GTAIV.EFLC.FusionFix VS GTAIV.EFLC.FusionShaders

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

Alternatively, downgrade to 1.0.8.0 and update common/shaders with this: https://github.com/Parallellines0451/GTAIV.ShaderFixesCollection

Also install these fixed shaders so the graphics don't pop in as much: https://github.com/Parallellines0451/GTAIV.ShaderFixesCollection/releases

Okay but if you at least replace GTAIV/common/shaders/ with this you will not regret it. Many shader errors fixed to restore console graphics effects that Rockstar left out for bad porting or 2008 PC performance reasons. https://github.com/Parallellines0451/GTAIV.ShaderFixesCollection

ShaderFixesCollection: This restores the gamma from the console release as well as other various fixes to enhance the look and atmosphere of the game.
