My computer gets slow after a lot of polygons. i need more ram?

[destro80]

Do you have Mac or PC?
Whats your video card?
Which OS?

But in any case for 3D you should have at least 1 gig of RAM.

[Nomi-Graphics]

just wondering how much ram i should have if im using cinema 4d... i have 512 mb of ram in my system and my system is an amd athlon 64 3000+ with chaintech mobo.. its a darn good system. but i open a model and make it editable to mess with polygons and things get almost too slow for my liking. will more ram (like say a gig or more) increase my computers ability to handle more polygons?

thanks for helpin

You are definitely low on ram for 3D work.

I would go at least a gig, if not two. Ram is cheap now, don't be afraid to go for as much as you can :)

And get a copy of c4D 64 bit since you have the system to run it on. :)

Cheers.

[williamsburroughs]

oops...sorry for the double post...the window didn't refesh. :eek:

[Bob3D]

I agree with Nomi Graphics. IMO 512Mb is a bit paltry nowadays regardless of what you're doing. You're strangling that CPU of yours (poor little thing)!

Do you not need 64 bit Windows to run C4D 64 bit? If that's the case it means spending money (I don't have any :sad: ) even though the C4D 64 bit upgrade is free. Anyway, I'm a bit worried about driver and other software issues running under 64 bit Windows. Please correct me if I'm wrong - if you can run 64 bit C4D under ordinary old Win XP then I'll be downloading it now. :curious:

Salvo errore you will need Winxp 64 to run c4d64.
Other programms may not run, so consider that if you have to fit it into a pipeline. Ihave heard for ex that quick time does not function yet under xp64.

[williamsburroughs]

Oh...sorry...i figured the vendor who sold you the machine offered a free/inexpensive upgrade path to the OS...anyhoo...you could always do a dual boot partition of it.

Tossing polys around like a cat with a mouse has always seemed cool to me. :)

Just get more ram...1gb + will free up some restrictions you are having.

Cheers.

Aw. Oh well, I'll wait then...

Yeah, and you have to get new drivers for all your stuff as well... I've heard availability of drivers is a *serious* issue at this point with xp64

thanks everyone. i have an Radion ATI 9600 XT and my OS is windows XP.. i have a copy of Windows XP 64 bit ed but I reinstalled regular XP after finding out that C4D wouldnt work with XP64 bit. lol! but since you mention that there is a free upgrade, i will try that out. very cool.

You cant dual boot XP and XP64 bit edition. tried it..results not good!

[c4dportal]

Dual boot works fine, especially if you have two partitions or two hd's with two drive letters.

More ram doesn't make your video card faster, so you'll still be having slowdowns when pushing around lots of polygons in the portview.

Dual booting win 32 and 64 has no issues at all, sounds like you fluffed it up somehow.

[Oli4D]

Yeah thats a RAM-Thing what you are talking about. Video-Card is also important (ATI 9600 is ok, could be better ;-) ), but if the computer gets slow when you have a complex mesh... it basicly a RAM thing. 512 is ok, but not good for 3D work. I would say 1024 would be "minimum" for complex meshes and high-res Textures. Depends on what you want to so.
If the rendering is slow, its a CPU thing :-).

I've the same problem with the attached object. (PIII 3.1ghz, 1gb RAM, GF 6800GT)

When i switch to a subdivision of 2, the system freezes and crashes.
There are about 15 objects in the hypernurbs-container.

You could move all the objects out from under the hypernurbs. Then set the hypernurbs subdivision to 2. Then move the objects back under the hypernurbs one by one. This should isolate which object is causing the crash.

[JamesMK]

And make sure you haven't accidently made nested hypernurbs inside other hypernurbs at some point. It's a fairly common mistake.

[Martin Kay]

Whilst 512Mb of ram isn't much these days, surely it'll surfice or not. Its unlikely that the guy has anywhere near 512Mb of mesh. Isn't the real problem with 'huge' polygon sets redraw time?

[Thalaxis]

I think you're right -- it sounds like an ATI OpenGL driver problem to me.

Dave, did you make sure that you have the most current ATI drivers? They have been making impressive improvements (still trailing nVidia's stability and performance, though).

It's a shame that ATI's OpenGL drivers are still so far behing nVidia's... ATI's OpenGL performance and stablity is miles behind their DirectX performance and stability.

This is the first thing to isolate. Is it the video card that's overloaded, or is he out of RAM.

Dave, next time you get a slowdown, have a look at the hard drive light on your case. If it stays on for more that about 10 seconds, you need more RAM. If the hard drive light isn't staying on, it's your video card that is overloaded. You can also tell if you need more RAM because once you run out, your whole computer will run slowly, not just Cinema 4D.

You can also tell if you need more RAM because once you run out, your whole computer will run slowly, not just Cinema 4D.

You can also press ctrl-alt-esc and click the performance tab, and see how much memory you're using, as well as how much virtual memory (and other little details like the number of page faults and that sort of thing).

In case anyone happens to be curious, the standard UNIX equivalent is top.

[dave247]

well as a cheap alternative, i jacked my page file up to 2 gigs on one of my other logical drives with a lot of free space. System seems to be diong fairly well especially if I keep the poly's low.
