How could one not mention the Turbo disaster in a Rage Pro article. ATI entered like a graphics giant with more than 1, employees and during the year topped number of 3d chips sold, many of them integrated on motherboards. Nevertheless, sales were going strong and R3 architecture was to be found in newer and actually updated chips. Peak processing rate is 1. Initial versions relied on standard graphics memory configurations: This page was last edited on 7 June , at

In other projects Wikimedia Commons. Developers were not pleased. If it was design choice, the motivation behind it is a mystery to me. Nevertheless, sales were going strong and R3 architecture was to be found in newer and actually updated chips.
The former being easier to fix, Radeon entered the market in the middle of as a first direct competition to Nvidia’s TnL chips. 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.
The amount is about the same as for Rage II, but this time is less expected since Rage Pro was supposed to have high quality texturing engine and “free” trilinear filter will not compensate for such deficiencies. As the name says, AFR renders each frame on an independent graphics processor.
As a low-power solution with capable 2D-acceleration, the chip was used on many low-end graphics cards.
ATI’s effort to bite into professional market is also clear from addition of edge anti-aliasing.
Between companies designing high performance 3d accelerators ATI was among last to deliver dual pipeline architecture. The chip was basically a die-shrunk Rage Prooptimized to be very inexpensive for solutions where only basic graphics output was necessary. In games, performance actually suffered. Rage Pro has double the amount of gradients over Rage II and it is enough to not be perceived at first look, but still is far from proper filtering.
Who knows when, but the day will come when 3d accelerator as we use it will be unknown to gamers. ATi also never really excelled in 16 bit quality, instead they went for big true color leap ahead with next architecture.
They were ATI’s first graphics solutions to carry the Mobility moniker. ATI dragged this filter into next gen Rage as well and fortunately for them almost nobody noticed. Which brings me to gaming experience of R3 cards. Windows 95 and Mac OS were not supported.
It offered Filtered Ratiometric Expansionwhich automatically adjusted images to full-screen size. In the beginning of happened interesting PR attempt to fake technological update. ATI showed cleverly balanced chip and in rapidly consolidated market suddenly became the only “real” threat to what was shaping like Nvidia’s complete domination. The chip should support also WRAM with external MHz ramdac to exploit them at high resolutions, but I am not aware of any card taking advantage of that.
Current technologies and software. And as an integrated graphics for servers it went on almost forever.

Quake 3 even sgp special rendering path doing this filtering in software, but in some scenarios like with teleports the Rage Pro has to do the job on its own and leave some non-interpolated texel blocks on screen. Actually, after two freezes doing only timedemos I am not sure if they ever really got it stable. This, in addition to its early lack of OpenGL support, hurt sales for what was touted to be a solid gaming solution.
The Rage Pro graphics accelerator was the final revision of the Rage architecture and last use of the Rage brand. But when it arrived at the end of the year in the form of Rageit also demonstrated very advanced design with “full speed” 32 bit depth rendering.
