Same things happening to me. Im getting like 1fps in campaign and game crashes playing that heroes mode. I downloaded the trail off of origin 2 days ago. The single player tutorial/ challenge mode runs perfectly but anything else is unplayable. I lowered all the settings and it makes zero difference. I have an i7 7700, geforce gtx 1070, and 8gb ram. I also have a toshiba dt01aca100 hard drive( i know its terrible) which used to run at 100% disk usage playing mankind divided on ultra but after moving things off of it and keeping it below 30% capacity its been working fine. But its been acting up pretty terribly when it comes to battlefront 2
