See my other comment. I’m not at my PC at the moment and don’t remember the launcher I’m using but some of the options are cheat modes and level skips. You could beat the game in 4k if you like.

I played this again earlier this year. There are some amazing mods/launchers out there. Resolution and texture upgrades, cheat options, more. It’s still super playable today. It’s like the grandaddy of GTA.
