Hi All: Does anyone have any experience upgrading from a 486 to a Pentium Overdrive processor with regard to 3DS performance? I have a 486DX/2 now and am contemplating the upgrade to the new 63MHz Overdrive. I have heard that the faster FPU makes a big difference in the regular Pentium processors compared to the 486. In fact, since 3DS makes frequent use of the FPU, it is said that moving to a (60MHz) Pentium can give a minimum 4X speed improvement. Does this match the experience of people on this forum? I have heard that the faster FPU is also present in the Overdrive. Thanks in advance for any help, MattMan.

Matthew, a Pentium will render about twice as fast as a 486, clock speed for clock speed. That's because 3ds is not optimized for the Pentium – actually, I know of no software that is. Maybe the next version …. who knows? I'd buy the overdrive chip from a place that allowed 30-day money-back guarantee. That way if it fails to perform you could replace it with a new motherboard and CPU, which might not be much more money any way.

MattMan: I don't have the 63mhz chip you have described but the comparison I am able to make between a 486/66 and a 586/66 seems to give me a 100% speed increase. I doubt that the 63mhz chip could be 4x as fast as the 486/66, my experience suggests 2x. If anyone can verify that 4x is the answer I'll be snapping up one of those new chips immediately. Bob
