In alot of cases its due to DRM in those cases all you need do officially is download the updated version of the DRM off its website... most people go the unofficial route suprisingly ;)

I actually have an NVidia card. GTX295 to be precise. And I remember running Messiah a few months ago to show it to a friend of mine.

I've heard many people had problems with Messiah, I had some with my current computer, mostly graphical with a Nvida Geforce 8800gt but managed to finish it. In any case I'll step forward to seven... DRMs are not much present on my computer anyway.

Well it's probably not that then. But it has major graphical problems that just completely kill the whole game for me. It starts off fine for a couple of seconds then it slows to a crawl and 90% of it disappears entirely.

Unfortunately in many cases updating the DRM isn't an option; StarForce, for instance, only provides Windows 7 drivers for versions 5.5 and above. If you're lucky it might still be sold on Steam or the like (with a newer/different DRM), but apart from that the "unofficial" route may be your best bet since by this time the developer/publisher either doesn't care or doesn't exist.

Not suprising if you give a shiat about your computer (most don't).
