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. With memory bandwidth and sufficient capacity to allocate, true color rendering is a possibility. Most important was z-buffering implemented in hardware, as it became requirement for many Direct3D games. Rage IIc also seems to be the only R2 chip with fully asynchronous chip and memory frequency. Driver selected VT3 string, interesting

ATI Rage IIC 3d AGP Video Card 109-49300-01
Yet the driver is not preferring format, there is no speed improvement anyway. Soon the competition in value segment got too tough. Considering full availability in Christmas season such figure was far from exciting.
Initial versions relied on standard graphics memory configurations: Experience As you will see in the performance summary improvements in the 3d architecture are not to be seen in real games. The chip was basically a die-shrunk Rage Prooptimized to be very inexpensive for solutions where only basic graphics output was necessary.
In reality, early versions of the new driver only delivered increased performance in benchmarks such as Ziff-Davis ‘ 3D Winbench 98 and Final Reality.
From Wikipedia, the free encyclopedia. This late chip was very similar to the Rage II and supported the same application coding. Autumn came and before anyone could yet realize first Rage will have miserable Direct3D compatibility, ATI unveiled second chip of the line.
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. Perspective correction and 32 bit depth and even Z-buffering have little impact, but bilinear filtering higher than desirable performance drop.
Maybe newer drivers broke compatibility with the tweak.
3D Rage II family review (DVD, VT4, IIc)
From now on Rage chips carried new A3D logo, to show how serious is the new trend. All 3d primitives from points to quadrilaterals are 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.
Number of games that can be actually run is of course limited, so gallery is not very big. It took tage years but final drivers are definitely good. However some bugs and simplifications hold image quality back. Most important was z-buffering implemented in hardware, as it became requirement for many Direct3D games.
For 3D Charger 4 MB of memory became standard and the card has good compatibility, avoiding problems until new generations of games in It integrated a low-voltage differential signaling LVDS transmitter for notebook LCDs and advanced power management block-by-block power control. It seems despite die shrink ATI did not made any architectural advancements, at rzge not in 3d.
There are tweakers with sliders that should help avp this issue sacrificing some performance, but I couldn’t achieve any change. The Rage Pro graphics accelerator was the final revision of the Rage architecture and last use of the Rage brand.
Not because of lack of memory, this is true for all Rage II cards reviewed.
ATI 3D Rage IIC AGP
Reported chip clock is 75 MHz, but that is wrong without a doubt. With clocks almost identical to my vanilla Rage II it should demonstrate how additional memory helps.
This will limit number of tests but never mind, better to have casual card than rarely used exception.
None of the advantages of my Rage IIc can help it challenge any high performance architecture, so I put it against last Virge in disguise. It was also seen on Intel motherboards, as recently asand was still used in for server motherboards.
