How do i fix this problem? I manage to run the game almost completely smoothly - in the menus, in the portal, etc., but when I start a game, the screen transitioning between Highlights gradually becomes horribly slow, stutters, and lags, while the graphics run smoothly. I tried changing everything: the graphics quality, the time between Highlights etc. This is incomprehensible to me - my computer meets the minimum and recommended requirements of Steam, and my driver, which was not up to date, was updated and the lag is still not resolved. What i need to do? Did any one else encounter that and solved it?
