When I raised this back in August, I could not resolve the performance either with Ubuntu drivers or Intel. It just seemed upping the kernel from 4.6 upwards stopped the performance. You don't have to upgrade to 16.10 to see the issue. Any way tried to upgrade 4 weeks ago incase the issue had resolved it's self with kernel 4.9 and nope it's still there.

Currently back on kernel 4.6 everything is good again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1632165 Title: modesetting driver unbearably slow on intel graphics To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1632165/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
