MAxwell GPUs will only be supported in the next CC2015 update.
Looks like I have to wait ... any dates in mind?
I'm just wondering if it would make sense to save already a secondary GPU of the same type before it's sold out ...
GPU not supported, still, why?
(GPU not available - incompatible device or display driver)
Vendor: NVIDIA Corporation
Device: GeForce GTX 980 Ti/PCIe/SSE2
Version: 2.1.2 NVIDIA 368.39
Total Memory: 5.84 GB
Supposed to be some kind of an update???
When will this be available????
Are you using the obsolete ray-traced renderer? If not, don't worry about it. That feature is only for accelerating the ray-traced renderer. I don't know of anybody who uses the ray-traced renderer. If, for some reason, you do want to use it, you should have a check box to use "unsupported" GPU's and it should work with that card. But you might not have the right version of AE. Double-check your version number. Is it 13.7.1?
But, again, you have much better ways to do 3d in AE, so don't worry about the ray-traced renderer.
