Lower fps in fullscreen

SDL Development
1

I’m having some problems with a new project. It’s pretty simple so
far. But I’m getting around 18fps in fullscreen. Windowed, I’m
getting 120fps (well, 60 since that’s the screen refresh, but since
I’m not doing any limiting, SDL_Flip() gets called about 120 times per
second.)

The only difference is the SDL_FULLSCREEN flag. Same resolution
(640x480) and bitdepth (32)… I’ve got hardware surfaces and
doublebuffering enabled.

Dev environment is gcc 3.3.3, through cygwin. And sdl 1.2.8. On windows 2000.

The hardware is a dell latitude d600 with a mobility radeon 9000.

I’ve tried (and failed) to get it to compile with -mno-cygwin, but
that’s for another post.–

Try removing SDL_HWSURFACE from your SDL_SetVideoMode() flags.
