I was referring to environment maps in the ray-traced 3D renderer. The VRAM on multiple GPUs is used for this purpose. There's a little idiosyncrasy in that if you have multiple GPUs with
different amounts of VRAM, After Effects treats them like they all have the same amount (the smallest amount among them). From: After
Effects Mail List [mailto:AE-List@media-motion.tv] On Behalf Of Hillary Knox So you're saying that there would be a benefit to having a Titan or other lots-of-VRAM GPU, even if you aren't using CUDA-enabled features? In AE, is that VRAM cumulative across multiple GPUs?

When you have little VRAM, there's a lot of time wasted uploading and clearing textures to and from the VRAM; with a lot of VRAM, more can be held on the GPU at once.
