Re: Battlefront 2 stuck at optimizing shaders...
> try this...it fixed my issue If you're unable to launch the game there's another way to swap to DX11. Go to C:\users\your windows account name\Documents, then go to STAR WARS Battlefront II\settings. Choose to open BootOptions with notepad, and you'll see "GstRender.EnableDx12 1" at the start of the document. Change that one to a zero to get "GstRender.EnableDx12 0", save and start the game.
disabling dx12 is the only way to fix this issue for now.
After doing this the game should start up normally without issues. Just one thing...go to graphics settings in game and disable dx12. Otherwise it will re-enable after you close the game
