Experience As you will see in the performance summary improvements in the 3d architecture are not to be seen in real games. Reported chip clock is 75 MHz, but that is wrong without a doubt. The chip was basically a die-shrunk Rage Pro , optimized to be very inexpensive for solutions where only basic graphics output was necessary. Blending unit looks flexible enough for any mode early Direct3d apps could throw at it. They were ATI’s first graphics solutions to carry the Mobility moniker.

From now on Rage chips carried new A3D logo, to show how serious is the new trend. Not because of lack of memory, this is true for all Rage II cards reviewed. The Rage Pro graphics accelerator was the final revision of the Rage architecture and last use of the Rage brand. It was ATI’s first dual texturing renderer, in that it could output two pixels per clock two pixel pipelines.
Archived from the original on Announced performance was 26 million perspectively correct texture mapped pixels per second. Needless to say 32 bit frame-buffer color with so little memory, even if well implemented, is out of question. It took many years but final drivers are definitely good. Current technologies and software.
As for driver bugs, I found only one serious, objects are disappearing d3 Battlezone. It was up to Rage Pro to move ATi into higher class 3d gaming. This is not much of surprise from a chip without texture caching, pvi despite this optimization in synthetic tests the performance drop of bilinear filtering remains ici big.
For it’s time it is quite feature rich and can draw nice pictures, unless one nasty bug kicks in. Overall While ATI had a horrible Windows driver reputation since Mach64, and the packages have scary high amount of files, my test system was stable and everything went as it should. Windows 95 and Mac OS were not 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.
All 3d primitives from points to quadrilaterals are supported. This late chip was very similar to the Rage II and supported the same application coding. And Rage II ain’t some speedster. Upon closer look the bilinear filter is really cheap, just like first Rage showed. Considering how many boards shipped with only two megabytes of memory, it is welcome addition nonetheless.
Come to think of it how many small triangles were in old games?
3D Rage II family review (DVD, VT4, IIc)
Experience 3d gaming with mere 2 MB is very limiting even if the chip was powerful. It scored with imperfect, but well chosen feature set including all important blending modes. It turned out R2c has the same memory clock wall as R3- after MHz it gives up. In other projects Wikimedia Commons.
In reality, early versions of the new driver only delivered increased performance in benchmarks such as Ziff-Davis ‘ 3D Winbench 98 and Final Reality. Even if these features were “free”, Rage II performance would be far from best.
On top of that AGP 1x interface became an option, but without any advanced features. 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.
It is the successor to the Mach series of 2D accelerators. In games, performance actually suffered.
It seems despite die shrink ATI wti not made any architectural advancements, at least not in 3d. Initial versions relied on standard graphics memory configurations:
