I have 2 GEforce GTX 680's installed with 2 GB of VRAM each. In the Adobe docs, it says....
"If you have multiple GPUs installed, the GPU-accelerated ray-traced 3D renderer will use the CUDA cores on all of them, as long as they are of the same CUDA compute level. (See the technical specifications of your GPU for its CUDA compute level.) After Effects will also use all of the VRAM on the installed GPUs, with the caveat that both cards will be treated as if they each have the amount of VRAM on the card with the lesser amount of VRAM."
But in the After Effects preferences, it sees the 2 cards but only saying 2 GB of RAM is available. Anyone have any idea? I tried this with and without SLI being enabled in the NVIDIA control panel.
Sure. Sorry about leaving possible helpful information.
I'm using CS6 latest update. 126.96.36.199
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:
|Texture Memory:||1024.00 MB|
|Device:||GeForce GTX 680/PCIe/SSE2|
|Total Memory:||1.95 GB|
|Shader Model:||4.0 or later|
|Devices:||2 (GeForce GTX 680, GeForce GTX 680)|
|Current Usable Memory:||1.79 GB (at application launch)|
|Maximum Usable Memory:||2.00 GB|
