I've not played a lot with the past Patches, most only training missions with the Ka50, and my rig it's not high end.
But nowadays I've had FPS drops when looking at a certain direction, probably where there are a lot of entities, even if planes or tanks are very far away and out of sight. If I look down or sideway the FPS rise to normal.
The problem found playing SP Fast Missions with Ka50 and P51.
All settings low apart from texture witch is high. Vsync on. res 1280*1024.
The game is unplayable for me atm. A pity because I was starting to grow interest in DCS. :cry:
