Had issues with CUDA and After Effects CS6 11.0.1 Update but FIXED THEM
After updating to After Effects CS6 11.01 I started getting an error message about CUDA not working.Strangely CUDA was still working fine in Premiere Pro CS6, so it had to be the AE Update.And I am running the latest CUDA.The thing is it just wasn't showing up in After Effects and was using CPU instead of CPU for CUDA.I tried trashing After Effects preferences, but that didn't work, so I found and downloaded the standalone 11.01 update installer and that fixed the issue for now.
