Thanks for your reply,
I don't have a slow config that's why I don't understand I have an I7 4790K with 16go RAM &1080ti, or maybe it's to short (CPU maybe) I don't know but didn't have this issue before it's like the normal game around 1300 or more when game is already advanced
Ok for the 4.06 it makes perfect sense then, I thought it was fully backward compatible
Just a shot in the dark here but do you have an SSD? I seem to remember the engine not liking ssds for some reason
