Modern Warfare 2 Fix Stuttering & Lag - Best MW2 RendererWorkerCount and Nvidia Drivers 

Thank you bro I was having a horrible lag spike every few minutes and was really annoying but this seems to have fixed it

Thank you. this is a huge weight off my shoulders. This was pissing me off so bad. I cant understand how a company like this can neglect something like this. your a god send

Man thanks so much, I have an I7 11th gen and 3080 and couldn’t figure out why it was stuttering so much and had to change the render value to match 8 cores and it’s so smooth now. Absolute legend.

This video was it for me. The game was almost unplayable. Especially when I first launched the game and at the beginning of rounds. My fps was fine but I was lagging so bad. Thank you!

Thanks so much! The lag was so bad I was gonna go back to MW19 for a couple more weeks . Mine was also on 3 and I switched it to 6. Went from 60-90 latency down to 30s.

I have a 12900k as well so I'm very happy to have found this video. I've noticed some stuttering in quite a few of the games I play, and it was always in the back of my head that just maybe the 2 different types of cores in my cpu weren't used properly by games.

Schon gefühlt 20 Videos dazu geschaut und fast verzweifelt mit dem Problem aber dieses Video hat es einfach gelöst, bin soo dankbar!

Very often I find recent tutorials unbearable, but this is straight to the point, informative and really helpful, I was really worried my old PC had started struggling with newer titles, but with this fix its running like a treat. Thank you so much, I owe you one!!

For me the static reflection quality goin from high to normal helped alot with my 1%lows and overall renders in certain areas

Thanks for these fixes. I don't play this game, but my partner was having constant lag, going from 144fps down to 40 and all over the place making the game unplayable on i9 12900k and 3090. Game is now super smooth.

For me the RenderWorkerCount was set to 4. I'm using a Ryzen 5 3600, so i set it to 6 and so far it worked. The stutters are not completely gone but they are not as often as before and overall the Performance improved. Thanks a lot!

Some extra info: The goal is to make the game use only half of your available THREADS. So if your CPU supports hyper-threading, which pretty much every current gen CPU does, simple use the number of available cores (on AMD and up to 11th gen Intel) or performance cores (on 12th and 13th gen Intel). Examples: AMD Ryzen 5 5600X has 6 cores and 12 threads ➜ RendererWorkerCount:0.0 = "6" AMD Ryzen 5 3600 has 6 cores and 12 threads ➜: RendererWorkerCount:0.0 = "6" AMD Ryzen 9 3900X has 12 cores and 24 threads ➜: RendererWorkerCount:0.0 = "12"

Thank you so much, helped a lot of my stuttering issues!

Excellent explanation and tutorial. Very easy to follow

This was the excact solution to my stuttering issue after trying everything else. Thank you for the excellent video and removing the stuttering thorn from my paw.

I can't believe this actually worked out of all the videos I watched. THX SO MUCH!

I’ve still got an i7 7700k. Just want to say that this not only fixed my stuttering, but also gave me a decent boost in fps depending on the map.

For me, the fix was moving it off my HDD to my M.2 SSD. Massive difference! I guess it was just too slow to load whatever on the HDD (7200 RPM speed)

Great video. I've been searching for this setting since the BETA. On the original Warzone and MW it's under Documents, then COD Modern Warfare, Players and finally "adv_options", RenderWorkCount.

Your videos are always so helpful. After I added an in game Nvidia filter. My game started to get some lag spikes. Changes this and now I haven't been seeing them

there was the same problem in cod 2019 with the render worker count and thanks to u i think i fixed my stuttering

Did all of that, tried several drivers, disabled texture streaming, disabled HT and perf cores, changed renderthreadcount, disabled HAGS, the lagspikes are still there… it needs a fix.

very helpful, thanks a lot!

Dude, you are the GOAT! I've literally been trying to solve this for months. Since November! Finally. THE SOLUTION! Thank you!

Hey! So far this has worked for me. I would run the benchmark test and got stutters like every 2 seconds even though the game was saying I had 100fps

For the one brave soul searching for a specific answer, i hope you find this. I had a problem with my new CPU which worked in every other game as intended (+30-40fps because 3 gen’s skipped) but WZ2. I constantly got 5fps in menu + my CPU and GPU usage was basically 0-5%. I thought it was a shader problem, because the intro went smooth but the moment it finished installing the shader or optimizing it, i had freeze frames in menu and game. I preinstalled my bios update before i installed the cpu because it took a while till it arrived and put d.o.c.p. (equivalent to xmp) in BIOS after installing the chip. After i tested every “Fix” on the net, i rolled back my nvidia driver to 522.25 (pretty sure thats not one of the fixes but im not gonna update now that it works) and reinstalled my BIOS update, started without d.o.c.p. and it worked.. went back to d.o.c.p. right after and it still works. BIOS UPDATE after putting the CPU in, just saying.

Appreciate you for doing all of these !

After watching what feels like 30 videos trying to fix this, I found that moving the game from my D drive to my C drive ( HDD to SDD) it fixed all my problems. Hope this helps

We got an answer from nvidia after sending some samples nvidia says the following regarding the stutters: it is not caused by our driver or graphics card. The main game thread is waiting for something wich is not clear in the trace. That waiting is holding up the worker threads and gpu until its completed. So its an issue with the game that infinity has to fix.

i setted RendererWorkerCount to 6 now it works again and got above 100 fps with my ryzen 5 3600 really thanks bro

Hey, I have a big concern I have i9-11900KF Nvidia GeForce 3060 12GB Vram 16GB Ram But always when I load into the map it works for some minutes and then my fps drops out of no where to like 20 and then goes back to 120 and this keeps on going like every 20 seconds any suggestions already reinstalled driver and what not

Will try this tonight, my problem only starts after a few games?? Runs perfectly to begin with then after 3/4 games I start getting lag spikes. Running a 3080 / i7 literally get nearly 200fps on some maps on max settings

Thanks for the tip. It was only using 4 cores of my 6 core 3600X. Still get the occasional frame time spike but overall a smoother experience. It seems like once the match is going for a minute or two the stutters all but stop

ive had a strange issue in the game where it works fine. but i cant use ANY of the supersampling or any of that. Fidelityfx CAS, DLSS, Image Scaling....no matter the method, it causes massive stuttering and dropped frames even to the lowest degree of sharpening strength. i use a Ryzen 7 5800x and Rtx 3070ti.

Omg this actually helped thank you

If I could play the game with your spikes I would be EXTREMELY happy! I am jumping around the map like crazy with 20 Ping and perfect connection

I get massive lag spikes at the start of a match and the menu is clunky,then as I run around the map it improves. I was also having white screen flashes. the latest Nvidia driver was part of the problem, I reinstalled and earlier version. but I am still having stuttering so will try this next, it is strange the the beta worked really smoothly and I was having good fps on moderate settings. The launch version seems to have gone backwards

What if my renderWorkerCount was already set at "renderWorkerCount = 7", but the total cores for my CPU is 8. Is that still ok or do I still need to change it to 8?

Thank you so much , reduced to 8 from 16 and at the moment cod is working with no stuttering , Brilliant

This would normally fix the issue, as i had the same problem on cold war... However, i still get the odd micro stutter... any ideas?

My issue is that the menu is stuttering and kind if laggy i haven’t even tried to get into a match yet. If anyone can help I’d greatly appreciate it.

Bro… it’s worked. Legend ❤️

WORKED, thank you!

Does not matter what I change I cant get rid of the frametime spikes (EDIT: I have a i7-12700k and 3080ti if anyone finds a fix related)

update: I tried to change it from 11 - > to 8 Same thing here too. 1 Micro Stutter lag spike every now and then, with 12700K/RTX3070/32GB DDR4/ Windows 11 21H2 (drivers 522.25). The game was running pretty much good the first - release - date and the beta days. After they release a little update yesterday the stuttering appears.

This pretty much fixed it thank you so much

thanks alot this really helped me.

This sadly does not fix anything for me. I have had the same problem since Mw 2019, now the same with the new MW2. Its unplayable, I cant even move... FPS counter says its 2FPS. My pc is not bad at all, I can play Forza Horizon 5 at 3440x1440 on High settings at 120FPS.

Nothing will fix this junk game until they fix it

I have an RTX 3070 OC edition and a Ryzen 9 5900x, should I set my renderer worker count to 12? I had previous issues with this in mw2019 and couldn’t resolve them, but I had high hopes for this one. Everything worked fine during the beta and ever since the global release of the game I’ve been getting micro second frame drops and I’m on 522.25 nvidia driver.

Thank you bro for this fix, but i was wondering if this fix also goes to BR, because i was lagging at the beginning and for like a minute it fixs. I downgraded the graphic driver to 522.25 version and made the correction when lag occured.. will it work properly if i downgrade a little bit more the version or i need to edit one of the BR file from Call of Duty folder? I just want to run smoothly the game from the beginning, i don’t wanna wait those minutes.

@TechGuides Brilliant video, Fixed my stuttering problem instantly. No need to rollback drivers works amazing now. Subbed, Like, and Video shared with friends. Thank you so much for making this video. 😄😄😄

nope didnt work....rtx 3070 ti on 1440 and it feels like im being dragged to the right all of the time..awful game so far...back in the day id have returned this garbage

When will we get a mw2 fps guide?

Oh mate, my rig is heavily bottle-necked by my CPU (i5 6400 - non K variant), and this definitely fixed stuttering! My gameplay is so incredibly smooth now, THANK YOU!!! Been playing this since pre-launch, and have been gaming with stutter this entire time, however no more! Cheers mate :D

Hi, appreciate you hard work here, especially in your last vid, thank you, was helping me a lot! Could you tell me which count i should you use? I have a i7 9700k with a 2080 Super, the CPU has 8 cores and 8 threads. Should i use now 8, or half of the threads so 4?

I have a question. So, I’m on the latest driver and hadn’t done any changes to the files. The campaign works fine. The maps from the beta work fine, exceptionally I can say. But the new maps lag a lot. It’s at the limit of being unplayable.

EDIT: frametimes smoothed out more, fps are more consistent but im still feeling sluggish and getting stutters every once in a while. About to find out, 2080Ti,, i7-12700K,,32Gigs of RAM,, just DDU’d back to 522.25 and thanks to you finally found this games config files, it used to be more important because i had an i7-9700K up until two weeks ago, the lack of Hyperthreading had me set the count to 4 and i still bottlenecked in multiplayer, was around 60-80% usage. Now im around 15-25% usage and able to use more cores. Can’t wait to upgrade the GPU and PSU next. 3090 is what im aiming for but if the 3080Ti drops a little more im snagging. The 2080Ti will just be a second rig for emergencies or friends or somethin idk.

I have an important question, should I disable SMT via processlasso or just keep hyperthreading on?

If I have 8 cores and set cod to use all 8, will this impact other processes im running like my recording software or discord?

this is happening on my system too, rtx 3080ti / i7-11700k

Please do the optimized settings vid for this game!!!

Thank you!

I noticed that during the benchmark and private matches my gpu usage is always above 90%, but when playing multiplayer it tends to be around 50-60% and sometimes higher. Any idea why?

As a follow up to my last comment and reading some of the replies I fixed my massive lag spikes/stuttering by doing the following : my pc-- intel i7 9700 3.6ghz running overclocked at 4500 hz with rtx3070 rolled back the Nvidia driver to earlier version to stop white screen flicker This is an 8 core cpu so set render worker count to 4 as I had with MW19 reducing the graphics quality and turning off on demand texture streaming helped a little but still very poor at the start of a match Thanks to the comment from viral physics I moved the game from my D drive (normal hard drive) to my C drive (SSD) and success the game now works great and I have been able to turn my graphics quality back up

Is there a Win11/Blizzard alternative to this? I don't have the "players" folder or any "options" files. But I have the EXACT issue you're covering in this video. The game will just stutter and lag, especially during close quarters combat engagements where there's a lot going on.

My god!!! It actually worked. Thank you so much mate

According to Album Performance, render worker count is not about setting how MANY cores you want to engage but how MUCH load all the existing cores are taking. There is a sweet spot for every user. First, set the value to the number of cores your CPU has, then open the task manager while in game, monitor if the cores are hitting 100%, if so, then it's bottlenecking and so you should lower the value by 1 or 2, avoid any cores hitting 100% or you lose performance.

For almost everyone out there your cpu core count should be detected automatically. If you aren't sure don't change it. The primary issue with stuttering right now is drivers and GPU utilization errors caused by constantly having your GPU at 85% or more usage. It is fine to spike there a lot, but not to constantly have that as you see in the video even if it is a liquid cooled card. It can damage the hardware and cause issues in game as well. The issues won't be as severe at first as 100% CPU utilization, but they are there... believe me.

The same thing on the 5800x3D + 3070ti, before the first days of the game were lower fps, but stuttering was not, but now it's a crack, every few seconds lag, a change of rendering 7-8 does not help.

THANK YOU SO MUCH!

i uninstalled the game

Thanks for your help. Subscribed. Liked.

Hi men, i have the issue that when i enter a match, the game just freezes in the loading screen (where you can see the map), do you have any solutions to this?

Hey, so I have been having this issue since it came out and it was so bad that it was unplayable even tho I have a I7 32gb RAM, 3070 NVIDIA card. I tried this and it seems to still be having issues. Suggestions?

what to do when i dont have the call of duty folder in documents ? with every gamestart i have to run through the setup

I have a i7-12700kf with a 3080Ti and unfortunately this didn't work for me. I average 190-200fps but every 2-3mins I get these spikes like you do in the video. Any other possible solution you can think of?

my game was almost unplayable because of stuttering and after this is smooth as possible, thank you very much

my i9 9900k have 8 cores, but out of the 8 i dunno how much is performance cores. issit the same?

Thanks, worked for me.

I got an i9 11900k. I have 8 cores. In the 11e gen there is no performance cores value. When I put on 8 I use all my cores that's not a problem?

Thankyouuu, this video helped a lot

I heva a ryzen 7950x so 16 cores, 32 threats. What number should i set it to. Default is 16

hello, i have i9 9900k and rx6900xt, i did as you said but i still have a big loss of fps, especially when i meet someone in the map. Help.

My old ass i7 2600k was dipping in to the 50s in Ground war. Changed RendererWorkerCount from default "2" to "4" and gained a huge max and min fps boost. So this does work!

BRO YOU SAVE me thank you a lot now I have 70 fps and more stable not 40-and drop fps You trick work 100%

So for a i5-11600 which has 6 cores, do you put 6 or 3 ? Putting 6 didnt helped reduce the lag spikes :( ...

What aboout a 12700kf ? Has 12 total cores (8 Performance, 4 Efficient) but has 20 threads ? Should I set for 8 or 10 ? Thanks in advance !

I have a 5600x and rx6600 I very new on pc so what's the best to set?

i dont get it i typed in my cpu type and it didnt show the number of render things it only had cores and threads what do i use

Weird question. I went to the documents tab and there was no call of duty file. Any certain reason that would be?

Thank you!! The worker setting fixed for me low fps (+20) and stuttering.. now i can play!! Thank you. I have a 5600x and 3070

Any idea why I can’t see my configuration files I click on players and there’s only those top 3 options?

I have 1x16gb of ram in my pc, it's not a pre-built, but I didn't build it, I went to pc specialist and didn't know anything about single channel and dual channel, could this be where I went wrong? I can achieve 100+fps which I'm more than happy with, but get hitching during game play and prelobby, just wondering is this the problem? I have i7-10700KF paired with a 3080 12gb.

hey man,am having an issue that my cpu usage is higher than my gpu usage when i play MW2(2022),even though when i play warzone everything is good and smooth,i have RTX 2070 SUPER WITH I7-9700KF,any advice?,thank you.

I have an 11th gen i7-11800H for a laptop msige76. the render count is set to 7 but i have 8 cores and 16 logical processors. Do i set the new ender count to 8 or half it to 4?

Can someone please help me I have the I7-8700k and it saids i have 6 cores with 12 threads. it was on 4 i tried 3 and 6 and neither of it make it better for me. Cpu bottlenecked at 80-90% but with Vsync on it goes dow nto 37% and the rest to the GPU

Damn default render core were set to 7 instead of 8. The difference in the game between those two settings was IMMENSE! So glad to finally have solved this issue.

thanks, now my game looks better. setting to 6 with my ryzen 3600 was a good idea.

thanks man you saved me you got new subscriber!
