Yet the driver is not preferring format, there is no speed improvement anyway. I did some feature tests on VT4 in Tomb Raider 2. It offered Filtered Ratiometric Expansion , which automatically adjusted images to full-screen size. The chip was basically a die-shrunk Rage Pro , optimized to be very inexpensive for solutions where only basic graphics output was necessary. Archived from the original on

Archived from the original on Soon the competition in value segment got too tough. Upon closer look the bilinear filter is really cheap, just like first Rage showed. There is one suspicious image quality issue, textures often ap to have reduced color range. This, in addition to its early lack of OpenGL support, hurt sales for what was touted to be a solid gaming solution.
ATI 3D Rage IIC AGP
All 3d primitives from points to quadrilaterals are supported. Announced performance was 26 million perspectively correct texture mapped pixels per second.
The texture mapping is just slow, unable to show better rates than three clocks per sample, even at the simplest of scenarios. Current technologies and software. As the name says, AFR renders each frame on an independent graphics processor. Windows 95 and Mac OS were not supported. Reported chip clock is 75 MHz, but that is wrong without a doubt. And Rage II agpp some speedster.
It seems despite die shrink ATI did not made any architectural advancements, at least not in 3d. It fixed the Battlezone issues at least. Even if these features were “free”, Rage II performance would be far from best. It is the successor to the Zti series of 2D accelerators.
Come to think of it how many small triangles were in old games? Again and better Autumn came and before anyone could yet realize first Rage will have miserable Direct3D compatibility, ATI unveiled second chip of the line.

For 3D Charger 4 MB of memory became standard and the card has good compatibility, avoiding problems until new generations of games in It turned out R2c has the abp memory clock wall as R3- after MHz it gives up.
Yet the driver is not preferring format, there is no speed improvement anyway.
Almost every version of Rage was used in mobile applications, but there were also some special versions of these chips which were optimized for this.
In games, performance actually suffered. This will limit number of tests but never mind, better to have casual card than rarely used exception. Considering how many boards shipped with only two megabytes of memory, it is welcome addition nonetheless.
Driver selected VT3 string, interesting ATi also kept on missing opportunity to implemented vertex specular highlights ag; Direct3d, despite having the feature in their proprietary CIF. Aside from the VR chip’s lower price-point, the main difference was that the former was a full bit design, while the VR, still a bit processor internally, used a bit external memory interface.
Number of games that can be actually run is of course limited, so gallery is not very big. As for driver bugs, I found only one serious, objects are disappearing in Battlezone. Blending unit looks flexible enough for any mode 3e Direct3d apps could throw at it. Also depth buffer never delivered improved performance, so it is unlikely there is any z-compare rejection of pixels. I did some feature tests on VT4 in Tomb Raider 2.
