With both set to 1, my max FPS went from 55 to 140, although the average FPS only increased from 52 to 55. The only settings that seem to yield any significant increase in FPS is View Distance and Detail Distance, which should be lowered together. Interestingly, GTA doesn't seem to care about GPU so much, as there is almost no difference between playing with a 1920x1080 or 800圆00 resolution. With these arguments, it runs between 50 and 55 FPS and averages at ~52 FPS. GTA used to run on max settings at around 20-35 FPS. In that TextBox, paste these arguments: -nomemrestrict -norestrictionsĪnd GTA 4 should run with a huge speedup. Right-click on GTA 4 in Steam, and click on Properties.Ĭlick on Set Launch Options.
