April 5, 201313 yr GTA IV just keeps crashing on me, after about 20mins the buildings start to lag behind and stuff disappears, then it crashes and says GTA IV is not working. Specs: Intel i7 Quad Core @3.5Ghz 16GB Ram GTX580 (x2 sli) I saw somewhere if i went into the ELS settings and changed Ai_ELS_SP = 1 to 0 it would fix it, it didnt. Not sure what else to do.
