All the 1.10.x versions are terrible if you are using an Intel hd-xxx, with opencl enabled. Disable opencl or roll back to 1.9.x.

All the previous versions are available on the website.if you are using a store version, I don't know.

Small reminder that my problem - as OP of this topic - is NOT present on 1.9, both with opencl enabled. So it's a regression from 1.9 to 1.10 for me. So the same system, same driver, works fine with 1.9 to is unusable slow with 1.10.
