I've been playing a lot of PoE lately and the game has run superbly until recently. System; i5 6600 Nvidia 970 16 GB Ram 512 GB SSD I have been running everything on the best graphics level without incident and very smooth game play. After a recent Nvidia driver update, PoE now runs very choppy with stuttering. Nvidia says that it has optimized my game. Do I need to adjust my settings? If so, which ones? What else could be causing the choppiness?
