Advanced Member ggaliens Posted June 8, 2010 Advanced Member Report Share Posted June 8, 2010 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. Quote Link to comment Share on other sites More sharing options...
Advanced Member ggaliens Posted June 8, 2010 Author Advanced Member Report Share Posted June 8, 2010 Hmmm ... Also ... using DirectX version of Simple 3DCoat. Cuda complained about old Nvidia drivers and I was not able to updated those drivers yet. Quote Link to comment Share on other sites More sharing options...

Taros Posted June 8, 2010 Report Share Posted June 8, 2010 3DC renders using GPUs, not CPU. Exactly. Quote Link to comment Share on other sites More sharing options...
Advanced Member ggaliens Posted June 8, 2010 Author Advanced Member Report Share Posted June 8, 2010 So you are saying that the render happens entirely on the GPU ... or mostly ??? My GPU is pretty lame, maybe. Quote Link to comment Share on other sites More sharing options...
Advanced Member ggaliens Posted June 8, 2010 Author Advanced Member Report Share Posted June 8, 2010 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.

Advanced Member ggaliens Posted June 8, 2010 Author Advanced Member Report Share Posted June 8, 2010 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.

Advanced Member mocaw Posted June 16, 2010 Advanced Member Report Share Posted June 16, 2010 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.: http://www.newegg.com/Product/Product.aspx?Item=N82E16814500138&cm_re=GeForce_GT_240-_-14-500-138-_-Product 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. -g Quote Link to comment Share on other sites More sharing options...
