I downloaded the Orbiter spaceflight simulator (build 100830) from the official website. When running Orbiter, I get ~1 FPS, and it maxes out one of my CPU's cores (I have an i5). I run Orbiter by "wine orbiter.exe". All dependencies are satisfied. Wine is V1.6.2. It was working fine on Arch Linux, but I upgraded to Kubuntu 14.04 LTS, and had to reinstall my programs. The video settings which previously yielded an acceptable framerate (~20-30, depending on scenery) now have me at around 1 FPS. Any ideas?
