all I did was screw with the saturation and brightness to make it look decent, stills runs like poo though.
ah alright, i never really tried to change it since i didn't have much of a problem with it but i'll try that next time i start up the game
also one more thing to add from my post although it's more of a personal pet peeve of mine, but is it me, or do police in GTA V not use a good half of the police vehicles they actually have in the game?
i remember in GTA 4 there was maybe one 'special' prison transport truck for the police that was used in the breakout mission, but for GTA V some of these unused cars you'll never see in the game unless you go to very specific locations at specific times
not to mention the stupid AI that they gave police to become ultra robotic and kill you (if you don't want to be arrested) if you stand by them for too long
im also kind of disappointed they didn't use the police vehicles that were in the trailer, it looked pretty cool to me over the generic 'POLICE'-marked interceptor the cops use exclusively now

but like i said, this is entirely my opinion, and i'm not sure if this is just whining or grasping at the straws or not so i can't speak for everyone or say this is an actual problem in the game
