What is your CPU, GPU, kernel and GPU driver ? What version of Wine are you using ? Have you enabled DXVK or VKD3D yet ? You say you're using the non Steam version, what does that mean ? Epic Store or something ? What frame rate were you getting on Windows and what are you getting on Linux ?

One thing I will mention from my experience is that Lutris sometimes has issues with using Esync and Fsync which are features that can improve framerate depending on the game. I would recommend trying Heroic Games Launcher as they have never given me trouble using those features.

Hello, thank you for your answer.
Here is my system information:
CPU: i3 2100
GPU & driver: Nvidia GT 430, 390.157 (proprietary)
Ubuntu version: 20.04.6
Kernel version: 5.15.0-101-generic
Wine: wine-9.0 is installed on my pc, also tried lutris-fshack-6.21-6 (found this one works the best) and tried a couple of older wine versions provided by lutris.
I did not enable DXVK or VKD3D because my drivers are not supported and i can't use those features.
By non-steam i meant downloaded the patched game from the internet.
With this hardware i was getting minimum 100 fps on windows and max over 150, on linux i get minimum around 40, max around 100 (and that is when i turn my head by the wall and not doing anything).
I will try Heroic Games Launcher and post the results when i do that. Thanks again for helping.

Wasn't CoD4 OpenGL? If so, DXVK wouldn't make a difference anyway.

Thanks for the info. I was worried you might be using out of date stuff such as a really old version of Wine or something but everything seems fine. I Might be able to test the Steam version in the next few days. If so I will try it on both my onboard Intel GPU as well as my RX 590 and see what kind of performance I get as a comparison.

Been many years since I played a MW game so I wasn't sure.

That would be great, whenever you have time do that test and post the results here.
Thank you very much!

According to PCGamingWiki it uses DirectX 9.0c on Windows and OpenGL on MacOS. Unless I looked up the wrong game I get confused at COD titles as they sometimes repeat.

Absolutely correct. Also on early nVidia GPUs (I myself have a GT 730M in one of my still active systems) Vulkan performance was not that good anyway.

However the downside of this is you have to use WineD3D which is known for having some noticeable performance regression even on older games.

For example: https://youtu.be/_uZD5yBwMzk?feature=shared&t=153

Unfortunately I do not own CoD4 any more to counter test this on my Laptop which is only one Intel CPU generation more recent than your hardare (i5-3230M + GT 730M). I once had a "backup copy" from a friend but that one got lost.
