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. This creates obvious color banding on low resolution textures viewed up close. Same features, same image quality, as can be seen in the gallery. Similarly to Laguna3D all members of Rage II family suffers from perspective problems, some surfaces are just wavy instead of straight. All 3d primitives from points to quadrilaterals are supported. 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. 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.

This is not much of surprise from a iicc without texture caching, still despite this optimization in synthetic tests the performance drop of bilinear filtering remains rather big. So I have nothing much to talk about, gallery is at your disposal anyway.

Views Read Edit View history. It turned out R2c has the same memory clock wall as R3- after MHz it gives up. 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. NT put them both on the AGP bus and switched between sti, and so the board could only operate as a single Rage Pro with the performance of a Rage Fury card.

This time the architecture was definitely up to date with all of the critical 3d features working. It fixed the Battlezone issues at least. Archived copy as title Pages ikc deprecated image syntax Commons category link is locally defined. Announced performance was 26 million perspectively correct texture mapped pixels per second. Archived from the original on Soon ai competition in value segment got too tough.
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. There are tweakers with sliders that should help with this issue sacrificing some performance, but I couldn’t achieve any change.
Retrieved from ” https: In other projects Wikimedia Commons. Initial versions relied on standard graphics memory configurations: The Rage Pro graphics accelerator was the final revision of the Rage architecture and last use of the Rage brand.
This creates obvious color banding on low resolution textures viewed up close. From now on Rage chips carried new A3D logo, to show how serious is the new trend. As for driver bugs, I found only one serious, objects are disappearing in Battlezone.
More promising feature could be texture compression technique with two to four times compression ratio, but by this ATi understood less exciting palletized textures. This will limit number of tests but never mind, better to have casual 3dd than rarely used exception.
It was up to Rage Pro to move ATi into higher class 3d gaming. Blending unit looks flexible enough for any mode early Direct3d apps could throw at it. Rage LT aka Mach64 LT was often implemented on motherboards and in mobile applications like notebook computers. 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 this was still not enough to garner much interest from PC enthusiasts.
Considering how many boards shipped rzge only two megabytes of memory, it is welcome addition nonetheless. Autumn came and before anyone could yet realize first Rage will have miserable Direct3D compatibility, ATI unveiled second chip of the line.
Driver selected VT3 string, interesting Rage 3r 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.

It integrated a low-voltage differential signaling LVDS transmitter for notebook LCDs and advanced power management block-by-block power control. This late chip was very similar to the Rage II and supported the same application coding. As the name says, AFR renders each frame on an independent graphics processor. Thus the improvement over first Rage II comes down only to more memory. Rage IIc also seems to be the only R2 chip with fully asynchronous chip and memory frequency.
