I've noticed this a few times now. I have nothing running in the VM except PT4 which is doing a 'get hands while playing' thing. Have just finished a tourney or ring session and have time to contemplate some navel fluff when I notice a lot of disc activity and things have slowed down in PT4, real slow with task manager shows CPU topping out (PokerTracker4.exe, not HUD). The last time I noticed this, PT4 maxed the CPU for about 20 minutes but when I stopped hands auto import CPU usage dropped to squadoosh.
So this time I got ready to grab a screenshot and logs files. Same deal, CPU maxing out when nothing is running except auto hand import but there are no hands to import. See image.
Is there an explanation or should I raise a ticket?
