Could you give us more details on your system? I have serious issues at full res textures (game crash in 3~4 scene changes) In case anyone is interested mine is: MacBook Pro (Retina, 15-inch, Early 2013) [MacBookPro10,1] OS: Yosemite 10.10.2 Intel Core i7 2,4 GHz RAM 8 GB - - - Updated - - - Maybe I was not clear, but I was listing KSP versions, not the OS itself thanks for the notes on OpenGl. I already knew Active Texture Manager As for DDSLoader, my though that ATM already does the same process (PNG-> DDS) making DDS depreceated. But thanks to you, I looked again and the info i found in reddit leads me to thing they will work even better together
