Hi there!
I fly and love both birds! My old system is struggling to keep these beauties flying, but most of the time, I get 25-30fps out of the A300, even with xEnviro running, and around busy airfields, and overall the sim is pretty smooth. In the A310 though, fps go down to 18-20 (f-sim stuck at 19fps, problematic while flying online) and the whole sim becomes pretty stuttery. Is that a normal behaviour?
Thx a lot in advance for your input!
