luangm Posted January 17, 2004 Posted January 17, 2004 Hi, I'm just trying to test the capability of windowed and fullscreened apps, I heared that a back buffered Flip mechanism can really speed up the thing(flip is faster than blit???) but in the test program I'm only getting about 60fps, where if I use windowed, I got 250fps. Any explainations? Thanks! Quote
wyrd Posted January 18, 2004 Posted January 18, 2004 Sounds like it's a clipping issue. Make sure only the primary surface has a clipper, not both the primary and secondary. Also check your code between the two and see if you accidently added something extra to the fullscreen version. Quote Gamer extraordinaire. Programmer wannabe.
halobear333 Posted January 18, 2004 Posted January 18, 2004 Your full screen app is set to vsync, while your windowed app is not. The 60 fps is determined by your monitor's refresh rate, presumably 60 hz. Make sure the PresentParameters.PresentationInterval is the same for both progs. Quote
