Hi,
I just bought a new monitor (DELL U2312HM) 23 inch which has native resolution of 1920x1080
My previous monitor was small BENQ G610HDAL 15.6 inch which has native resolution of 1366x768
My VGA card is NVIDIA GeForce GTX 460
I use Windows XP Home Edition SP3

When I play newer games (mass effects. borderlands 2, etc) it has no problem at all.
Strange thing is, when I play MDK2 using my new DELL monitor, the performance is ultra slow (even on 640x480). When I switch back using my old BenQ monitor, it works fast and smooth using its highest resolution.


I read some old threads saying we can reinstall MDK2 GoG version using software but I can't find the option in the setup menu. Also, I can only use OpenGL rendering, no D3D
I have turn off T&L, reducing resolution, turn off sound, etc but it's still very slow. Strangely, the framerate on test shows thousands of numbers. Also, loading takes a very long time.

Any solution / help?

Thanks in advance
