Gregory, a 486/66 that works correctly will render scenes at almost double the speed of a 33. Something is seriously wrong with it. What memory manager are you using on that machine? – G

Both machines use QEMM ver 6.02. But why should all of the "speed" numbers bee so different?

You really should upgrade to the latest flavor of Qemm 7.x There is obviously something wrong with your system/configuration. I have NEVER seen a 66 render the same speed as a 33. Or maybe you've got a well engineered 33 motherboard, and a poorly engineered 66 motherboard. I've got two AMI EISA 66's that render 20% faster than the other NICE ISA 66.

John, PMJI. I just noticed you mentioned the NICE board. I haven't been able to solve what I thought was an easy problem. I have the NICE SUPER EISA with 256MB. I've talked to MS, QUARTERDECK, …ETC. The CMOS message says 64MB and ADDITIONAL 192MB AVAILABLE. Dos and qemm only sees 64MB until I use HIMEM.YSY /EISA, then it recognizes 89MB. Wierd. NICE said that the board was properly set up as long as I was getting the correct ADDITIONAL memory message. I thought that there were a lot more 3DS'rs with over 64MB configurations. Can you help?

Kurt, The only person I know of here which is using more than 64 is Paul Lind. I recall he was running 128 Mb. Maybe he'll poke his head in and give you some insight. The other person who might know is Gus Grubba. I'd be curious to know how you resolve this. Its hard to imagine that Microsoft couldn't help you but then I've had similar experiences. You might try the ACAD forum. There are some serious power users over there as well. -JE

I don't run more than 36 megs on my machines (AMI & Nice MB's, will take 256, but I haven't had $$$ or reason to do that, yet). My first guess is that the NICE board has a defect. I'd try the memory on another board before moving on. I know Paul Lind used to, and Matthew Freeman still does run machines with more than 128megs. They may have an idea of what's going on. Still, it really seems like the board's the problem, I'd eliminate that possibility first. good luck, John Tissavary (La Luna cie)

John, Thanks for the suggestion. I did have some luck figuring this out. With HIMEM.SYS /EISA enabled and QEMM disabled, 3DS sees the whole deal. Dos MEM.EXE would only report 64MB but when I run 3DS it sees it all. I wasted alot of time with MEM. MSD did however report the correct memory size. I saw some threads here about disabling the video shadowram and doing the shadow with QEMM. I'll give that a try. For now, 3DS (and I) are very happy. Thanks -KM

Glad you got it sorted out. Very strange that QEMM would not recognize all the memory. John Tissavary (La Luna cie)
