That's all good if you are fine with using openGL on Windows. But it might be an easy fix, it sounds like the same issue this guy had: http://forum.kerbalspaceprogram.com/threads/104965-%28Ubuntu-14-04%29-Dissapearing-Kerbin-at-the-Space-Center-Lag-Bluescreen-VAB Also don't forget that if you want anti-aliasing on Linux, and you probably will, you can't just turn it on in the KSP settings, you have to force it on in your graphic card driver. Atleast it was that way for me. Sorry for off topic and all. Slightly more on topic, if you ask me it's totally worth it, the high res EVE and textures are great. Can't wait for RVE to be updated!
