Uh, sorry but SAS4 is the worst optimized game I have ever heard of and no other even compares. It becomes unplayable the longer you play and the higher your level, and most of the time death is due to extreme frame rate lag.
Dude I run the game at 140 - 155 fps and have zero problems with the game other than every now and again while driving the vehicle will run into an invisible texture or something. LITERALLY nothing else wrong with the game that I have experienced in over 220 hours of game play...
no one runs this game at 144 constantly game has serious frame drop in certain areas of the map. Doesn't matter what system u have it drops below 144 on all low settings sometimes lower than 70 in places on a 7700k 1080ti build. People saying otherwise are lying or dont go to the problem areas cause they are to busy camping in a bush.
