S!
I have said many times that IL-2 is the ONLY game I have issues with running an ATI card. Others, like WoP run flawlessly and very well without a glitch. Even Silent Hunter 5 is a smooth ride

ATI has managed to squeeze out good performance without excessive power consumption. If I can run 2 x 5870 with consumption of one Fermi roughly there is a huge difference how much I have to shell out on my system. A really good PSU is NOT cheap and add to that the hefty price tag and you got a lot of invested money for how much perfromance increase? That is to be seen yet.
But as said, ATI works on issue and it will help IL-2 for sure
