The u-turn issue is a coding thing and I would love to see it fixed, but I am unsure if they can fix that. Your frames are dependent on the RIG you have, the plugins you have installed, how modern your plugins are, how many texture mods you have, how many custom cars you have and of course how many scripts you have. I get over 60fps EASY after I reinstalled LSPDFR and Rage and also purged out old plugins. Before I had old plugins, retired scripts and I would get 35fps at most, have terrible texture pops, and the civ cars would bug out because I had so many customs. I also use a standalone DLC folder where I keep all my cars that I have in my game.
