running on intel i7-3770 cpu @3.40GHz 24 Gig memory, with a AMD Radeon R9 200 series (3 Gig memory). Using CH Virtual Pilot w/pedals. Benchmark is at 47-49 fps using Heaven Benchmark 4.0 X-plane tells me my frame rate is too low (shows at about 12 +/- 2); however, no screen tearing, no stopping or jerking, sim runs smoothly on 3 screens all hooked to the AMD graphics card. The settings for X-plane are mid level settings. I tried low settings across the board and had no change in performance, no significant change in reported frame rate, but a change in scenery of course. So far I just leave the settings at median levels and fly, but the error message telling me I am in failure and an idiot (implied) is mildly annoying. Also I fear at some point the sim will have degraded performance when the equipment should readily handle the sim.
