If you are in pause with CLOD...
Is not a WWII Sim but a WWI Sim I recomended: Rise of Flight.
I have discovered this one two weeks ago, first with the free demo and now in full. Excelent atmosphere and interface, friendly forum with a lot of information, service, shop; at the sim not CTD, FPS friendly and stable(You dont need a top of line PC), excelent aircraft models, FM, damaged models, superb sounds, weather effects, good scenery and airfields, you have quick mission, single mission, career, campaign, very good multiplayer, system of points(score)in line, skins, maps, addons, etc.
Really a very good sim.
