The only thing you need to do to fix the crashing is change the resolution to the OG format. From your desktop change the resolution to 1280x720

And you need to force the game to start up in minimized mode. You must keep it in minimize mode to fix the screen tear.

Press win+r, run %appdata%
This address: AppData\Local\LucasArts\Star Wars The Force Unleashed 2
Open Config file in notepad
Find this line: < near the bottom it will say minimize mode or something similar(cant remember)
Change it to: < change NO to YES

Never had an issue with it >
