Hi guys, sorry to bother all of you again, but i''ve got some video-related problems this time... The question is simple: Is there any way to force video sync in double buffered, hw accelerated full screen mode? I''m using SDL 1.2.5.0, but i found the same problem with earlier versions. I''m using this line to set video mode: output = SDL_SetVideoMode (640, 480, 16, SDL_ANYFORMAT | SDL_HWSURFACE | SDL_HWACCEL | SDL_DOUBLEBUF | SDL_HWPALETTE | SDL_FULLSCREEN); My system specs are: CPU: Duron 1Ghz RAM: 384 MB VIDEO: TNT2 M64 m/32MB OS: WinXP (build 2600) Compiler: MSVC++ 6.0 Enterprise Thanks
