Hi,
I reported this a while ago, and this still looks not fixed.
When i'm running 1280*1024, my mgag200 memory is filled up with the
backbuffer and depthbuffer leaving 0kb for textures.
Why doesn't the driver use the reserved AGP memory ?
my programs work but textures are *not* loaded, giving a very ugly view.
I know the mga driver could do this in the past (because it worked before)
what's wrong with it ?
Regards,
Peter
