RAM usage at 98% – something not right?
Hi guys-
I am encountering what I perceive as a problem, and can’t seem to find any answers online.
I have a city scene with a fly through- it’s right under 500,000 polygons, with 1300 materials/textures. When navigating, as well as rendering, my RAM is hitting the 99% mark almost all the time, making impossible to do ANYTHING other than just what C4D is doing at the time. (It’s hitting the 80ish mark before rendering- once I turn up AA to 4x, AO and GI using the IR cache, it pegs out to 99%, making the computer useless for anything else other than the render itself)
Is this normal? It seems a lot of people are cramming WAY more into their scene, and with less RAM. I guess I am trying to figure out A: what is Cinema packing into my RAM that is taking up 5.5 GBs, and B: would upgrading from 6 to 12GB be worth the investment?
I am mainly asking because I hate to drop the bucks on the RAM, only to find out this is out of the ordinary. I am used to C4D utilizing 100% CPU, but not my RAM as well…
Thanks for any input/suggestions!

are you using 64 bit OS/C4D? Do your 1300 materials use 1300 large images? Either way memory usage can be more than you expect and more memory would be good. I had 6 at home and at work and put an extra 8 in at home and now don’t have any troubles at home. (also running studio, 64 bit on Macs)

I am using 64 Win Ult.
The textures total about 260 MB. (they vary form 80k to a couple hundred k, each).
I found a great deal on another 6GB, so I went ahead and bit the bullet. Should be in by the end of the week, and I’ll update once I get it in and re-try this scene.
On a side note, while it didn’t fix my actual render issue with the RAM, I switched off OpenGL and it GREATLY increased my view port navigation. (I have 2 x EVGA GTX480s, so I thought the GPU may help…apparently not)
Thanks for the advice, Brian. I’ll let you know if it solves my issues.

OpenGL should be faster but you might be having driver issues, (and I have *no* idea if dual cards hurts or helps or doesn’t matter here) check out the driver thread on CGTalk https://forums.cgsociety.org/showthread.php?f=47&t=917277

That’s what I thought, too… I am going to re-install my drivers, and verify they are the latest certified, just to be sure. I did find it odd that, even if it’s only using 1 GPU, it was SO much slower than the CPU in the view port/navigation.
