With Ultimate Traffic 100%, all settings maxed out completely and fully 3D clouds, and at SimFlyers Los Angeles v2 along with MegaScenery, I can get around 90-95 fps. I don't lock my framerates because I want the best possible performance - hey, I didn't splash out all that money on a piece of tat, you know!

Cheers,
Rob
