Nvidia Tech Demos Are Stuttering

[DefRef]

I tried to run Luna, Nalu and Dusk and then run at about 2 FPS when they ran like glass before. Anyone else seeing this? Clocked down to 570/875 from 570/900 with no change and played the Black & White 2 demo for an hour tonight without a problem.

The 84.21 drivers have very poor OpenGL performance so that would explain the issue if the tech demos run under said API.

The answer to your problem lies here.

I have the FW84.21 WHQL drivers installed on my system, and the Mad Mod Mike demo runs really well. My videocard is an XFX 7900GT EE.

Wooooo, I just ran the Luna demo and that one was really cool. Good FPS, too.

Weird. I uninstalled the Nvidia drivers and put on the TRU set and when I started Luna and Nalu, they were just as slow and choppy as ever, but after a bit, they smoothed out and ran fine. FEAR got CRAZY faster, but Dusk had anamolies.

Just use the 84.20's, the 84.21's appear to suffer issues the 84.20's don't. I recommend the Extreme-G version linked above.

And just to clairify, there is no diffierece between the 84.21's and the 84.20 besides the WHQL thing.
(yet the 84.20 works better?)

I haven't personally tried out 84.21, but I have no OpenGL issues with 84.20.

Do the XTG drivers help with 6 series cards and FEAR or are they only better for 7 series cards?

 

[Gstanfor]

Yes, the GF6 series receive a FEAR boost with the 84.20's.
