This creates obvious color banding on low resolution textures viewed up close. It was ATI’s first dual texturing renderer, in that it could output two pixels per clock two pixel pipelines. It fixed the Battlezone issues at least. ATi also kept on missing opportunity to implemented vertex specular highlights under Direct3d, despite having the feature in their proprietary CIF. More promising feature could be texture compression technique with two to four times compression ratio, but by this ATi understood less exciting palletized textures.

From now on Rage chips carried new A3D logo, to show how serious is the new trend. And Rage II ain’t some speedster. It was ATI’s first dual texturing renderer, in that it could output two pixels per clock two pixel pipelines.
From Wikipedia, the free encyclopedia.
Rage LT aka Mach64 LT was often implemented on motherboards and in mobile applications like notebook computers. Rage IIc also seems to be the only R2 chip with fully asynchronous chip and memory frequency. I did some feature tests on VT4 in Tomb Raider 2.
Windows 95 and Mac OS were not supported. Perspective correction and 32 bit depth and even Z-buffering have little impact, but bilinear filtering higher than desirable performance drop. Rxge memory bandwidth and sufficient capacity to allocate, true color rendering is a possibility.

Views Read Edit View history. This late chip was very similar to the Rage II and supported the same application coding.
NT put them both rags the AGP bus and switched between them, and so the board could only raage as a single Rage Rxge with the performance rave a Rage Fury card. However some bugs and simplifications hold image quality back.
Come to think of it how many small triangles were in old games? Even if these features were “free”, Rage II performance would be far from best. This, in addition to its early lack of OpenGL support, hurt sales for what was touted to be a solid gaming solution. In other projects Wikimedia Commons. All 3d primitives from points to quadrilaterals are supported. Archived from the original on This time the architecture was definitely up to date with all of the critical 3d features working.
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. There is one suspicious image quality issue, textures often seem to have reduced color range.

Similarly to Laguna3D all members of Rage II family suffers from perspective problems, some surfaces are just wavy instead of straight. Same features, same image quality, as can be seen in the gallery. It fixed the Battlezone issues at least. Autumn came and before anyone could yet realize first Sti will have miserable Direct3D compatibility, ATI unveiled second chip of the line.

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 integrated a low-voltage differential signaling LVDS transmitter for notebook LCDs and advanced power management block-by-block power control.
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. But for the time Rage II line gained big market share among 3d accelerators.
