After a fresh boot it works 100%. Then maybe on a 30 day system it can start to take a long time to initialize. It usually goes through all the intro screens without problem. There's a normal time this takes, on my computer. But now and again it takes more time, much more time. I haven't figured out what or where time is going, so to speak. Either some kind of memory allocation, a programming error in the game or something else behind the scenes. Changing cpufreq-set or letting it manage itself will impact performance when it's running like it should and I'm also getting CPU overheating messages in dmesg. But, these don't seem to be appearing at the same time in time. I'm using optirun and without it, running on Intel GPU, it starts right away. So the problem is it's not starting.
