Could it be that the issue is audio related? I definitely have no old folder in my installation though, it's new and clean. Added some callout packs today though.
I'm not sure how to do that. Do I need to put them into the RHP console and then how do I reload what scripts?
EDIT: I just tested with an fps counter. When I start the game with LSPD at the airport I get 45-53 fps. When I call for some backup it drops down below 40. When I call for a lot of backup it drops below 30 as worse as 24 fps sometimes. I don't know if thats normal. Could be that my whole system has performance issues 😞
