Game performance is also highly affected, I get constant 20fps when not using vulkan

Software information

System information

• GPU: Intel CometLake-U GT2 [UHD Graphics]
• Wine version: 9.0
• DXVK version: 2.4

You also didn't provide logs so I can't check whether or not your Vulkan driver exposed VK_EXT_feedback_loop_layout which normally fixes this issue. You also didn't mention your driver version in the bug report either. ANV should have the required extension as of Mesa 24.1.

[TRSC25]

Could you please guide me on how to do that? I'm playing the game via Lutris Flatpak, so... not sure how to get the logs.

Sorry for late reply btw, I had other stuff so I forgot to check GitHub

[K0bin]

Change the Steam launch options for GTA IV to PROTON_LOG=1 %command%. Then it will create a log file called steam-GTASTEAMID in your home directory.

I don't know how it works with Lutris. IIRC Lutris has a function to get stdout of the game you were just running or something like that.

Can you also run the flatpak list --runtime command (so I can see if you have an up-to-date runtime)?

[Sid127]

You can get logs by clicking one of the dropdowns next to the PLAY button in Lutris for the game, and then clicking Show Logs.

Could either copy and paste them into a pastebin service, or save them into a file from there

flatpak list --runtime

This is the log after I loaded into the game and drove around for a bit and quit the game

That's unfortunately missing the DXVK logs I was looking for.

[TRSC25]

So... how do I get that?

[Blisto91]

Try to right click the game in Lutris -> Configure -> Runner Options tab -> scroll to the bottom -> make sure Output debugging info is set to Enabled.

[TRSC25]

That was it. I got a log which... looks like a log. log.log

[TRSC25]

Hi, any updates?

Your driver supports VK_EXT_feedback_loop_layout, but there is probably another driver bug that's causing this. Try INTEL_DEBUG=noccs as environment variable, maybe.

[Blisto91]

We have been unable to reproduce on Nvidia or any of the 3 amd drivers so we assume it is a likely driver bug yes. Unfortunately none of the devs have Intel to test with.

That helped in removing the flickering dots, however there is still the slight frame drops which isn't there when not using dxvk.

[TRSC25]

I tried recording it but it looks much worse but according to my eyes it's roughly showing half the frames it did when not using dxvk, and its not everywhere, for example the apartment is really laggy but some roads arent.

INTEL_DEBUG=noccs can reduce performance by disabling compression and overall it's not unheard of that vulkan doesn't perform particularly well on old Intel GPUs. There is most likely nothing that DXVK can do about it, especially considering that this must be the millionth bug report about GTA IV and it performs just fine on other drivers and GPUs.

You can report the flickering dots that happen without INTEL_DEBUG=noccs on the Mesa gitlab as a driver bug.

[K0bin]

It's most likely a driver bug but none of us have Intel hardware to try and reproduce the issue. Because of that none of us felt comfortable opening a Mesa issue.

This also used to happen on turnip, but seems it got fixed at some point
