There are tweakers with sliders that should help with this issue sacrificing some performance, but I couldn't achieve any change.
This, in addition to its early lack of OpenGL support, hurt sales for what was touted to be a solid gaming solution. Number of games that can rate actually run is of course limited, so gallery is not very big.

With clocks almost identical to my vanilla Rage II it should demonstrate how additional memory helps. There is one suspicious image quality issue, textures often seem to rgae reduced color range.
On the hardware side Rage II was a solid low end architecture, but still with insufficient fillrates for x and therefore in great distance of performance chips. It scored with imperfect, but well chosen feature set including all important blending modes. This will limit number of tests but never mind, better to have casual card than rarely used exception. Needless to say 32 bit frame-buffer color with so little memory, even if well implemented, is out of question. And Rage II ain't some speedster.
It was ATI's first dual texturing renderer, in that it could output two pixels per clock two pixel pipelines.

This is not much of surprise from a chip without texture caching, still despite this optimization in synthetic tests the performance drop of bilinear filtering remains rather big.
Thus the improvement over first Rage II comes down only to more d3. This page was last edited on 7 Juneat The Rage Pro graphics accelerator was the final revision of the Rage ap and last use of the Rage brand. This late chip was very similar to the Rage II and supported the same application coding.

ATi also kept on missing opportunity to implemented vertex specular highlights under Direct3d, despite having the feature in their proprietary CIF. Initial 3f relied on standard graphics memory configurations: For 3D Charger 4 MB of memory became standard and the card has good compatibility, avoiding problems until new generations of games in This creates obvious color banding on low resolution textures viewed up close.
I did some feature tests on VT4 in Tomb Raider 2. Soon the competition in value segment got too tough. Also depth buffer never delivered improved performance, so it is unlikely there is any z-compare rejection of pixels. Windows 95 and Mac OS were not supported.
The processor was known for its well-performing bit color mode, but also its poorly dithered bit mode; strangely, the RAGE was not much faster in bit color despite the lower bandwidth requirements. Most important was rafe implemented in hardware, as it became requirement for many Direct3D games.

Experience As you will see in the performance summary improvements in the 3d architecture are not to be seen in real games. The chip was basically a die-shrunk Rage Prooptimized to be very inexpensive for solutions where only basic graphics output was necessary. It turned out R2c has the same memory clock wall as R3- after MHz it gives up. It seems despite die shrink ATI did not made any architectural advancements, at least not in 3d. Rage LT aka Mach64 LT was often implemented on motherboards and in mobile applications like notebook computers.
Only vertex fogging is performed rather slowly and often incompatible with transparent surfaces.
It was also seen on Intel motherboards, arge recently asand was still used in for server motherboards. To my knowledge Rage II did not get any better than this. Not because of lack of memory, this is true for all Rage II cards reviewed.
It was up to Rage Pro to move ATi into higher class 3d gaming.
