I am going to buy a P90. Does anyone have any suggestions? I will be using it for rendering in 3ds and other Adesk apps. The ZEOS seems to be one of the better contenders. Nonetheless, I have heard that it can only handle 2 full length cards and even with some of the smaller cards if there is any overlap there is a conflict with the P90 voltage dropper card. Also, it has onboard scsi-II. I am not sure if this would be better than PCI SCSI-II or not? I would be really interested in knowing if PCI SCSI-II is desireable or not? Is anyone real happy with any of the P90's out there? Thanks, Stephen

call me. i do 3d animation/multimedia production. Use pentium 60/66/90's. Can be a problem if you're not carefull. Some SCSI bugs on the 90's…. IPAS and 90's? Hmm… heard rumors but our board runs great. I also am lead tech. You've got the name, the # is 214-233-8052

Stephen, >> I am going to buy a P90. Does anyone have any suggestions? << I'd look into the Micron. The price/performance and flexibility in terms of configuration not to mention compatibility with Autodesk products makes it a good buy IMO. -JE

I just read the latest PC magazine (V.13 N.12) review p.165 on 90 Mhz pentiums. I was suprized to find that they gave Micron one of the _lowest_ bang for the buck ratings in their graph on p. 168. Actually, the graph shows the Micron as being good in price and bad in performance. This is nuts. Their performance ratings on p. 175 place the Micron as probably the _best_ one. Look at the Winstones, Disk Winmarks, Processor, Disk, and Graphics charts. Micron is the best, or nearly the best, in all of them. The only shortcomings were Video and DOSMarks. The textual review (p. 184) does at least give the Micron an Editors choice, but fails to mention the highly affordable upgrade options (see p. 104). No, I do not have a financial interest in Micron. But, I think I just talked myself into buying one. Now where is that credit card . . . 🙂 — James — MAP —

James, I think reviews often don't tell the whole story, and sometimes you have to be able to read between the lines as you did. These reviews seem to be getting more and more biased, with evaluations based on questionable parameters. For instance it is well know that some display card developers optimize their chips to pass Winmark tests, where in fact in real world application they are slower than other display cards who ratings don't appear as good. Which is why you need independent reviews, not reviews sponsored by the magazine in which the product is advertised. Also what is good for animation may not rate as high in Windows tests. I think the Micron is a good system for the money. I think however if money was not a consideration I would probably get a DEC Alpha. But I see the Micron as a solid stable workhorse and very suitable to the task. -JE

If you're at all interested in PC's, don't read PC Magazine. I think they have the worst reporting of any journal I've ever read. John Tissavary (LUNA cie)

I used to read PC Magazine from cover to cover for years. In the last few years I have noticed an extreme political bias in support of Microsoft. It is still a good magazine for the utilites and new product bulletins. Still, if you want to see a textbook case of bias, read Windows Magazine. At least PC Magazine offers some real-world data to support their claims. In Windows Magazine, I have seen product comparisons with claims founded on a shadey rumor and presented as scripture. — James — MAP —

John, I really like what the micron has to offer. Micron has a 512k Cache upgrade for $200. Is it worth it? Do Acad/3ds/AApro benifit by having the extra 256k of cache? Stephen
#106735From: John EllisJun 9, 1994 3:55 PM
Stephen, Basically the cache upgrade will help you most if you have more than 32 MB of RAM installed. As Micron is a RAM producer the price is probably pretty reasonalbe. I'd have to check on it, which I will do if you are seriously contemplating purchasing it. Let me know. -JE
#106888From: Stephen GrisezJun 10, 1994 9:25 AM
John, I will purchace the cpu with 32meg of ram. I will then steel 32meg of ram from my 486/66 and upgrade the new 90mhz to 64meg. I have been rendering shopping centers with and my models are between 10 and 13.5 meg. One of the main reasons for looking at the MICRON is that there are 6 slots for ram. 64meg is not going to last very long… I know I will need more. There will always be 64+ in this cpu. Therefore, will the extra 256 Cache help on this type of work? Do you have any ideas about percentage increase in rendering time? Thanks, Stephen
#106895From: John EllisJun 10, 1994 10:02 AM
Stephen, You might want to consider getting the Optimize IPAS with models of 10 to 13.5 Mb sizes. It really does a nice job minimizing vertices and faces and can help significantly increase rendering times. >> There will always be 64+ in the CPU. << The extra 256 cache will definitely help. In theory you'd like to have 256k cache for every 32 Mb of RAM. Its hard to say exactly how much of a performance increase you'll get but between 5 and 10% would not be unreasonable, which can really add up over a few hundred frames. To get a feel for it you can turn off the cache in your 66 and time a render, then turn it back on again. I take it that you are already using 72 pin simms in your 66? If not you will not be able to use the RAM from your 66 in your P90. Something to be aware of. Micron's pricing on ram is very competive BTW. -JE
#106954From: Stephen GrisezJun 10, 1994 2:31 PM
John, I wish I knew about MICRON's pricing on ram before. I am aware of there prices, very reanonable. I could have saved a lot of money on ram. It won't be the last time that ignorance "of a better deal" bites me. Oh well. Yes, all of my 16meg simms are 72pin. Yes Thanks for the input no the cache. Stephen
#106981From: John EllisJun 10, 1994 4:41 PM
Stephen, Sounds like you've got a good plan and have the details worked out. Very wise! <g> I think you'll be happy with your new system and I expect you'll get good support from Micron as they like to tought the fact that they maitain compatibility with Autodesk products. -JE
#107553From: Stephen GrisezJun 13, 1994 11:44 PM
John, I don't think I could get much simpler. I also don't have the optimize IPAS. I'm not sure it would do much to a simple diciduous tree made from Silicon Garden. The trees that I am using are only about 80k but I have 200+ of them. I could send you one of my trees if you want to give it a try. Stephen
#107588From: John EllisJun 14, 1994 3:05 AM
Stephen, I'm afraid I missed or just spaced your message. Sorry about that. You were mentioning that you had 80k trees but 200+ of them, and I'm not sure what it is in reference to. I have optimized trees and it does help. FWIW I have become an instant convert to Optimize. I now have 3 favorite modeling tools, Optimize, Displace, and Fractilize. In this game of PC's vs workstations which many people have told me is more a matter of bus speed than processing power every face/vertice you can get rid of helps. I've been working on a project which before optimizing was 112k faces and after optimizing I got it down to 55k. Rendering times decreased by 40-45%. That in my estimation is a massive savings in time and money. More valuable than upgrading to a pentium, not that you can't benefit by the processing power but that benefit is wasted without totally efficient modeling etc. I'm guessing but I would suspect you could cut your trees poly's by 20% without a reduction in coverage. I hope this answer's your question, if not fill me in and I'll try again. I'd be happy to optimize one of your trees for you so that you could compare. -JE
#107595From: Kurt McKeeverJun 14, 1994 4:05 AM
I could be wrong, but aren't the SG trees already optimized (if you have the optimize button on)? I guess it might optimize some on morphable trees and plants. I'll have to test both. Kurt
#107653From: John EllisJun 14, 1994 12:33 PM
Kurt, You're probably right, I've got an older version of SG and haven't seen and didn't realise that was what the upgrade entailed. Thanks for "optimizing" my awareness. <g> -JE
#107687From: Stephen GrisezJun 14, 1994 4:02 PM
John, I will send you a couple of trees. Heck, I would like to send you my whole 13+ meg file <g>. Ok, I'll just send the trees. Stephen
#107735From: John EllisJun 14, 1994 8:27 PM
>> I will send you a couple of trees. << I checked out your trees and they seem to be constructed with the newer version of SG, and so are therefore fully optimized. I ran the normal optimization value of 2.00 which produced the same result in terms of faces and vertices. Just for the heck of it I tried a value of 12.00 which is fairly high in terms of reducing faces etc. and the result was the same. I haven't worked with the later release of SG but it appears to not only produce good looking vegetation but also fully optimized. So I guess that Pentium is going to have its work cut out for it. <g> If its any consolation you would'nt have considered it even feasible to do what you're now attempting, to do a year ago. At least I wouldn't have. As I mentioned to Kurt McKeever, who pointed out that there was an optimization switch in SG, I wasn't aware of as I have an earlier release and just haven't gotten around to upgrading it. It seems to be doing its job very well. But there may be other things in your scene that could benefit from Optimize. -JE
#107839From: Stephen GrisezJun 15, 1994 10:35 AM
John, Yes, you are right, only a year ago 200+ deciduous, 100+ pines, a parking lot with striping, a "detailed outside" of a building, a couple of trucks, a pylon sign, other assorted things, and all in one model, was only in my dreams <g>. The trees are really what kill me. Right now trees are about 11 meg. The deciduous are the worst. I am doing my pine trees with 8 faces per tree, opacity and textrue maps. I am mostly satisfied with the results. Oh well, I guess I will have to buy another cpu. The story of my life <g>. Stephen I'm sure I will check out the optimize on the rest of my model sometime soon.
#106812From: John N. JordanJun 10, 1994 12:35 AM
Steven: I have a 486/66 from Micron, and have had absolutely zero problems for the 8 months I've had it. I'm seriously looking at (drooling over) the Pentuim 90 system they have- the one with 32MB ram and 1 gig drive. It's $5000. I've looked all around for better systems for less money, and haven't been able to find them. (I even have a friend that runs a computer store.) Most systems I've added up, containing 32MB ram, a good 17" monitor, PCI, SCSI-2 GIG drive, and at 90mhz are at least 500+ more. The only thing I'm not sure about is if there are any little conflicts with 3DS. Mabe Autodesk has one to test. If it runs 3ds bug free, get one. -but I'd want a MGA Impression PCI board- not an option I know about. (Mabe Autodesk will suggest it to them. I'd appreciate it.) JNJ
#106861From: John EllisJun 10, 1994 6:29 AM
John, The Micron P90 works very with 3DS. They also offer an MGA II card as an option. -JE
#106889From: Stephen GrisezJun 10, 1994 9:25 AM
John, I don't think the MGA Impression is an option with the MICRON. I may ask to get the CPU without a graphics card and then add it. What's the difference between the MGA Impression and the MGA II+ with 2meg? I hope it has AutoCAD drivers. Stephen
#107049From: John N. JordanJun 11, 1994 12:59 AM
>I don't think the MGA Impression is an option with the MICRON. I just called Micron today and left a message to someone I was transferred to. I said that since Micron is the supplier, and that there have been many people talking about Micron in this forum (and, I'm sure in other Adesk forums), I said they needed the Impression PCI. (for obvious reasons) Press this. ASK for it, and mabe they will carry it. I want a system from them, and also want the Impression.. and I'm sure there's more like us. So bug them enough and we'll probably get it. It's crazy to have to buy the stealth card, and then the impression, when all you want is the impression. They carry the MGA, they should carry the impression. Don't take no for an answer. <g> JNJ
#107058From: David StinnettJun 11, 1994 2:18 AM
>> the Impression PCI… FYI, there's no such thing. The MGA Impression is only available in ISA and VL bus models, and nothing yet exists for PCI that will support hardware shading (only the MGA ultima line is out for PCI, but it does not support 3d shading). I was told of an "Impression Pro PCI" in the works, but I don't know how soon that will be out, but when it does become available, I hope Pavel's IPAS previewers will run on it. David
#107154From: John N. JordanJun 11, 1994 3:50 PM
>> the Impression PCI… I thought someone (Ara?) saw one at Comdex, or some other show.. I figured it would be out now, or shortly. Mabe not, I guess. JNJ
#107181From: David StinnettJun 11, 1994 6:51 PM
It may have been announced or even shown at Comdex, but a rep over in the Matrox forum just told me it was "…in the works…", but he didn't give me a release date. So I suppose it's very possible it'll be out soon… but then again….?
#107275From: John N. JordanJun 12, 1994 2:29 PM
Thanks for the clarification. It'll be a little while until I get a system anyways. Just doing research now. I hope it's out by the time I get the Micron.
