According to various sources, it is a frequent laptop problem. I am unable to go fullscreen in Destiny 2, only Windowed Fullscreen, which severely undermines my performance. Upon choosing Fullscreen (likewise, Alt+Enter), after ~15 seconds of glimmering the game goes to Windowed mode. What I have tried doing: - Checking and restoring files; - Reinstalling the game; - Clean drivers' reinstallation (both for NVidia and Intel GPU); - Meddling with files in "C:\Users\1\AppData\Roaming\Bungie\DestinyPC\prefs", setting "window_mode" value to 3, and file to read only, respectively, as some forums suggested Everything to no effect whatsoever. Any ideas as of what might be causing this and/or how I can fix it? Thank you very much in advance!
