I think this is one of the first necessary patch for those who install mods in the game.
In addition to Stream memory fix 1.0, the archive contains 2 test versions of fix version 2.2, which also increases Vehicle Streaming - the maximum amount of memory that is allocated for the models of cars that are currently displayed, i.e. if you put HQ models, then in the original game there will be fewer cars.
Version 2.2 will be useful for owners of a 1c license (because StreamMeMfix 1.0 did not work for me on it).
