SPEC’s ViewPerf - Lightscape-03
The Lightscape Visualization System from Discreet Logic combines proprietary radiosity algorithms with a physically based lighting interface. A sample screen shot is shown:
There are four tests specified by the viewset that represent the most common operations performed by the Lightscape Visualization System:

The SPEC Lightscape-03 viewset tests were performed at 1280x1024, truecolor, Vsync off. The Lightscape profile was selected for the ELSA driver and the 3Dlabs drivers; the NVIDIA 3.65 driver did not have any such tuning options

The GLoria II (Quadro) and
GeForce equipped cards scored about the same and were about 38% faster than
the next best card the GVX1-AGP. The GVX1-PCI was a lot slower than the AGP
version of the same card. The VX1 and TNT2Ultra cards performed the slowest
on this test. Test data posted at the SPEC site shows that only the higher
end NT workstation systems, which use the Intergraph Wildcat 4110 and NEC TE4E
graphic systems, score better (~40%) than the GLoria II (Quadro) or GeForce
cards.
