Hello all!
I'm running a clean install of KSP 1.1.3 on Ubuntu 16.04, kernel version 4.4.0. I've got dual Xeon E5-2670s, a GTX 1060 6gb and 64gb of ram, so I don't think my problem is a hardware limitation. Any scene with any 3D rendering, regardless of graphics settings, (including the kerbals floating in space on the main menu) uses 100% CPU (100% of all 32 cores!) and I'm getting terrible frame rates. I'm getting 10-40fps on different scenes, with terrible stuttering.
Is there a fix for this unreasonable cpu usage?
