At the moment I don't have any FTX products loaded in P3D2.5 as we wait for the fix.. I have textures at 4096 and all sliders to the right and | don't have any OOMS in England. Granted, I'm flying the Iris Battlefield Airlifter which, whilst not overly complex, is a lot of fun. I don't have any stutters and am enjoying flying for the first time in a long time.
