Helldivers 2 - Is DX11 Better on AMD RX 7900XTX? The Good, Bad and Tutorial 

just was looking for this kind of comparison, thank you!

Changing to dx11 completely fixed the crashing for me and I get better frames. At 4k, I only have that slow motion problem at the very start of a game when my hellpod is dropping but then it returns to normal before I hit the ground. I have a video if you want to skim through it and see.

ty, sir! you saved my poor 1050 ti :D

Damn man, yesterday i bought the game. I was unsatisfied with the performance at first and found a reddit thread about DX11... Didn't expect the performance gain to be this huge but it was, then youtube recommended this video. Crazy stuff

Omg thanks broo!!

Thank you for the video. I'm trying to squeeze as much out of my 3060 Ti as possible. At 4K, I get noticeable improvements but it doesn't feel as stable as 1440p as you're showing. I lose HDR, but before I saved15% GPU utilization at High settings, with +Ultra Quality scaling. This is definitely worth doing if one is going to choose 1440p.

DX11 is capable of using multiple threads, in fact it can use upwards to 16 threads. BUT it requires a lot of work to get working properly, the API actually has tools that can automate this but doing it manually is better. DX12 is easier as it falls back to driver level optimisations and allows the GPU schedulers to properly balance the thread the workload. This is why if you look on 1440p DX11 you get higher CPU usage than on DX12. This is because the API is trying to automate the threading whereas on DX12 its using around 10-15% less CPU usage but the workload is being better spread out across the threads of the CPU. Fun fact, Vulkan API has the ability to scale upwards of 64 thread limit, DX12 at the moment is 32. Basically anything passed 16 and more manual work is required but its easier than on DX11.

I checked and there is no problem with 4k on my 7900XTX + 5800X3d configuration. Everything works correctly. Performance increase similar to 1440p approximately 30%. Currently there is no reason to play on DX12. I don't see any difference in the graphics. Thanks for this video.

I've wanted to be able to use DX11 to see if it was what happened to me, because my frames from the first month of release are gone. It seems that we can't use DX11 anymore, they blocked it from working somehow, i could not even get to the launch screen. :/

Huge gains at 1440p. Great job looking at this, surprised the difference is that big at 1440p. Might help out some people with lower end GPU's since this game seems so heavy. The 4k slow mo footage looked so cinematic with this game's animations lol.

I have 5800x3D and 7900XT, and even on 4k, the fps boost is massive, no slow-mo glitch at all.

In curious I’m getting great performance in forbidden west im curious to know if is possible to use directx 11 since horizon forbidden west use directx agility sdk

The difference is huge!

nice I have the same card. I had to toggle the bios switch to the lower power profile because the game was so unstable.

Nice! I did not know it was something you could do. I will stick with DX12 tho. Oddly my Reference model 7900XT at 1440P Ultra setting with Native 1440P is averaging 80 fps. In combat in a team I see about 70 fps. Not too far off the 7900XTX it seems.

Hmm will give this a try. Maybe it can help with the current CPU overheating problem in hd2.

Using ultrawide 3440 x 1440 and getting about little over 90 fps max setting with the 7900xtx on DX12 (With 7950x but still able to utilize +95% gpu).

I run a 5800X3D with 7900XTX At 4k DX12 all max Settings I get an average of 84fps...wh, do you get so much lower numbers?

I was playing DX11 4k native since the launch, since it was working for me on my 7900xtx, and I forgot to change. In the latest month, I got slow intro, ctrl issues and it was lagging a lot on the land. In the DX12 the issues disappeared. I didn't experienced the slow mo during my DX11 plays

Are you having crashing issues with your 7900XTX Saphire? My game is constanting crashing with 15 minutes of playtime. Not sure what is the problem and even running it in DX11 doesnt save it

This just helpe alot of older rigs, Democracy thanks you!

I see no issues here. Democracy always comes in slow motion. Ask North Korea😄 Joking aside that was really interesting to watch! I'd never imagine the difference would be this huge, good stuff man!

Tested this on my new steam deck, while I suck at the game and stay on the lower levels, I can hit my frame cap of 40 with little stutter, res scaling set to quality and most settings low with high render distance

i have RX6800 and ryzen 7 5700x 32gb 3600mhz ram and game crash on start wen i try DX11

bro dx 11 fixed my stutters when there are stratagems explosions there are no micro screen freezes anymore i still get insanely low fps 32-40 normaly and 13-18 on explosions or when there is a lot of bugs thx to my 2012 dogsh1t cpu but its way way better now.

Just tried this and it definitely works a lot better at 1080p, went from 90-100fps on planet to 140+. At 4k I doubled my frames from 40 to 83 but i also get the slomo effect. DX12 has weird CPU usage and 11 def feels like it uses CPU cores better. Edit: I have a 5800x3d and a 4070ti

Should dx11 be used with an nvidiq bases gpu?

Did you notice a visual difference between dx11 and dx12? I remember playing some games that looked better in dx12.

If I want to change it back at some point I can i just do the same command just with d3d12 instead?

Seems like its still possible to load in DX11, Launch the game with the command and without the file, a black screen will pop, but wait, should take a minute maybe to generate new shaders and then the game works !! But dont expect a miraculous improvement in performance.

dx11 dont have access to async compute but if the dev dont have skill to utilize it, it will not different also dx12 is multi threaded not single threaded api like dx11 so it will not get huge steep fps drop as dx11 when in heavy scene, this is normal not thing strange

Dunno my sapphire 7900 xtx with same CPU dropping on the heavy fights to 70-65 FPS by some reason 1440P ultra graphs maybe I have wrong settings or ?

Difference is indeed huge! Currently running R7 7500x + 7800xt. There *shouldnt* be a massive bottleneck, however my CPU is using 100%, whilst my GOU is using 70-80. Changing to DX11 tomorrow, lets see. If this doesn’t work, just bad optimization I suppose?

Why is my 7900 XT only using 60% usage, and why do I get low fps stutters?

--use-d3d11 the game just opens black screen and closes... any help?

I cant play on DX12 on my 7900 XTX.. even with new drivers. I have to use DX11 to get no crashes. Its so sad.. DX11 works fine but no standard DX12. and we talking about a 7900 Card......

Doesn't seem to do anything for me with a 4090/ 12900k. Guess this is an amd thing? My fps isn't bad per say, think most of my fps loss is just in the fact that I'm cpu bound.

7900xtx at 1440 native only getting around 100fps? my rtx4070 is doing this. wtf?? Is this game CPU heavy? I'm also using the 7800x3d which seems to be what's driving this game.

my game crash when i try launch with the comands dx11

I have a RX 6700XT, by doing this, it increases my FPS but the 1% lows are lower than using DX12, so it feels sluggish to play with :(

Not only FPS but frametimes look better

How are you not having frequent driver timeouts using the 7900xtx? I can barely sy the game.

It's odd I'm not having any issues with DX11 at 4K on an RX 7900 XTX & R5 5600X What I do see however is 100FPS compared to 70FPS with DX12 now let's hope the crashes are fixed by this

nice video bro, tried on my 4090 and game wouldn't even load pass the black screen lol frame time was over 1000 m.s gpu usage at 0-3% xD

rtx 4070 ti and ryzen 7950x3D amazing boost fps

you can make these gains with a simple UV/OV

Does anyone else have crashes on their 7900xtx when framerates are not capped? I have to use AMD Chill and lock the fps to 60fps or else i get a AMD driver timeout at random. Sometimes 5 mins in, sometimes 30mins. Am i the only one?

How can u play without driver timeouts on the 7900xtx. I cant play 10min without a timeout. I tried everything, turning this and that off, but nothing helped

@6:52 - welcome to experience of Fallout 4 NEXT GEN EDITION :D

i cant run this on dx11 it won't event get in to legendary cut scene of democracy always Force me back to windows any solution?

I tried it with my 6800 running at 1440p UW (3440x1440) just running laps around the ship, not in an actual mission yet, and I saw the same thing, big gains in everything except 1% lows. I wonder if the reason Nvidia seems to perform better than AMD in this game comes down to something causing issues with DX12 when running on AMD GPU's....

13900f/4080TUF with 1440p ultra wide, it seems like DX11 is the way to go on my system. Way more stable FPS on DX11 than DX12

i cant even get into a mission without hardcrashing and driver timeouts on dx12 on my 7900xtx 7950x system but dx11 runs super smooth no crashes at all i'm on the latest drivers to guess some configs don't like dx12😅

Looks like CPU utilisation is actually worse in DX12 compare to DX11. Which probably means that the DX12 code path lacks optimisations on the CPU side of things.

Tried this and it would've been amazing if it didn't stutter so much when looking around in dx11

it doesnt work anymore :(

do you think that on a rtx 4080 would be good? cuz, the game runs like ass on my 4080/5800x3d at 3440x1440p

Using a rtx3070, i don't recommend using dx11 on nvidia cards, there is no point. You lose hdr, you dont even get the ootion to adjust ui brightness and the fps is much higher but it feels broken, slow mo thing happens too. Sad, miss dx11 cause this game maxes my r5 3600x and makes it cry.

Excuse me, can you be banned for using the command or not?

Why your game aint crashing in directx12?

okay so at first it did not work but when i changed the d's to big then the game started just so anyone else don't get a black screen !

It's so weird how DX12 has better smooth frametime but lower FPS and DX11 has better FPS but not so smooth frametime

No longer working after last patch :\

Yo you help me with 6600 xt gain a lot of boost fps

is this also relevant for 6000 amd gpus?

Good comparison but it's not only important the ammount of FPS, but also the % from both CPU and GPU and the temps they get, because using different DX causes variations on those 2 values as well. Utopically speaking, the best result is when you get the lowest CPU-% possible, the best GPU-% possible (BEST and not HIGHEST because not every time high GPU % means better), the lowest temps possible on both and the higher FPS possible on heavy load. It doesn't matter much if you get a lot of FPS but the CPU is overloaded or the GPU is not used correctly..

Is there a visual difference?

Need to try this, the game performance is horrendous for me even with a powerhouse of a PC, low settings ultra settings higher or lower resolution its trash when enemies spawns in and bombs are called in

Does it also work with an RTX 3070 or only with AMD?

Not worth u pay over 1k$ for gpu and crashing like every 10-15 min only solution is turn off that option or that option i didnt pay that much money to turn off settings also it doesnt work i also had sapphire nitro and refun it at 3rd day

hope dev fix it. dx11 its realy good for player want high fps

It ain't working anymore. Devs blocked it on last patch.... D:

Intel CPU's performs a lot better on this game they get a lot more fps for the 13th and 14th gen cpus and about every AMD cpu is underperforming alot my same build at 1440p native with intel cpu gets 111 to 120 fps max settings but with a amd cpu it gets 88 to 100 fps I mean this game does not like AMD cpus even ps5 users have reported bad fps problem and they say it gets worst after every update

How do you revert back to DX12?

This literally doesn’t work at all, makes my game get stuck on a black screen upon launch

If you wanted more consistent results to compare FPS difference you should have just rerun the tutorial, the live mission vary greatly between each run

Gtx 1070ti black écran

They have disabled DX11 in last patch

damn, i hoped my life will go nicely if i switch to dx11, but i play on 4k *3072p upscaled to 3800* *skull emote*

Dx11 give mé Like 15 to 20 fps on average while playing 1440p native high settings and i gót around 74 fps sometimes more but cant get more fps and i playing on Rtx 3070 Like bruhhh this game is terrible made optimalization is sooo bad. IF i gót samé settings in dx12 i gót 60 fps in ship when i drop on the planét 55 in battle around 30 fps fuck that, i know game is CPU intensive but in dx12 its dont want to utilizate my gpu at full but CPU is at 30 to 60 percent crazy. I never seen run my Rtx 3070 this nad in online game and also why we need that shitty a ty cheat when this is pve game Like damn nahh. Game really shoukd work better than this. Cant belive how poor is performing on my PC. Fuck even cyberpunk at ultra quality settings 1440p native i playing at 80 85 fps and with full RT i turn on dlss quality or balanced and gót samé fps and cyberpunk is really demanding game but damn this thing this is nôt even good made the friend háve 7800x3d and Rtx 4080 and he playing at 4 and literally háve problems with running game cuz his fps are bad but stability of game is even worse than fps its keep crash Ing a lot, this solution work for him good but game crash Ing still samé with mé the fps gót better but game crash Ing more than before but IF i go back to DX 12 30 fps RIP great optimalized game.

dx11 = no hdr

Am I the only one who thinks DX12 looks better?

Wow dx12 is such a scam!

I know the solution. Buy an Nvidia GPU and have fun. 👍
