I'd Just Like to add and let everyone know that Kerbal Space Program does not currently utilise GPU's at all, unless that has changed in .22, Also the current unity version it's running on does not support multi-threading of cores so 1 core will say be looking after the physics and then another textures and so on... I learnt this from other threads similar to this one so it may not wholly be right Shift+R improves the quality of this image. Shift+A improves the quality of all images on this page.
