I have been rendering 3D scenes with Maya, and I have noticed a sudden drop in productivity. I have 2 Dual Core Xeon 5070 cpus in the system in question. Before, when rendering, all 4 cores would render, using between 90-100% of processing power. I would check the Task Manager, just to verify this. But, lately, I've been working on a different scene, with a fraction of the geometry and lighting, and it seems it's only utilizing half of the power it should be using. It is staying near 50% usage, using half of each core's power. I checked the Affinity of Maya, and it is set to use all 4 cores (labeled as CPU 0, 1, 2, and 3). I set it's Priority to High, but it still doesn't help. Any help would be greatly appreciated!
