My optimized launch params for low, high spec PC's GTA 4 2020
By Elvyee
Open your Steam library, right click on GTA IV and open the properties.
On the General tab you'll find Launch Options section.
Enter the launch options you wish to apply (be sure to separate each code with a space).
Close the game's Properties window and launch the game.

-novblank -norestrictions -percentvidmem 100 -novsync -frameLimit 0 -nomemrestrict

And now save the file and launch the game!
;) The launch params helped me to improve my FPS in game!

The original post setting worked for me instantly. A minor stutter here and there but the frames seem about 60fps and consistent.

@Elyee Got it now, was trying to find it through the game's folder at first. Thanks for the help!

You haven't posted the description of the following commands: "noswapdelay" and "reservedApp"

@Spud Muffin Open your Steam Library.
From a game's library page, select Manage > Properties.
On the General tab you'll find Launch Options section.
Enter the launch options you wish to apply (be sure to separate each code with a space).
Close the game's Properties window and launch the game.

@Viewbob it just makes the game force itself to not run shitty

@Punished Wolf Why use this if it was running smooth lol

Thanks man, this helped a lot. I bought the game 4 or 5 days ago and hadn't been able to even partially launch the game until I applied these commands.

what does this do? just improve performance or make graphics worse or something?
