MUST READ!!!

DXVK recently got updated to version 2. 4, which includes some small improvements as well, thus, upgrading to it might be preferred.

1. Once inside the archive, head into the  folder, select all the files and extract it to the main directory of GTAIV, next to GTAIV.exe;

2. We're done here.

!! Important !!

You'll have to make sure that your GPU supports the Vulkan API first and if it supports Vulkan 1. 3 ! (Check)

If it supports an earlier version such as 1. 2 or lower, use DXVK 1. 10. 3: Release: GTA4 DXVK 1. 10. 3 Legacy 

For AMD users:

Go into AMD Adrenalin --> Settings --> System --> Hardware & Drivers Panels --> Expand Software & Driver Details and there it will show you "Vulkan API Version". If it starts with 1. 3 then follow the guide as is, if it's something lower, just download the 1. 10. 3 release and follow the same steps.

For Nvidia users it's probably something similar, look through their drivers.

Next up, the configuration files:

Head into the main directory of the game, next to the .exe, and create a file named commandline.txt. Open it and put the following commands in it:

-availablevidmem xxxx

-nomemrestrict

For -availablevidmem, you have to specify the amount of VRAM that your GPU has in place of those x's I've put next to it. Some examples below:

10gb - 10240

Some additional notes about it:

1. On patches lower than 1. 0. 8. 0, it is recommended to put a . 0 at the end of the value, if it shows 2047 mb in-game, then it's correct;

2. The game won't actually be able to utilize anything more than 2gb for what it's worth, so any value higher than 2048 would only be so the amount actually displays properly in the menus on patches 1. 0. 8. 0 or later - that does not mean the game would ever use 4gb for example, even on the highest settings, it's just aesthetic
