@b6hydra I'm still wrapping my head around this. When you renice all you games to -10, what is that actually doing? Giving them priority resource consumption?

@worldsendless Not resource use in general, just CPU time. The default for any process started by a regular user is typically 0. By renicing the process to -10 I’m telling the kernel that the game should get more CPU time than all other processes with a higher value. So all those Firefox tabs, slack, email, nonessential systemd daemons, etc. running in the background should now have lower priority. I say “should” because niceness isn’t the only factor the kernel uses when determining actual priority. I settled on -10 as a sane value because that gives the game more CPU time than nonessential processes but isn’t low enough to interfere with critical system processes.
