Cannot set 30 fps lock in GTA IV (Rockstar Games Launcher)

[shvch]

Hi everyone,

I've been trying to set framelock to 30 frames in GTA IV for stable performance (I own the game through Rockstar Games Launcher). Commandline.txt and in-launcher Launch Arguments don't work. Only thing that worked is FusionFix, but it makes my game glitch a bit. DXVK works on my system quite unstable, so I want to lock the framerate without mods. I would be grateful for advice.

 

My specs:

Windows 11 Pro

Intel Core i5-1135g7 with Iris Xe graphics

8+16 GB of RAM

Use MSI Afterburner + RivaTuner because the game's -frameLimit command does a completely different thing than what it's supposed (if it even works at all?).

 

Commandline args should still work inside the launcher settings, just not via commandline.txt, since they somehow broke the functionality in some launcher update.
