What can it do? In following picture T stands for texturing, P for perspective correction, B for bilinear texture filter and Z is for Z-buffering. RV Radeon is a die shrink of R with some improvements. ATi calls it “Smoothvision”. Drivers vary in their behavior as well. The exception is of course special case of Su, and there the Rage also does not help the performance. Wonder if it helped somebody believe this is really a 3d accelerator.

AMD still produces graphics cards today. Like other chips from the first generation of texture mappers, it was a reputation destroyer rather than builder.

However, like the previous Rage chips, the Rage Pro cannot bilinear filter alpha textures, resulting in transparent textures still having a rough appearance.

ATi introduced a tessellation function called TruForm. ATI went through same pain like Nvidia and 3Dlabs did in This page was last modified on 17 Aprilat I even heard about single megabyte card, which would just scratch any hope for reasonable 3d. Introduced inthese Radeons added the “HD” prefix to their names.

This macy64 well with human vision and gives a tangible improvement to anti-aliasing quality. Despite video texturing support the Rage is not displaying them in Mortal Kombat. Fortunately for Ati, their marketing did not raise very high expectations to begin with. Yes, there is 32 mahc64 3d mode, but blending operations are causing color corruption in true color depth. Macn64 is a rename of Radeon LE.

For comparison there is again Virge 2 MB at resolution of x, highest possible without dropping textures. This was not an issue until about 2 years after launch when games started to outright require shader model 3.

Chroma key comparison for texture transparency works. The Radeon is a 4 pipeline design with 2 texture units per pipeline and operates at up to MHz, typically with synchronous core and RAM.

Limited feature set, especially failure to deliver DirectX compatible depth buffering, only meant that the 3D Rage was degraded into solid 2d card.

It supports 8-bit palettes for textures, helping to get away with small capacity. R has many improvements and noticeably better visual quality than ATI’s prior chips. Latest official drivers are used.

Anisotropic filtering is somewhat improved, with more levels supported, but is again very angle dependent and can not work with trilinear filtering. The VGA Wonder series added additional value with the inclusion of a bus mouse portwhich normally required the installation of a dedicated Microsoft Bus Mouse adapter. As a 3d accelerator first Rage proved quite useless.


However, there is a speed difference between disabled textures from start and failure to display them. The sticker was already there when I bought it. Given a chip clock of 44 MHz on my card, 3D Rage has peak fillrate of 22 million perspectively correct texture mapped pixels per second and perhaps can somehow achieve claimed K Gouraud shaded triangles per second geometry performance.

Bike shadows in Motoracer are simple rectangles. They are still shader model 2.

But I do not want such short articles, so I spent some time with Tomb Raider 2. There are many variations of this card. Summary What more to say. In ATI was a big graphics company with strong presence of various 2d accelerators build on mach64 architecture.

Introduced inthis is ATi’s Direct3D 9. I could not get any OpenGL title to work even with my wrappers.
