It sounds like you have either a virus or malware running.

Lsass.exe should be using very little if any resources at all after you login in at start up...and it shouldn't react to a game at all as far as I can determine.

I'd recommend disabling your internet connection, shutting down the PC, and unplugging the power for 90 seconds to wipe the system memory clean...then plug it in and reboot without reconnecting to the internet. Run a full system scan while offline with Windows Security "virus and threat protection" using "scan options" to select full system scan.

If Windows Security doesn't find anything I would hit a second online scan tool like Trendmicro and run their free scan tool...make sure to temporarily disable the Windows Security virus scan tool to prevent conflicts. https://www.trendmicro.com/en_us/forHome/products/housecall.html

You still need to follow the shut down instructions regardless of scan tool...malware can remain resident in system memory even after rebooting...it's necessary to completely power down and unplug the machine to clear system memory.
