Hi, I just received Imagine 3.0 and I have a couple quick questions. First, was Imagine 3.0 compiled to take advantage of the Pentiums dual pipeline processing? Or will it take advantage of the Pentiums feature to increase rendering? Also will Imagine 3.0 be affected by the P90 fpu bug?

Mr. Payton Our system and the way it renders does not have to be compiled as you suggest, it rips on the pentium, Now as for the bug, I suppose it is possible that it could show up, but as of yet, we have several pentiums in house, we have not seen and record of this happening nor do I think that it will. We are checking into things to see if there is a problem, if there is one, you will, if you sent in your warranty card get a newsletter that will discuss this issue, if indeed it is an issue. BTW if you bought Imagine from us directly then you are on the list and will not have to worry about a warranty card. Enjoy Imagine and your new Pentium and dont put tooo much concern in to the possible problems with the CPU, I doubt that it will come up anytime soon. Mike

PMFJI, but re: pentium bug: I've rendered about 10,000 frames on a P5 in the last six months or so, and have not seen any evidence that Imagine is affected by the FDIV bug in the Pentium chip. I frequent the Dell user group, and am amazed at the way people are freaking out about this problem. Somebody came up with two seven digit numbers that, when divided and successively multiplied, came up with a wrong answer; the whole forum seemed to blow a collective gasket. I did some tests myself to try and find a number combination that would fail, and after a day or so of searching (and you can search a LOT of numbers on a P5-90) I gave up. I think Intel's "once in 27,000 years" comment is a bit irresponsible, but IMHO the Pentium FDIV bug shouldn't affect Imagine in any significant (or detectable) way, if at all.
