It was ATI’s first dual texturing renderer, in that it could output two pixels per clock two pixel pipelines.
ATI 3D Rage IIC AGP
To my knowledge Rage II did not get any better than this. Most important was z-buffering implemented in hardware, as it became requirement for many Direct3D games. There are tweakers with sliders that should help with this issue sacrificing some performance, but I couldn’t achieve any change. Perspective correction and 32 bit depth and even Ahp have little impact, but bilinear filtering higher than desirable performance drop.

It integrated a low-voltage differential signaling LVDS transmitter for notebook LCDs and advanced power management block-by-block power control. Autumn came and before anyone could yet realize first Rage will have miserable Direct3D compatibility, ATI unveiled second chip of the line.
In other projects Wikimedia Commons. But for the time Rage II line gained big market share 3x 3d accelerators. For 3D Charger 4 MB of memory became standard and the card has good compatibility, avoiding problems until new generations of games in Sgp some bugs and simplifications hold image quality back.
With clocks almost identical to my vanilla Rage II it should demonstrate how additional memory helps. In reality, early versions of the new driver only ahp increased performance in benchmarks such as Ziff-Davis apg 3D Winbench 98 and Final Reality. This, in addition to its early lack of OpenGL support, hurt sales for what was touted to be a solid gaming solution.
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. It seems despite die shrink ATI did not made any architectural advancements, at least not in 3d. Similarly to Laguna3D all members of Rage II family suffers from perspective problems, some surfaces rge just wavy instead of straight. It took many years but final drivers are definitely good.
Only vertex fogging is performed rather slowly and often incompatible with transparent surfaces. Despite the poor introduction, the name Rage Pro Turbo stuck, and eventually ATI was able to release updated versions of agpp driver which granted a visible performance increase in games, however this was still not enough to garner much interest from PC enthusiasts.
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. 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. Experience As you will see in the performance summary improvements in the 3d architecture are not to be seen in real games.

It was up to Rage Pro to move ATi into higher class 3d gaming. From now on Rage chips carried new A3D logo, to show how serious is the new trend. Reported chip clock is 75 MHz, but that is wrong without a doubt.
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. Not because of lack of memory, this is true for all Rage II cards reviewed.
More promising feature could be texture compression technique with two to four times compression ratio, but by this ATi understood less 3dd palletized textures. There is one suspicious image quality issue, textures often seem to have reduced color range. The Rage Pro graphics accelerator was the final revision of the Rage architecture and last use of the Rage brand.
