Hello,
I finally found how to reach 60 FPS on my Raspberry Pi 3 Model B (RPi3B) with Slackware ARM 14.2 (SARM14.2)!
Here are the instructions:
https://github.com/anholt/mesa/issues/73
Remark: You do not need the downstream/anholt Mesa version, indeed I tried with the official/original/mainline Mesa 17.0.4 and I also reached 60 FPS.
Of course, if you first want to know how to install SARM14.2 on your RPi3B, here are the instructions:

Have fun and let's play video games on the RPi3B with SARM14.2
