I've had some problems with my Flight Simulator ( can't use window mode ) , so I tried a system restore using two different restore points.Both failed. I had my firewall and virus protection off. How can I get around that?
What GPU are you using?
What exact problem are you facing?
Are we talking about FSX?
Do you have the latest GPU drivers?
Latest direct X?
Patched game?
Tried a resintall of said game?
