Yet the driver is not preferring format, there is no speed improvement anyway. I did some feature tests on VT4 in Tomb Raider 2. Windows 95 and Mac OS were not supported. Only vertex fogging is performed rather slowly and often incompatible with transparent surfaces. 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.

With memory bandwidth and sufficient capacity to allocate, true color rendering is a possibility. Maybe newer drivers broke compatibility with the tweak. It fixed the Battlezone issues at least.
Views Read Edit View history. With clocks almost identical to my vanilla Rage II it should demonstrate how additional memory helps. It seems despite die shrink ATI did not made any architectural advancements, at least not in 3d.
All 3d primitives from points to quadrilaterals are supported. Considering how many boards shipped with only two megabytes of memory, it is welcome addition nonetheless. They were ATI’s first graphics solutions to carry the Mobility moniker.
However some bugs and simplifications hold image quality back. But for the time Rage II line gained big market share among 3d accelerators. Windows 95 and Mac OS were not supported.
ATI 3D Rage IIC AGP
It is the successor to the Mach series of 2D accelerators. It turned out R2c has the same memory clock wall as R3- after MHz it gives up. On top of that AGP 1x interface became an option, but without any advanced ragwiic. Experience 3d gaming with mere 2 MB is very limiting even if the chip was powerful. This page was last edited on 7 Juneat The texture mapping rageiiic just slow, unable to show better rates than three clocks per sample, even at the simplest of scenarios.
ATI 3D Rage IIC PCI
For it’s time it is quite feature rich and can draw nice pictures, unless one nasty bug kicks in. The chip was basically a die-shrunk Rage Prooptimized to be very inexpensive for solutions where only basic graphics output was necessary.
For 3D Charger 4 MB of memory became standard and the card has good compatibility, avoiding problems until new generations of games in Autumn came and before anyone could yet realize first Rage will have miserable Direct3D compatibility, ATI unveiled second chip of the line. This, in addition to its early lack of OpenGL support, hurt sales for what was touted to be a solid gaming solution.
Needless to say 32 bit frame-buffer color with so little memory, even if well implemented, is out afi question. 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. 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.
Yet the driver is not preferring format, there is no speed improvement anyway.

Reported chip clock is 75 MHz, but that is wrong without a doubt. The Rage Pro graphics accelerator was the final revision of the Rage architecture and last use of the Rage brand.
Come to think of it how many small triangles were in old games? It took many years but final drivers are definitely good. In other projects Wikimedia Commons. Rage IIc also seems to be the only R2 chip with fully asynchronous chip and memory frequency. Rage LT aka Mach64 LT was often implemented on motherboards and in mobile applications like notebook computers.
