You left out most of the issue template?
I tested GTA IV a few days ago and it worked perfectly fine.
it was v1.10.3 version also my vulkan version is 1.2.170
DXVK requires Vulkan 1.3 and we obviously don't support 3 year old DXVK versions.
If you're stuck with Vulkan 1.2 due to driver/hardware limitations, a safer bet these days would be to try out: https://github.com/pythonlover02/DXVK-Sarek. As K0bin said, we don't provide support for ancient versions of dxvk, it has to be something reasonably recent.
Nothing extracted yet.
The game is unplayable for me it stutters in some places so searched for a solution and i found dxvk so i searched for a specific version for my pc and it was v1.10.3 version also my vulkan version is 1.2.170 so after i installed it i transferred d3d9 x32bit to game folder and i press play on steam and now the game won't starts anymore so what is issue here ?
