Hi Konrad, Nvidia GTX 1060 is sm_61 and per https://github.com/fspiga/QE-GPU, it supports up to sm_60, based on my experience QE-GPU will compile with sm_61 however when you run pw-gpu.x it will throw errors, hence there should be a slight modification on the QE-GPU source code to include sm_61, it should be easy to do that. I am using Nvidia GTX 1070 and have been working on it with QE-GPU for 2 months now. The only catch, which Mr Spiga always points out, is that the DP performance on GTX cards is very slow , which is like 1/32 (or 1/24) of the Single Precision
