I followed the Wiki's Gaming page and installed linux-zen (from testing, together with the corresponding header package) in order to get the bfq scheduler and more fps in games. But it is much slower. I use Unigine 4.0 to benchmark gpu performance. Here's the result:

kernel - min/avg/max fps - score
linux (4.9) - 8.3 / 47.4 / 92.2 / 1194
linux-zen (4.10) - 5.4 / 11.8 / 24.1 - 297

The gpu is a RX 480 using the amdgpu driver.
This task depends upon
