Well, seeing this description, I could say only one thing : DRIVER PROBLEM

You description seems to imply that the glReadPixels call returns a
completely black frame buffer (whereas the drawing seems to work well as
shown when you remove the surface locking stuf). To be 100 % sure, you could
enable the debug code in the Lock / Unlock case to have nice screenshots (if
they are all black, that would show that :-) ).

Maybe it could be fixed by my attempts to use the texture engine instead of
glReadPixels (to be submitted only after profiling)...

Did you try changing the resolution manually using Ctrl +/- ? Does it work
like that ?

As for System Shock 2, I have the full game, so no need to show me the demo.


PS: do not count on me to debug this, I hate XVidMode :-)
