T&L Emulation
Several tests from the 3DMark2001 suite can be employed to test the geometry processing speed of the graphics card, particularly the tests with one and eight light sources as well as the point sprites test.
The GammaChrome S18 performs like the RADEON X600 PRO in the single-light-source test, lagging somewhat farther behind in higher resolutions.
The card from S3 is ahead of the RADEON X600 PRO in the test with eight light sources ?the GammaChrome’s four vertex processors contribute to this performance. The absolute winner is the GeForce 6600 since its core contains special units for an efficient execution of older T&L-using applications.
The Point Sprites test doesn’t only load the vertex processors, but also requires the graphics card to have a high texturing speed and a fast memory subsystem. These units of the GammaChrome S18 work fine, but the drivers from S3 are imperfect as yet. So, the new card delivers the performance of the RADEON X300.
