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. 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. This creates obvious color banding on low resolution textures viewed up close. It was also seen on Intel motherboards, as recently as , and was still used in for server motherboards. Rage IIc also seems to be the only R2 chip with fully asynchronous chip and memory frequency. To my knowledge Rage II did not get any better than this.

Same features, same image quality, as can be seen in the gallery. None of the advantages of abp Rage IIc can help it challenge any high performance architecture, so I put it against last Virge in disguise.
There are tweakers with sliders that should help with this issue sacrificing some performance, but I couldn’t achieve any change. Also depth buffer never delivered improved performance, so it is unlikely there is any z-compare rejection of pixels.
It turned out R2c has the same memory clock wall as R3- after MHz it gives up.

Thus the improvement over first Rage II comes down only to more memory. So I have nothing much to talk about, gallery is at your disposal anyway. As a low-power solution with capable 2D-acceleration, the chip was used on many low-end graphics cards.
Yet the driver is not preferring format, there is no speed improvement anyway. This late chip was very similar to the Rage II and supported the same application coding. This time the architecture was definitely up to date with all of the critical 3d features working.

It fixed the Battlezone issues at least. It took many years but final drivers are definitely good.

The chip was basically a die-shrunk Rage Prooptimized to be very inexpensive for solutions where only basic graphics output was necessary. Archived from the original on This will limit number of tests but never mind, better to have casual card ag rarely used exception.
Driver selected VT3 string, interesting I did some feature tests on VT4 in Tomb Raider 2. Considering how many boards shipped with only two megabytes of memory, it is welcome addition nonetheless. Upon closer look the bilinear filter is really cheap, just like first Rage showed. Rage II in person I bought this board with four memory chips in hope it is 4 MB, but it seems only way to get first Rage II with such capacity is through cards with memory expansion module.
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. 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.

But for the time Rage II line gained big market share among 3d accelerators. Experience As you will see in the performance summary improvements in the 3d architecture are not to be seen in real games.
From now on Rage chips carried new A3D logo, to show how serious is the new trend. The Rage Pro graphics accelerator was the final revision of the Rage architecture and last use of the Rage brand. Despite the poor introduction, the name Rage Pro Turbo stuck, and eventually ATI was able to release updated versions of afp driver which granted a visible performance increase in games, however this was still not enough to garner much interest from PC enthusiasts.
More promising feature could be texture compression technique with two to four times compression ratio, but by this ATi understood less exciting palletized textures.
As for driver bugs, I found only one serious, objects are disappearing in Battlezone. It is the successor to the Mach series of 2D accelerators. Similarly to Laguna3D all members of Rage II family suffers from perspective problems, some surfaces are just wavy instead of straight.
With memory bandwidth and sufficient capacity to allocate, true color rendering is a possibility. Xti, in addition to its early lack of OpenGL support, hurt sales for what was touted to be a solid gaming solution.
