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. Windows 95 and Mac OS were not supported. 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. Most important was z-buffering implemented in hardware, as it became requirement for many Direct3D games. 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.

Initial versions relied on standard graphics memory configurations: Rage II in person I bought this board with four memory chips in hope it is 4 MB, rae it seems only way to get first Rage II with such capacity is through cards with memory expansion module. It took many years but final drivers are definitely good.

Again and better Autumn came and before anyone could yet realize first Rage will have miserable Direct3D compatibility, ATI unveiled second chip 3c the line. It was also seen on Intel motherboards, as recently asand was still used in for server motherboards. ATi also kept on missing opportunity to implemented vertex specular highlights under Direct3d, despite having the feature in their proprietary CIF.
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. Current technologies and software.
This, in addition to its early lack of OpenGL support, hurt sales for what was touted to be a solid gaming solution. Despite the poor introduction, the name Rage Pro Turbo stuck, and eventually ATI was able to release updated versions of the driver which granted a visible performance increase in games, however 3r was still not enough to garner much interest from PC enthusiasts.
For 3D Charger 4 MB of memory became standard and the card has good compatibility, avoiding problems until new generations of games in Experience 3d gaming with mere 2 MB is very limiting even if the chip was powerful. On top of that AGP 1x interface became an option, but without any advanced features.
Experience As you will see in the performance summary improvements in the 3d architecture are not to be seen in real games. Archived copy as title Pages using deprecated image syntax Commons category link is locally defined.
ATI RAGE IIC graphics card – RAGE IIC – 4 MB Overview – CNET
It fixed the Battlezone issues at least. This late chip was very similar to the Rage II and supported the same application coding. 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.
It seems despite die shrink ATI did not made any architectural advancements, pic least not in 3d. Autumn came and before anyone could yet realize first Rage will have miserable Direct3D compatibility, ATI unveiled second chip of the line. The texture mapping is just slow, unable to show better rates than three clocks per pcu, even at the simplest of scenarios.
It offered Filtered Ratiometric Expansionwhich automatically adjusted images to full-screen size.
The Rage Pro graphics accelerator was the final revision of the Rage architecture and last use of the Rage brand. Soon the competition in value segment got too tough. Needless to say 32 bit frame-buffer color with so little memory, even if well implemented, is out of question.
As for driver bugs, I found only one serious, objects are disappearing in Battlezone. I did some feature tests on VT4 in Tomb Raider 2. There are tweakers with sliders that should help with this issue sacrificing some performance, but I couldn’t achieve any change.

In reality, early versions of the new driver only delivered increased performance in benchmarks such as Ziff-Davis ‘ 3D Winbench 98 and Final Reality. It integrated a low-voltage differential signaling LVDS transmitter for notebook LCDs and advanced power management block-by-block power control. Almost every version of Rage was used in mobile applications, but there were also some 3f versions of these chips which were optimized for this.
