Two things to keep in mind though, I’m on Iris Xe graphics which has poor DX9 performance (it’s done entirely in software idk how) and GTA IV is just a really horrible port on PC. It’s cpu rendered shadows and just general jank. Early parts of the map run much worse.
Performance increases were mild but noticable. On both my old computer (i7 8550U and a Radeon 530 2 GB DDR3 gpu) and new computer (i5-1135G7 and Iris XE graphics), I got better frametime consistency and a noticable improvement in fps
It’s also been a while since I’ve played GTA IV. I was running older drivers then and there have been major improvements since.
Edit: vulkan performance has been somewhat consistent on Arc but I was using 2017 drivers due to stability issues. I’d probably see a marginal increase running modern drivers using dxvk.
Vulkan runs the game better than DirectX 9, I will say that much. Had no issues on Arch with Nvidia
I used dxvk on windows and it was a definite improvement for GTA iv.
Quite the difference, isn’t it. DirectX was often really wonky back then
