You havent got poweful grafic card I have too nvidia NVS 3100M and it is lagging
If I change the graphics settings at the game to low???
GTA comes with a nice feature showingbthe recommended minimum VRAM requirements. On the loewest it is below 500mb and it maxes out at around 1.5GB. Tuen it down all the way and you should run above 30fps. Same goes fo NBA.
