Well there is d9vk and dxvk which translates directX 9, 10 and 11 to Vulkan and vkd3d which translates direct3D (directX 12) to Vulkan. So it’s all Vulkan on the Linux side, Proton ‘just’ uses one of these to translate the game into Vulkan or passes it through if the game is already Vulkan.
I don’t think there is a native (to GTA IV) Vulkan renderer in game though and therefore there isn’t anything more you can or have to do on Linux.
On Windows, some older games actually get performance improvements from the translation to Vulkan.
Been playing it on PC. Performs better at 1440p that 1080p for reasons I don’t understand
It’s probably because things get janky on high FPS. I wasn’t able to complete the game until I capped the FPS in the final mission (helicopter scene).
Hope you’re running on Vulkan, for me it went from 30ish fps to an illegally high number for some ungodly reason.
I’ll have to check. I’m running it on Linux via proton, so it might get complicated
Ah yeah then that’s Vulkan
Then surely it’s via Vulkan? Is Proton able to use anything else under the hood?

Can you use Proton on Windows too? Cool if so.
No, not Proton, but the dxvk stuff works on Windows too. You just need to replace some .dll files
Ah neat. Thanks for explaining!
Honestly I don’t know lol
