Hi, I'm having huge perfomance problems when testing my game Slingshot in fullscreen mode. There are no perfomance problems what so ever when playing in windows mode.
I've tried both with and without hardware surface display. When trying to convert the images there are a huge perfomance boost but then I loose the alpha values. I've also tried to use convert_alpha but without improvement. The original images are PNG with alpha-channel. Is there anything I can do or is it impossible to get alpha-blitting perfomance in fullscreen mode. Oh, yeah...I only have this problems on Windows XP. There are no problems on Linux. All ideas are welcome! Best Regards /John Eriksson
