    Lightroom cc Always Crashing with GPU Acceleration on




      My version of lightroom crashes constantly in the develop module whenever I try to run it with GPU Acceleration turned on.


      My system presently has two GPU's (Both the same video card in it - 2 x Gigabyte Nvidia GTX 980 Ti)

      Each video card contains 6 GB of VRAM. There are no other graphic adapters built into my motherboard.


      I will attach Lightroom the information displayed when clicking on "system information". The only thing obviously wrong with Lightroom's hardware analysis below is that lightroom thinks I have one graphic adapter with 12 GB of vRam, and a second graphic adapter with 0 GB of VRAM. If this misdetection is the cause of the issue, I would hope that it is fixed in a future patch.


      Thank you.
