Greetings fellow Kerbonauts I have noticed that KSP performance under Linux is somehow lower than under Windows (Win7). Obviously, the primal suspect is graphic card drivers (I have nVidia), but before I jump to conclusions, I'd like to see some numbers in form of FPS to support this claim. It is easy to use applications like Fraps under Windows, but I haven't found any way to show FPS under Linux, should that be using debug menu (I'm pretty sure that is not possible), using 3rd party tool or even making Unity to show FPS somehow. Does anybody know how to show FPS in Linux? Also, I have mentioned drivers. I'm currently using version 304.88 from March 2013, I know there is a newer version made by nVidia, but not sure if it's worth it.I have some bad memories regarding updating drivers. Does anyone have experience with KSP in Linux and if updating drivers have any impact on performance?
