GTAIV.EFLC.FusionFix VS dxvk-async

I highly recommend using the newest version of ThirteenAG‘s Fusion Fix. It offers options to completely disable the green/orange tint, enables console gamma (less washed out colors), and also gives you the option to enable FXAA. Everything is neatly incorporated into the game‘s menus and works flawlessly with the latest version of GTA IV, no downgrade required.

for the best gta 4 experience, make sure to install fusion fix and the visual mod that restores the console look (including the correct gamma setting)

Highly recommend this for more fixes and a modloader https://github.com/ThirteenAG/GTAIV.EFLC.FusionFix

I use Rivatuner statistics server. It's an app that can limit FPS and has an overlay for games where it shows FPS in corner. It can limit FPS to 1 if you want to. I'd recommend you to install FusionFix since it fixes a lot of issues related to FPS as well as some cutscene tweaks which might fix your issue. https://github.com/ThirteenAG/GTAIV.EFLC.FusionFix

Right now im using this https://github.com/Sporif/dxvk-async with dxvk.enableAsync=true, it works but i got transparent assets 1-2s before it load completely, is that normal?

You can also manually install it yourself, check the DXVK_ASYNC Github page for the instructions. Maybe try to use an older version of Proton GE if you're unsure.

I also tested out Unity on my system and got the same results as you to which DXVK gplasync or the older DXVK-Async "band-aid" fixed it. Really, that's the only thing that does address issues with DX11

DXVK Async: This is a file that converts the game from DirectX9 to Vulkan, this helps alleviate issues with stuttering and massive frame drops. This version has async which renders shaders faster so it has less stuttering than regular DXVK.

Try downloading this - https://github.com/Sporif/dxvk-async

Download dxvk async 2.0 here : https://github.com/Sporif/dxvk-async/releases/tag/2.0. then open it and go inside the x32 folder and copy d3d9.dll and dxgi.dll then paste inside C:\Steam\steamapps\common\Mafia II\pc.

Jedi Fallen Order (Epic setting) was a little quirky with stuttering, but was rectified when I used DXVK_ASYNC and entered DXVK_ASYNC =1 in Settings > About > Advanced System Settings > Advanced Tab > Environment Variables > System Variables > New > Variable Name = DXVK_ASYNC, Variable Value = 1, and that reduces the issues quite a bit. Vanilla DXVK 2.1 didn't work out as well for me, but I might try it again as 2.2 came out recently
