Is Pascal still not supported? Are there anyways around this/fix it? Any help is much appreciated
From the developer meeting notes (Sunday 31 July 2016):
Everyone wants the GTX 1080 cards supported with Cycles, unfortunately the required CUDA 8.0 is still not official released. We can add their release candidate though. Sergey Sharybin and Brecht van Lommel check into this."
Proably applies to GTX 1070 too...
