I'm with X-Plane 10.42 64-bit bought via Steam, and my performance is terrible. Even with the lowest preset, I can't get more than 40 FPS, whereas I can play GTA V and Crysis 3 (and a lot of other games and 3D engineering applications) with 60 FPS or more in the medium/high settings. With the medium preset, performance drops sharply to just 23 FPS or lower, depending on the scenery.Also interesting, the anti-aliasing processing seems not to be occurring, regardless of which level is set on the Rendering Options of the simulator.This testing is being done with the Cessna 172, and the default airport on a clear weather setting. The resolution is 1920x1080x32-bit fullscreen. I´m on Windows 10, with a GTX 570 GPU (which has 1280MB of VRAM) on a 16x PCI-e bus (effective, not degraded to 8x), running the latest NVidia drivers (361.43). The system has 8GB of DDR3 RAM running at 1333MHz on two channels, however X-Plane hardly uses more than 3GB - paging is definitely not occurring. The CPU (which is an AMD Phenom II x4 965) load is evenly spread between the four cores, but they spent most of the time idling (CPU usage doesn't reach 50% while in the simulation). The testing was also obviously done without other applications running. No mods, add-in aircraft or scenery are installed.
Here's the Log.txt file:
From the in-game counter, I get just 0.044 of CPU time usage, and 0.037 of GPU time usage.
Is there something wrong, or this kind of low performance is expected? What should I try?
