Rage IIc also seems to be the only R2 chip with fully asynchronous chip and memory frequency. Thus the improvement over first Rage II comes down only to more memory. Even if these features were “free”, Rage II performance would be far from best. As for driver bugs, I found only one serious, objects are disappearing in Battlezone. On top of that AGP 1x interface became an option, but without any advanced features. Driver selected VT3 string, interesting

Rage LT aka Mach64 LT was often implemented on motherboards and in mobile applications like notebook computers.

For 3D Charger 4 MB of memory became standard rzge the card has good compatibility, avoiding problems until new generations of games in The Rage Pro graphics accelerator was the final revision of tage Rage architecture and last use of the Rage brand. 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.
However some bugs and simplifications hold image quality back. Experience As you will see in the performance summary improvements in the 3d architecture are not to be seen in real games. Experience 3d gaming with mere 2 MB is very limiting even if the chip was powerful.
Reported chip clock is 75 MHz, but that is wrong without a doubt. Also depth buffer never delivered improved performance, so it is unlikely there is any z-compare rejection of pixels. This page was last edited on 7 Juneat Maybe newer drivers broke compatibility with 3dd tweak.
It is the successor to the Mach series of 2D accelerators. 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. This creates obvious color banding on low resolution textures viewed atj close. Come to think of it how many small triangles were in old games? It was up to Rage Pro to move ATi into higher class 3d gaming. Yet the driver is not preferring format, there is no speed improvement anyway. 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.
As the name says, AFR renders each frame on an independent graphics processor. The texture mapping is just slow, unable to show better atl than three clocks per sample, even at the simplest of scenarios. More promising feature could be texture compression technique with two to four times compression ratio, but by fage ATi understood less exciting palletized textures.

It scored with imperfect, but well chosen feature set including all important blending modes. Considering how many boards shipped with only two megabytes of memory, it is welcome rrage nonetheless. 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.
Soon the competition in value segment got too tough. Even if these features were “free”, Rage II performance would be far from best. Windows 95 and Mac OS were not supported.
As a low-power solution with capable 2D-acceleration, the chip was used on many low-end graphics cards. As for driver bugs, I found only one serious, objects are disappearing in Battlezone.
