No, this is definitely a very non-specific bug, because for me it happens on
each and every DirectDraw game I have. If you have a free directdraw
application you can suggest, I will gladly test it, since nothing comes to mind
right now.

As for that other test, I can reproduce it, but I can reproduce it on both GDI
and OpenGL without difference, and only if I press multiple buttons at the same
time, and moving the mouse does not cause any latency whatsoever. So it seems
to not be related to this issue, since for this issue I get a very low
framerate only by moving the mouse, and it works instantly, plus the framerate
goes right back to normal after I stop moving it.

I also tested a few different modes of Heroes3HD, where they have several
renderers to offer. If I choose the MMX renderer, I get a lower framerate than
with forced GDI, and no graphical glitches. With the GDI renderer, of course,
the performance is as it should be. With the auto and default renderers, I get
graphical glitches and the lowest performance.
