I am using the latest CVS versions of SDL and the
SDL helper libs. I compiled SDL with CYGWIN ( MinGW Mode )
and DirectX. For fun started testsprite on Windows
and noticed that it is pretty slow compared when using
it under Linux. On both systems i just start it with ./testsprite
Screen is at 32 bits per pixel
Screen is in system memory
Sprite is in system memory
Sprite blit uses RLE acceleration
49.36 frames per second
make sure you have the latest video drivers installed for your video card.
on windows xp, it ships with slow version of GL drivers (so directx apears
faster than OpenGL most likely) and I’m not sure if the same happens on
other versions of windows.
try updating and if that doesn’t help let us know> ----- Original Message -----

I am using the latest NVIDIA Det. drivers, both under
Windows and Linux. The refresh rate of my Windows Desktop
is 100 Hz. When using ./testsprite with -fast it uses
HW Pageflipping with VSYNC and syncs to the standard 85 Hz.
I also checked that SDL uses DirectX.
Is there anything that changed in the Detonator
drivers or in SDL the last time ?
In my opinion using Software Surfaces in
Windowed Mode should give more FPS. What have FPS
do other people have using Windows and what computer ?
