I had terrible system freezes in almost every game, until I made some steps that helped me. I feel I have to share this solution in case someone has similar issues. This will only work if your freezes are caused by CoherentUI, but you can try anyway. Idea is to limit cpu usage of CoherentUI processes. For this purpose I use cpulimit tool from Ubuntu repositories, but if you have any other similar tool feel free to use it. 1) Install cpulimit ("sudo apt-get install cpulimit" for ubuntu) 2) Start the PA 3) Open system monitor 4) For every CoherentUI process there write "cpulimit -p <process id here> -l <max cpu usage, for example 20>" 5) Play I played few games today and my system kept working without freezes, even though PA crashed once. If that helped anybody please write back.
For people who using open source video drivers I also recommend to use "cpufreq-set -g performance". It's usually give a big boost for Mesa.
