I meant that KSP runs with optirun/primusrun exactly the same as it would without those (which would start it on Intel GPU, which is slow and has no anti-aliasing support)If i go to settings and change render detail slider (and then change it back), it runs fast and with anti-aliasing, just like it should. KSP worked fine in 0.21 and earlier, which makes me think something in 0.22 caused it to broke (it might be Unity3D update, or the appearance of the launcher)

This is really weird. When i run KSP from Steam using primusrun (or optirun), it runs with low fps, no anti-aliasing, and stuff like that, so i assume in runs on Intel graphics card (but ksp.log says otherwise). But, if change the in-game render quality slider from medium to low, hit accept, and then change it back, i get high fps, anti-aliasing, and some stuff that happens only when using primusrun (tearing in one specific spot (happens in every game) and UI flickering when looking at water).
