You'll probably also want to know, although that's less good, that 2D
performances decreased quite a lot.  I can only get < 10FPS in 2D
games now (used to be > 60FPS).

This following simple SDL app runs at 17FPS while, from memory, it ran
at least at 100FPS previously.

Shall I open another bug?


#include <stdio.h>
#include "SDL.h"

int main(void)
{
  SDL_Init(SDL_INIT_EVERYTHING);
  SDL_Surface* screen = SDL_SetVideoMode(640,480, 0, SDL_DOUBLEBUF);

  Uint32 start = SDL_GetTicks();
  int nb_frames = 200;
  int i = 0;
  for (; i < nb_frames; i++)
    {
      SDL_Rect r = {10,10,40,60};
      SDL_FillRect(screen, &r, SDL_MapRGB(screen->format, 0,0,255));
      SDL_Flip(screen);
    }
  printf("%g\n", 1000.0 * nb_frames / (SDL_GetTicks() - start));
  SDL_Quit();
}
