In the case of game bugs I would speculate that 95% of bugs (at least) are the game developers fault. I remember interning at a small game studio, and the game would occasionally crash, but only on ATI system and the crash would occur inside the ATI driver DLL. So the devs blamed it as an ATI driver bug. I spent some time going over it with the debugger, and it turns out that they would occasionally do something that the OpenGL spec explicitly forbids (an empty glBegin()/glEnd() block iirc). I'm assuming that ATI didn't do checks for invalid inputs in the interest of performance, which was something that the spec allows for them to do. I imagine that this sort of bug is not uncommon.
After all, all ATI and Nvidia can reasonably be expected to do is follow the API specs to the letter - which is the entire point of the spec. I find it amazing that the two companies are going far beyond that and doing bug fixing for other companies games.
Now, in this particular case it seems to be some sort of incompatibility, but I do believe that it is likely a similar type of problem as one side not following the spec to the letter.
This is very enlightening, thank you. Same thing happened with Second Life. NVIDIA cards had a bug where textures would render black. LL blamed NVIDIA's drivers, when it fact it was a problem with SL.
Anyway I was curious if this error 43 incompatible display device was a problem only on Nvidia type motherboards. I asked over at the ATI forum if anyone was having this problem that had an AMD board. The answer is YES so apparently this problem has nothing to do with Nvidia or AMD type boards. Actually it seems like a lot of people are fixing this problem by reinstalling the operating system. Im just not prepared to do that at this time.

yep, same result here. the tv is now detecting the signal as a PC, it used to be detected as 16:9 1080p/60.
now the only Picture Mode profiles are Text or Video. All the video processing is disabled. The Home -> Screen menu does show the signal correctly as 1920x1080/60Hz.
ATI must have changed the way the signal is output.
i ran a small test in Crysis, im pretty sure i was GPU limited which could be one of the reason i didnt see a real improvement in FPS
but i was in 1920x1080 ALL Very High except Motion Blur at Medium, no AA, no AF.
my avg fps was about the same, but i gained about 3 fps on the max end, which would be from looking at the sky which would be more CPU limited than GPU doing that, which i did on both the 9.1 and 9.2.

Same crap Error 43 incompatible display device and only one of the GPUs is enabled. Had to go back to 8.11.
Thanks ATI............
Never had problems like this with Nvidia SLI........
Your issues probably doesn't have anything to do with the GFX card. I would suggest you look into the MB instead to solve your issues.
You can read up on this error from even older cards and drivers:
http://support.ati.com/ics/support/default.asp?deptID=894&task=knowledge&questionID=25973
Nvidia chipsets are not famous for their compatibility and stability (I've had a few Nvidia MB's myself too). Thats why people loved that SLI could be run on newer intel chipsets.
I'm running a 4870X2 on Vista 64, 4GB memory, asus P5Q, Q9550 CPU and GFX drivers have been a painless installation from 8.10 to 9.2. No Error 43 and both GPU's are enabled.
Thank Nvidia for your issues, not ATI.
Uh the problem hasnt turned out to be the Nividia board..............this is still an unknown.
And Im still praising Nvida for their drivers because I have never has problems with the SLI portion not working with new drivers. I have had Nvidia drivers not work well with certain games and have had to roll back to older drivers.
I've never had big problems with either. Nvidia has given me more headaches than ATi. Good luck, to each his own.
Wow, with all the risks of having problems, I think I'll stick with 8.12 for now.
Is power play fixed on these?
Windows 7 64bit no problems with 9.2 on my 4870x2.
