Tyger most people have same problems or 1 or 2 may get something else, now after install patch 2.1 had probs with p6 from p7 patch.
Reinstalled windows and put p6 back on with 3rd patch and p7 no patch, p6 runs fast though p7 has same probs without patches but set up scene in p6.
Now graphics cards can affect some programs and you have to go into the cards settings, just like on my p4 2.6 with ati 256 mg 1 gb 2100 can run Rome total war no probs.
But on my dual core amd 4200 with galaxy 7600gs and 1 gb 4200 program ran slow as buggery even with in game all options taken to low, so with the higher end nvidia cards a right buggery.
I had to go into the graphic cards settings and didn't have add rome exe was their all ready and i had to change cards settings for game by turning every thing off, and game runs faster.
Some problems can be caused by a graphics card but most are the fault of the programers and 1 thing software houses hate is if their was bad press about thier program.
Just imagine if at Olympics or world cup a competitor talking in front of 5 billion people said e-frontier and poser 7 bugged crap, e-frontier would have to release a statement as they would panic like crazy, the 1 thing software hoses fear is a major Internet campaign against any of their goods if faulty.
Though Microsoft it never harms them as if the zlob Trojan or another nasty program hits through I.E 7 and screws your registry, you either have to manually clean the registry or purchase a 3rd party program to do it.
Microsoft don't even bother to release a fix for you, just like 1 our pc magazines pointed out a security firm detected a hack couple hours after it hit web that exploited I.E 7, Microsoft were warned but as usual they took 8 days to release a fix.
I never use I.E unless having to access microsoft updates as i use FireFox only.
