When I run naiture in WINE (it is a Windows based program that I am trying to move to Linux/OpenSource) it says the FPS is like 500+ with just a block in the center. Yet the actual visual framerate is quite choppy: [Image: http://www.naiture.net/snap/wine1.png ] Here it is running in full, the reported FPS is more realistic: [Image: http://www.naiture.net/snap/wine2.png ] Why would the internal framerate of the program be so high, yet look so low?
