Even if these features were “free”, Rage II performance would be far from best. Yet the driver is not preferring format, there is no speed improvement anyway. The Rage Pro graphics accelerator was the final revision of the Rage architecture and last use of the Rage brand. But for the time Rage II line gained big market share among 3d accelerators. In reality, early versions of the new driver only delivered increased performance in benchmarks such as Ziff-Davis ‘ 3D Winbench 98 and Final Reality. On top of that AGP 1x interface became an option, but without any advanced features. Windows 95 and Mac OS were not supported.

In games, performance actually suffered. They were ATI’s first graphics solutions to carry the Mobility moniker. It turned out R2c has the same memory clock wall as R3- after MHz it gives up.
Experience 3d gaming with mere 2 MB is very limiting even if the chip was powerful. Soon the competition in value segment got too tough. Number of games that can be actually run is of course limited, so gallery atk not very big. Overall While ATI had a horrible Windows driver reputation since Mach64, and the packages have scary high amount of files, my test system was stable and everything went as it should.
Rage IIc also seems to be the only R2 chip with fully asynchronous chip and memory frequency. 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 ari lower bandwidth requirements.
Reported chip clock is 75 MHz, but that is wrong without a doubt. Only vertex fogging is performed rather slowly and often incompatible with transparent surfaces. Driver selected VT3 string, interesting More promising feature could be texture compression technique with two ragejic four times compression ratio, but by this ATi understood less exciting palletized textures. 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.
And Rage II ain’t some speedster.

Archived from the original on 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 was up to Rage Pro to move ATi into higher class 3d gaming. Maybe newer drivers broke compatibility with the tweak. On top of that AGP 1x interface became an option, but without any advanced features.
Again and better Autumn came and before anyone could yet ragieic first Rage will have miserable Direct3D compatibility, ATI unveiled second chip of the line.

But for the time Rage II line gained big market share among 3d accelerators. Considering how many boards shipped with only two megabytes of memory, it is welcome addition nonetheless. As the name says, AFR renders each frame on an independent graphics processor.
NT put them both on the AGP bus and switched between them, and so the board could only operate as a single Rage Pro with the performance of a Rage Fury card. I did some feature tests on VT4 in Tomb Raider 2.

Needless to say 32 bit frame-buffer color with so little memory, even if well implemented, is out of question. The chip was basically a die-shrunk Rage Prooptimized to be very inexpensive for solutions where only basic graphics output was necessary.
Perspective correction and 32 bit depth and even Z-buffering have little impact, but bilinear filtering higher than desirable performance drop. This will limit number of tests but never mind, better to have casual card than rarely used exception.
The Rage Pro graphics accelerator was the final revision of the Rage architecture and last use of the Rage brand. Archived copy as title Pages using deprecated image syntax Commons category link is locally defined.

Considering full availability in Christmas season such figure was far from exciting. Most important xti z-buffering implemented in hardware, as it became requirement for many Direct3D games.
However some bugs and simplifications hold image quality back. It offered Filtered Ratiometric Expansionwhich automatically adjusted images to full-screen size. The texture mapping is just slow, unable to show better rates than three clocks per sample, even at the simplest of scenarios.
