Ive just upgraded so cant say much other than never had any problems with performance, only the ridiculous 'lets not draw the enemy' optimisation trick. Got a video of me standing on the first floor of the crown with no one in sight, jump down and run 10 feet to spawn and hundreds of NC start popping up all around. Its pretty rubbish. If anyone knows how to improve this, would be great.
Nothing you can do until they improve the algorithm that picks what gets renders and what doesn't - you have 500 max objects around you that can be rendered, including vehicles. Right now it's just not great at sorting what is relevant to you and what isn't
