I upgraded my graphics card from a Leadtek Ti4200 AGP to an Albatron GF6600 GT AGP recently and I am experiencing graphical problems in games and some other non-3D screens.
For example, in GTA3 I get ghosting effects and the road markings are all screwed up, and on the title screen there are white blocks/lines over the GTA logo. In Max Payne 2, The intro movie has the same white blocks/lines and plays very slowly. In-game, there are problems with the lighting - instead of glare effects etc. from lamps, there are crazy white rectangles in the direction that the light is shining. Also, in MediaPortal (HTPC software) some of the graphics appear distorted with the same white blocks/lines (eg. the MP animation in the ProjectX skin, and the Weather icons) The card performs fine, no slowdown in-game, it just has these annoying glitches.
Because everything was working fine with the previous Ti4200 card, I sent the new card back. The vendor tested it by running it on 3dmark2005 for several hours, saying they found no problems (and demanded payment for their troubles :/ they didnt even try the games/apps I told them about!). I tried 3dmark2005 as soon as I got home, and found similar lighting problems as described in Max Payne 2.
What is the likely cause of these graphical problems? I have already tried the following steps:
* changing nvidia drivers (using the most recent at present, tried a couple of previous versions which made the graphic problems in MP2 worse)
* unplugging all devices in my system apart from one hard drive and the power connector going into the video card (I have a 350W Enermax power supply, power should not be a problem)
* running the Ti4200 gave none of these problems with the most recent nvidia drivers
I did have a Leadtek 5200 Ultra AGP in the PC but it died just after a year of age (the screen would go all crazy colors and the computer would lock up 2mins after booting, sometimes less) - not sure if that was due to the card or something else...
