CPU only 4%-10% during render turntable
Does this make sense ???

I have a Quad core Athlon.
HP Pavillion
8GB RAM
GeForce 9100 Integrated Graphics
Windows 64bit.
64 bit 3DCoat


Rendering 360 frames in sequence.

System feels really sluggish during render even though task
mgr reports low CPU utilization.

Could be a memory/bus bottleneck or something ???

Need some hints on what to expect.

Got a 15 Million voxel sculpture rendering.

Hmmm ...


Also ... using DirectX version of Simple 3DCoat.
Cuda complained about old Nvidia drivers and I was not able to updated
those drivers yet.

3DC renders using GPUs, not CPU.

Exactly.

So you are saying that the render happens entirely on the GPU ... or mostly ???

My GPU is pretty lame, maybe.

How do I tally up whether my PC can handle addition of dedicated GPU on card, or not ???

I'm thinking in terms of powersupply. UGH. I bet it does need new power supply.
Hope I can make that happen. I'm not much of a hardware guy.

As a rule of thumb for recently discussed CUDA cards (Nvidea): min 550W for GTX 470 and min 600W for GTX 480. These are power hungry and fewer GPUs would require less.

OK ... I upgraded from a 300 Watt PSU to a 500 W PSU .

I hope that's enough. The GeForce 8500GT supposedly consumes
about 180W according to some tests and reports. Ad one of it's
requirements waws listed as 300 W PSU or 350 PSU if newer machine.
But that was prob written a while ago.

Like I said ... I hope 500 W is a big nough jump, even if I decide to
try a better card in future.

At least I off the integrated chip. Not seeing a HUGE Boost even though on card and
with CUDA now. But I trust I haver done the right thing regardless.

Hopefully some new sculptures to show soon.

This all depends on what you need, but if you go for cards that were as powerful as the top cards a year or two ago, but the chips have been shrunk down and made to conserve energy. You can get a performance upgrade that uses very few watts, maybe even less power than your current card. Some of these GT 240 cards like this one only need a 300W+ power supply pending your not running a bunch of drives etc.:

You would probably see a big improvement even with this card over your old one since it has 96 cores- no it's not going to be a GTX 275 and up type of improvement, but you probably will not need to cut your case to fit it, buy a new power supply, or add system fans to your case AND you'll save a huge amount of money to boot.

I'm looking into these cards as an option since I don't need to sculpt a bagillion voxels etc.- just 2-3 million and I'd be fine.
