1. go to Steam
2. search for Star Wars Jedi Academy
If the problem still persists after that we'll try to help you with specs and settings.
i've deleted my JA on computer and than purchased the steam version but the problem remains but why?, anyway i have bought the app store version and it's OK for now.
By the way thanks a lot for your reply
