Sure. Sorry about leaving possible helpful information.
I'm using CS6 latest update. 22.214.171.124
Windows 7 latest updates.
Everything is working fine, Im just curious as to why my GPU information is only showing 2GB available when it should be 4GB. And if there is something that I should be doing to let After Effects use all available memory. Here is what is copied from my GPU information:
Fast Draft: Available Texture Memory: 1024.00 MB Ray-tracing: GPU
Vendor: NVIDIA Corporation Device: GeForce GTX 680/PCIe/SSE2 Version: 3.0.0 Total Memory: 1.95 GB Shader Model: 4.0 or later
Driver Version: 4.2 Devices: 2 (GeForce GTX 680, GeForce GTX 680) Current Usable Memory: 1.79 GB (at application launch) Maximum Usable Memory: 2.00 GB
I think you misunderstand how this works. SLI doesn't double the memory as effectively each card still uses its own buffers to do it's thing and the same is true for most CUDA/OptiX operations. Each card still has its own processing to do, those frameworks are merely a way of coordinating them. So in effect there may be the same redundant data loaded on each card because it is required to achieve the performance. Hence, since this is doesn't do anything that would allow you to laod more, the driver returns the value as if this were just one card and handles the rest by himself. That's also excplained somewhere on the NVidia pages, BTW.
