I don't play KSP on Linux because of Optimus.... it's ....ty. * If I play KSP with Intel IGP, it has texture flaws and it's slow. * If I play KSP with Nvidia, either the GPU scale to lower frequency and it's slow, either it scales to max and the fan is too loud. So I play on Windows, on my gaming computer. I hope Optimus will have better support and Linux, with proper frequency scaling , so I can play KSP.
