their 1% lows are better so there could be something to this.

Yeah exactly. Even the same mission can have slightly different outcomes depending on difficulty, type of mission and other factors. It's why I tried to test standing still that way I could have an exactly the same 1 to 1 comparison.

Totally, my average fps drops like 15 percent on the really verdant, foresty planets

OK that's cool. It's why I wanted to ad a very slow CPU like a Ryzen 2600 than pair with a powerful GPU but I didn't really see much of a difference. I would like to find a way to check in intense combat, only problem is the randomness of the game and how different each encounter can be to duplicate a scenario. I have a theory in mind I could try but I did try to include firefights and the results were inconsistent because of the randomness of the game.

I noticed that too and am not sure why. For example its not happening with the XTX in the 7800X 3D part of the video and it didnt even happen with the old 5900X footage I recorded 3 days ago but it wasnt good enough I had to re record it so I did that yesterday and thats when I noticed the little hitches with the 5900X and 2600. Am not sure if it's a new Helldivers update? I used just a C1 OLED tv for all these recordings, same display, only one no multiple.

@@TerraWare I've had this issue since the first 24.x.x driver up until the pre-last one. During that time I was forced to stay on 23.12.1,but now with the latest drivers that fix worked for me,just switching the monitors off/on, maybe try having the entire pc off even for a bit. I believe the issue is somehow related to the idle power usage where certain monitor configs won't allow the vram to downclock from 900mhz causing over 100w idle power usage.

@@vyathaen I will have to look into it. Maybe see if it happens in other games. 24.4.1 has been pretty good for me so far.

Dual monitors have been an issue since launch causing high idle power. No idea why but the they did mostly fix the idle power.

@@quintrapnell3605 not for me, had to adjust blanking rate via cru

The data at the top includes 1% lows

That's why I used a Ryzen 2600 cpu with a 7900XTX GPU. Now I do have an even older CPU a 6 core AMD FX but didn't bother with it. Would need to put a build together for it. Ryzen 2600 is below the recommended though.

I personally use afterburner but when I have compared both the AMD overlay and Nvidia they tend to the same as afterburner. Are you showing both at the same time and getting different results?

@@TerraWare yeah i used them both at the same time. I also but all of my cores on display with msi afterburner and noticed that the default “cpu usage” showd atleast 20-30% difference in usage. But I saw that my “cpu usage 5” was at a similar usage. So yeah i dont know what software to use. A friend recommended some kind of nvidia and intel sofware that i haven’t tried yet. When i have tabbed out of the game then it usually shows 100% cpu usage on task manager so I think that msi afterburner is showing wrong usage %.

@@toomas415 Theres Intel presentmon. Than there's also HWinfo which goes into super detail and tends to be accurate. Question have you updated your motherboard bios at all? I ask because I wad a very early adopter of AM5 with a Ryzen 7700X and back than I couldn't even read CPU usage and a lot of stats wouldn't even show until months later after bios updates everything got to normal. I would personally expect the AMD software to be accurate. Also I assume you have installed chipset drivers and all that.

@@TerraWare yeah recently updated bios and i have installed the latest chipset drivers.

@@TerraWare I think that the amd software is correct on its gpu/cpu usages because I dont get constant 100% cpu usage on any other game besides Helldivers. Iv tryed so many fixes to limit the power of my cpu but it just makes things worse. I tried to search how to put my cpu on eco mode but I haven’t found a clear answer. I do not know what spesific ppt tdc edc values i need to put in for my cpu ryzen 5 7600 to use eco mode. I know that in previous bios updates there was a button to enable eco mode but it doesn’t exist anymore.

GPU's yes. I have some weaker GPU's like a 6800XT/3080Ti and RX 580. Since Async Compute is a GPU function though I wanted to bring the best and than present 3 different CPU's from fastest to slow. I thought of maybe adding the RX 580, maybe I should have.

I hope so although they've already delisted the game in like 170 countries where PSN isn't available. What a dumb move.

my Guess is Gabe doesn't want to be in the legal battle when Sony deactivates all those games after taking everyone's money.@@TerraWare I assume both sides can revert this.

@@quintrapnell3605 Sony hasn't really been known to revert decisions as far as I'm aware and the fact they've now delisted the game in all these countries tells me this decision is here to stay, which if it does they will HAVE to refund the people who can no longer play the game obviously. With time the game will bounce back although it will lose some of it's player base unfortunately and it's flawless perception will be tainted but I still feel it will continue to be a success because it is a good game and that's usually what's most important.

@@TerraWare if Steam delisted the game however is what I am saying.

@@quintrapnell3605 And I get some Sony fanboys saying Sony will and should bring their own launcher to PC because they shouldn't have to share 30% with Valve. Sony can't even sell their games to the whole planet and their own launcher would be a massive hit to their sales. Another road block. They should've left this game alone and let the people enjoy it. It makes me kinda mad because I like this game. I have family in one of the countries that will lose access to this game.

I've been playing with presentmon a bit and trying to figure out ways to integrate it somehow. I hate you cant move the window where you want although its come a long way. It makes perfect sense that CPU busy would increase with Async On based of my results. Yeah that would've been a good little extra to ad into this video.

Yeah I guess that makes sense.

That seems extremely unusual. You sure maybe the new driver reset your graphics settings somehow? Thats an insane difference in performance driver to driver.

@TerraWare my settings were the exact same. That's why I rolled back my driver, after watching Gamers Nexus video series about drivers and how they work, that's the best situation I can assume was the cause, after rolling back my driver, I'm back to around 63-81fps. I play in 1440p Native but my settings definitely haven't changed, so I found it weird myself tbh. I have noticed while some drivers get updated for new games, it can break other games due to the way drivers are built and optimized. But then again maybe I just got unlucky lol

@@XxFusionsk8rxX So you are GPU bound than at native 1440 with a 3070. I may have to look into this.

@TerraWare that could very well be a big possibility tbh. I'm only 5yrs deep into being on PC, this is my second build so, I'm not a genius, but I definitely love learning. I'll give a sub and I'd love to see you post a video or something similar regarding this!

@@XxFusionsk8rxX Thanks I appreciate it. I've a 3080Ti I can look at when I get a chance.

It makes sense because the ship is not as GPU intensive as the reset of the game so it's where you would notice it the most. My conclusion was it ads more of a load on the CPU while making GPU less busy having it enabled. I recommend keeping it off. In a GPU bound scenario it didnt make much of a difference either way.

@@TerraWare On the planet I lose on average around 15 fps when I turn it on, but since a few updates I have the feeling that it has become significantly more CPU intensive because I get stuck in CPU bound more often than before. A month ago I was avg at 100-110fps on planets and was always in GPU bound and now mostly 80-95fps and often in CPU bound. In the ship I had around 190 fps on 1440p with resolution scale on ultra quality and 220 fps on quality and now a maximum of 170 fps on quality. I only play on native anyway, but even on native I'm often CPU bound.Let's see what happens in future updates. In the meantime, I'll continue to follow your videos.

Yes very unfortunate about the PSN. They delisted the game in like 170 countries (where PSN is not available) this is awful. I have had a PSN linked to my Steam for more than a year btw. They give you unique skins in Spiderman, Ratchet and Clank, Sackboy. It's what I feel they should've done in Helldivers. Keep PSN optional and incentivize players to sign up by giving them in game credits or unique skin. I hate seeing this happening to HD2 its a good game with a passionate team and community.

@@TerraWare Yeah, at first I thought people just didn't want to sign up to PSN, then I saw that PSN isn't available in that many countries and it made no sense. They completely delisted the game from all those countries, It's just hard to understand the thinking. Why would you want less people playing your game.

@@XDDX_NZ I've been following this and the CEO of Arrowhead said on Twitter earlier that he wasn't completely faultless in all this. Basically Sony told them 6 months before the game launched to implement the PSN requirement in the game because Sony wants PSN to be integrated for their online games, which I can understand since many companies do this for live service and online games. Ghost of Tsushima for ex will require a PSN account for its online component but not offline single player campaign. Come release day this account was required for the first two hours after launch apparently and the game got so slammed the CEO made the decision to drop the requirement to take the load of their servers and apparently said they would be adding the requirement in the future. He was confronted about why the game was allowed to be sold to people where PSN wasnt available and he said he didnt know PSN was restricted this way. I like the CEO he seems like a good guy but he is right he's not completely faultless in this case. Still makes me wonder though how popular the game would be today if that PSN account was a requirement from day one.

@@TerraWare Just saw that the PSN account linking update is not happening anymore, so it looks like Sony finally listened to the feedback and hopefully it will be the same for their future games. Good news in the end but if they already delisted the game from so many countries and steam has given refunds to some people, then they have already done quite a bit of damage in a few days.

@@XDDX_NZ Yeah I saw. I'm certain moving forward they will require a PSN for other games with MP. It already does for GoT multiplayer. I guess it makes sense they want to unify their games and for what its worth Sony games have been pretty good on PC. For example HFW and GoT are DRM free games, they sometimes go out of their way to include PC specific features like FG or extra ray tracing features.

What processor and resolution do you play?

@@TerraWare Ryzen 9 5900x I play 1440p

@@HeresGrey That seems like quite the drop. I did a video last week with same setup 5900X/6800XT at 1440P. I have never seen drops that low but than again I havent done any of the very difficult missions. Check out my video though and see if those numbers reflect yours. I think they should.

It shouldn't really matter I believe that's just a hard limit. If you set it to 100% it doesnt mean it will always run at 100% but will go that high if needed. I'd just leave it at default unless you are overclocking the card than maybe set it to 100%

Ikr?

Having it off or on?

@@TerraWare on + directx 11 + upcaler + very low settings

They do correlate in some cases

Like it doesn't help that different sources are using different language when describing the setting. Most I see describe async compute as a means to "improve efficiency."

And that's why the recommendation is to use it with weaker processesors, so that one core or thread doesn't get overwhelmed with work if the gpu can process some tasks concurrently with async enabled.

TLDR, if you prefer fps turn it off. If you value better input at the cost of some fps, turning it on may improve efficiency.

I don't know about the latency. I'm not equipped to measure that. Maybe it does but the settings description of the setting says it can help or hurt performance depending on hardware configuration which is why I wanted to test a range of hardware focusing mostly on different generations of CPU's I have.

It's kinda true. i limit it with external means (Radeon adrenaline, or rivatuner) instead. same cap at 60fps, my cpu usage down about 20%. it's ridiculous

I've noticed frame limiters are not properly implemented in many games. A recent one is Dragons Dogma 2. For me using RTSS framerate cap seems to produce the most consistent results. It's what I personally use although you can use the built in framerate limiters in Nvidia and Radeon driver software.

I've found that switching "Display Mode" from "Borderless Window" to "Fullscreen" seems to enable the frame limiter, Freesync (and vsync). It shouldn't work this way, but seems to anyway.

Another person in the comments section with a 3070 said said they saw a drop in fps with the latest Nvidia driver they said they rolled back to the previous version. Not sure I haven't looked into it. I dont have a 3070 only a 3080Ti

Nôt gonna thrture my eyes with that mess rn. I hope you have great Day also nice video.

For communism . lol #joke

Turn it on if you want to sync in a refund I guess.

"a sync compute turned on in this game is only good if your gpu is better than your cpu wich usually is the case for older computers" That was my thinking for this setting being there which is why I threw in a Ryzen 2600 at 13:20 with a 7900XTX as a gpu. A very unlikely combo and FPS was very slightly higher with it off. Testing it in a firefight would be something I'd like to be able to do only problem is this game is very random and procedurally generated to produce a consistent scenario for exhibit AC ON and exhibit AC OFF if that makes sense.

@@TerraWare it was a good test , but in simulation processing power the 2600 is still a little better in processing than the 7900xtx apparently xD just shows the difference in data processing tasks can influence fps a lot gpu cores really be having a hard time with simulations like this

I tried firefights. The problem is as you probably know that it's impossible to try to present an identical scenario twice to compare differences because in one engagement you may get 10 automatons made of a few troopers commissars and a berserker. In another there could be twice as many and they call a dropship. We are talking margin of 10 to 15% so I was getting conflicting results to present. Instead what I tried to do which I explain is present a CPU and GPU bound scenario for all hardware configurations. The point wasnt to see the capabilities of my CPU's and GPU's in FPS but how Async Compute effects FPS in different hardware.

Don't have one unfortunately.
