[QUOTE=coolcolors;2552161]And did you try those games on another similiar computer to see what happens?? That is another way to test what might be causing the problem. Also I wouldn’t recommend using ALT-TAB as you might cause other problems you didn’t forsee coming. That key function should only be used for switching apps not swithing games as those games are running with all resources and doing so is like kicking it out and asking it to go back to fast mode. And it might bulk at that command function.[/QUOTE]
Thank you for reply
Under all games in XP 32 bit I think ALT-TAB work well. Windows 7 is the problem so far.
I have swapped a GTX 285 and GTX 460 between 2 different machine, as well have installed Windows XP 32 bit, Windows XP 64 bit and Windows 7 64 bit on the main GTX 460 machine (has intel 6 core processor). So far, Windows XP 64 bit is most problematic with drivers for other parts of system. It only patch to SP2 and I do not think I have available 64 bit drivers for all the new hardware for XP 64 bit.
I have all drivers for XP 32 bit and Windows 7 64 bit and the display problems are in Windows 7 not XP 32 bit so far.
I purchase the new system with Windows 7 64 bit and 12 gig of RAM so I could do much multi-tasking, including games. This was the main purpose. I do VirtualBox a lot on it but also run games to examine performance of components.
New system has Intel i7-980X Extreme, 12 gig of 1600 memory and Windows 7 Professional 64 bit with GTX eVGA Superclock 1 gig GTX 460 with 256 bit data path. It should be able to handle anything thrown at it I had hoped but there is combination of new hardware card (GTX 460) and what seem buggy Windows 7 driver for that card that are behind much of problem. Dirt2 is not most stable of game though either. But it also cause problem with Command and Conquer 3, which has never had any problem on any system I run before. It has been very stable game with never any display glitch before Windows 7 and GTX 460.
I may have bought card too soon and should have got established card instead? GTX 480 was big and loud so I thought of GTX 460. I wonder if GTX 480 would have less of problems with Windows 7?
