It took many years but final drivers are definitely good. Same features, same image quality, as can be seen in the gallery. It scored with imperfect, but well chosen feature set including all important blending modes. Most important was z-buffering implemented in hardware, as it became requirement for many Direct3D games. It turned out R2c has the same memory clock wall as R3- after MHz it gives up.

Only vertex fogging is performed rather slowly and often incompatible with transparent surfaces. 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.
With memory bandwidth and sufficient capacity to allocate, true color rendering is a possibility. It is the successor to the Mach series of 2D accelerators. Maybe newer drivers broke compatibility with the tweak. Initial versions relied iid standard graphics memory configurations: Rage IIc also seems to be the only R2 chip with fully asynchronous chip and memory frequency.
Driver selected VT3 string, interesting For 3D Charger 4 MB of memory became standard and the card has good compatibility, avoiding problems until new generations of games in There is quite recent xti set for this pair of chips, but opposed to 2.
All 3d primitives from points to quadrilaterals are supported. Yet the driver is not preferring format, there is no speed improvement anyway. In reality, early versions of the new driver only delivered increased performance in benchmarks such as Ziff-Davis ‘ 3D Winbench 98 and Final Reality.

Rage LT aka Mach64 LT was often implemented on motherboards and in mobile applications like notebook computers. With clocks almost identical to my vanilla Rage II it should demonstrate how additional memory helps. It was also seen on Intel motherboards, as recently asand was still used in for server motherboards. From now on Rage chips carried new A3D logo, to show how serious is the new trend. It scored with imperfect, but well chosen feature set including all important blending modes.
It was up to Rage Pro to move ATi into higher class 3d gaming. Also depth buffer never delivered improved performance, so it is unlikely there is any d3 rejection of pixels.
Same features, same image quality, as can be seen in ahi gallery. It turned out R2c has the same memory clock wall as R3- after MHz it gives up.
Thus the improvement over first Rage II comes down only to more memory.

As a low-power solution with capable 2D-acceleration, the chip was used on many low-end graphics cards. For it’s time it is quite feature rich and can draw nice pictures, unless one nasty bug kicks in.
Experience As you will see in the performance summary improvements in the 3d architecture are not to be seen in real games. The Rage Pro graphics accelerator was the final revision of the Rage architecture and last use of the Rage brand. Oic for the time Rage II line gained big market share among ato accelerators.

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. They were Ragw first graphics solutions to carry the Mobility moniker.
