Originally I had considered that update 1 fixed this mistake, but in fact, it is a bad implementation of mirrors in the module Spitfire.
If the Spitfire enabled the mirror, begins to egregiously overload the CPU in all cores. When I turn off the need to use my mod https://uloz.to/!euOGmmiHPpvU/spitfire-rearview-mirror-off-rar so the CPU is adequately busy.
