"NVidia test?"

[xbdestroya]

Ok, well I just unlocked the 8 pixel pipes and 2 masked vertex pipes on a recent 6800 LE purchase. I get no artifacts gaming or in 3DMark2001 (will try 2003 tonight). But I've also heard references to the 'NVidia test' as being a little more stringent in seeing if an unlock/overclock is stable/successful. Any ideas what exactly this is, or where I can download it?

just run rthdribl with all options on at the highest possible resolution you can and if no artifacts show up, you're fine. rthdribl stresses yuor video card like yuo wouldnt believe.

Hmmm... thanks for the heads up!

never heard of rthdribl before...
try 3dmark05 and run it about 3 times in a row

What is rthdribl ?

Rthdribl is a "Real-time High Dynamic Range Image-Based Lighting" demo. DirectX(R) 9.0 high-precision texture formats and version-2.0 of Pixel Shader represent real-time true HDR rendering.

Technical features of the demo are:

* True HDR (High-Dynamic Range) Rendering
* IBL (Image-Based Lighting)
* Glare Generation (Afterimage, Bloom, Halo, Ghost, and Star)
* Automatic Exposure Adjustment
* Iris shaped Depth of Field blur
* Realistic Motion Blur
* FSAA (Full-Scene Anti-Alias)
* Fresnel Effect (Specular Reflectance) etc.

The Glare, Motion Blur, Fresnel Reflection and Depth of Field effects work properly by rendering with the HDR (see Fig.1-3).
Fig.4 shows the "Automatic Exposure Adjustment".
And Fig.5 images are are variety of the Glare patterns that can be generated in the demo.

These effects are still expensive for real-time rendering like games, but will hopefully be of practical use in the near future.
Enjoy the future real-time rendering!

it's a nice program. the reason i recommend this is that it stresses your gpu memory and core even more than 3dmark05 when all settings are turned up. I use it to test my radeon 9800pro ocs. run it for 8hours overnight ot make sure i've got a stable, permanant oc.

BTW, HDR looks a lot better in this progrma than say AOE3.
My 9800pro struggles to hold 20fps at 10x7 all settings default. when i drop to 2xMSAA(4x default, 16x max), it gos up to 27fps or so.
