Well, I started thinking "conspiracy theory"... maybe nVidia allow the problem to persist so that they can keep sales of their high-end cards going. Then I realised that this was codswallop...

I downloaded their release-notes for 53.03 drivers and sure enough they do address Maya 5.0 issues with the GeForce cards as they solved an issue: "Hardware Render shadows are drawn as squares instead of circles". But the viewport refresh problem is not mentioned; even in their list of unresolved issues.

So I think that we should start hounding them about it. All us FX5700 owners should send emails to the manafacturers of our respective cards and draw attention to the problem.

Here's some support email addresses for some of the big companies....

Leadtek: support@leadtek.com
Prolink/Pixelview: tec@prolink-usa.com

Pny: I had no luck finding a support address for them, if you know, please let me know.

Abit: technical@abit-usa.com

Albatron: support@albatronusa.com

Asus: tsd@asus.com

Gainward: support@gainwardusa.com

MSI: Again no luck with an email addy - you can go to MSI.com and submit a request by form

I've already sent an email to Pro-Link and would encourage you to do the same.
