This post is meant as a warning and a prompt.
NVidia's detonator 50 series drivers and gaming cards continue to be incompatible with Maya since they yield the dreaded viewport corruption that many have posted on these forums. I have been dealing with this issue for some time now and it has given me pause when thinking about future video card choices.
I am running a GeForce FX 5950 Ultra and am only able to use maya by installing the "Omega" install of 45.23 drivers at: http://www.omegacorner.com. This solves my problem but relies on the drivers being "spoofed" into thinking that the card is a 5900 Ultra. No word yet on whether later cards will work in this configuration.
For those of you considering new NVidia gaming cards for workstation use, seriously look at whether you can afford a pro DCC card like the Quadro FX. Knowing what I know now I would likely have spent the extra $500 for one of these cards.
Does anyone reading this know how to submit bugs reports to NVidia? I know that they are disinclined from making their less expensive cards work with Maya, but perhaps this incompatibility is an unnecessary result of a DX9 tweak that can be undone with no penalty.
