Extremely odd behavior with IL2 yielding very poor performance

S~! Henrique

Your not alone mate. I have the same issues with lots of objects or cities. I can play CoD4 at over 250 fps with full action.
The engine is pretty much done as far as newer hardware and especially drivers are concerned. Its 10+ years old so its prehistoric in software terms. Also nvidia will give you better fps over an ati card. I own ati but thats just the truth at this point.

The major fps killers are water, effects and land geometry.

Water=0
Effects=0
Land Geometry=2

** Also check the way your mirrors are set. Even on planes with no mirrors - this setting can affect you if you have them set to high for any planes you may fly with them on.

*** TURN OFF Vsync
