ATI Graphics Ultra Plus
The Graphics Ultra Plus provided up to 1024 x 768 in 65,536 colours, or True Color (16.7M colours) at 800 x 600 resolution. Like the ATi Graphics Ultra, it came with a bus mouse port and was bundled with a 3-button 'inport' mouse.

In the Media
"Both the ATI Graphics Ultra Plus and ATI Graphics Ultra Pro share virtually the same physical design, save for the type of on-board display memory. With 2MB of VRAM the Pro is priced at $799, while the Plus, with 2 MB of DRAM, list for $499. In addition, the Pro offers a maximum noninterlaced resolution of 1,280-by-1,024 pixels, while the Plus's display tops out at 1,280-by-1,024 interlaced.The heart of both adapters is ATI's Mach 32 controller, a 32-bit accelerator that handles 64-bit instructions internally and includes a BitBlt engine, a 64-by-64 pixel hardware cursor, accelerated line draws, area fills, and a hardware cache.
Both of these adapters racked up impressive Windows test scores, with the Pro model pulling slightly ahead of the Plus with a Super VGA score of 6.42 megapixels per second (versus the Plus's 6.39). They also performed solidly in DOS, falling in the high side of the range for accelerator chips.
...the Plus exhibited none of the problems that plagued the Pro version. The Plus model did not include the memory-aperture feature and handily navigated all of the PC Labs' tests. Furthermore, Windows performance in high-color modes showed negligible degradation; the Plus turned in a WinMark test score of 5.69 megapixels per second - faster than most accelerators using only 256 colors.
Even without the bugs in the Graphics Ultra Pro, the Plus offers a better value for most buyers. Unless you absolutely need 1,280-by-1,024 noninterlaced resolution, the $300 savings is worth the slight decrease in performance, and Windows users shouldn't detect any difference between the two models.
As a rule, boards that used a given processor tended to have similar scores. The Pycon WinJet Edge, with C&T's 82C481 and Wingine chips, edged out the others on WinMark performance. Close behind were the two ATI boards, which used the ATI Mach32 chip; these were followed closely by the S3 801-based boards (the NDI Volante Warp10 and the STB PowerGraph X-24). Among boards using a given chip, the vendor's optimization techniques for its Windows drivers contribute most to performance differences."
