Dolphin loses performance in Ubuntu 16.04

[ggm]

Hi, anyone has this problem?
I upgraded from 14.04 to 16.04 in 2 ways, fresh install and with upgrade tool of Ubuntu, and in this 2 methods the dolphin loses performance, games who runs in 60fps in 14.04 drops to 30, 20 fps...

In 16.04 and 16.10 i tried different drivers of nvidia, 367, 360 and 375 and all of this drivers show the same problem with this version of ubuntu, but if i use them in 14.04 all works fine.


Anyonde know how upgrade without loses performance in Dolphin?

My config:

i5-2300
GTX 1070

It's an issue with something in Ubuntu I believe... I think the next release will fix it? Someone like degasus could probably remember better than me, but, Sandy + Ivy Bridge CPUs are hit by some kind of compiler bug.
