Maybe a dumb question here, but nobody here even seems to have heard of Weitek boards for use with Autocad. I always thought that Weitek boards were gave Cadd apps a big performance boost, above and beyond an 80×87 chip. If these boards do help, anybody know how much they would increase performace relative to and 80×87 and what sort of street prices the boards go for? Thanks Allan

Allan: Weitek makes actual coprocessor integrated circuits – not boards. AutoCAD uses rather random mathematics, and then only about 15% of the time. Turns out that a Weitek would not improve the program's performance much, and because of this, AutoCAD does not include the necessary code to use one. In the future, some extensions to AutoCAD, such as AME, might use a Weitek chip. But don't buy one in anticipation of that. Evan

Evan, Let's not all be one-track regarding Weitek. They are also manufacturing display accelerator chips and are probably going to offer their own board based on this. Perhaps the gentleman was referring to these. Kevin Krell – Computer Support Associates

Evan, Actually, Weitek is into graphics controllers these days. We even did their Acad drivers. Their 5086 and 5186 are VGAs with hardware bitblt and linedraw. They are marketing them just like everyone else these days, as "Windows Accelerators". Brad Ek [Panacea Inc.]

Actually, to add to Brad's comment, Weitek announced the "Weitek Power For Windows" graphics board at COMDEX. It's based on the W5086 controller, and should be available shortly. Jake

Allan: AutoCAD doesn't even support the Weitek, so it would be money down the drain. According to the programmers, AutoCAD doesn't spend that much of its time doing floating point operations, so there's no compelling reason to support special coprocessors like the Weitek. 3D Studio is another story entirely, though. – Mark M.

Thanks to both of you! And now for the next question – can you tell us more about 3D Studio? Allan

Allan: I can't tell you much about 3D Studio, but if you saunter over to the ASOFT forum, you'll meet plenty of people there who can. – Mark M.

OK, will check it out Thanks Allan
