How has this not been fixed?
When going into the upgrades panel to upgrade or change the appearance of your car, the game starts a memory leak that either immediately or after a few minutes crashes your game. Memory usage goes from 80% before going into the upgrades panel to 98-99% afterwards for me.
If your game somehow miraculously doesn’t crash while you are at 99% RAM usage, it stutters like crazy in a race and is unplayable.
I know I’m not the only one with this issue because I see people talking about it everywhere but it’s not being addressed by T10 whatsoever. This literally makes the game unplayable and removes a core component of Forza: modifying vehicles.
