September'2001 3Digest:
NVIDIA Riva TNT
By Andrey Vorobiev
This chip is presented by Canopus Spectra 2500 16 MBytes, AGP videocard.
Features:
- NVIDIA Riva TNT chip, 90 MHz clock rate, 128-bit engine;
- 16 MBytes SDRAM memory in eight Hyundai 10ns microchips, 110 MHz clock
rate, 128-bit bus;
- Peak speed of scene drawing in multitexturing mode is 90 megapixels/sec
and 180 megatexels/sec.
Videocard doesn't tweak over standard due to slow memory and the graphic
core itself.
For the 20th of December'2000 the last driver version is NVIDIA - 6.49,
6.50.
You can see that 6.* drivers are better than 2.*, so you should use them
and all later versions. By the way Unreal looks awful in 32-bit color
with older drivers, so you should use 3.* and later versions, excluding
7.* versions. I want readers to note 7.* drivers, they are just "raw" and can't functions properly even on beta level. Quake3 and other OpenGL
applications doesn't run at all, and D3D games show big speed fall,
therefore all games were tested with 6.50 version.
There are not so many problems with 3D graphics. But trilinear approximation
instead of true trilinear filtering lowers the card's rating. Below
are shots taken on this card (to the left) and on NVIDIA GeForce2 GTS
(to the right).

This card has awful 2D quality. 800x600 gives you a chance of normal
work, and there are strong "soaping" effects in higher resolutions.
But 2D quality varies from card to card based on this chip. There are
some cards that show rather good 2D quality.
