Choose the screen or action that is failing before changing PC settings.

Use the dedicated launch-button, loadout and stats guides for status checks and reporting. TPM and Secure Boot have a separate requirements guide. None of these pages promises an individual fix.

If the game will not start

Try one change at a time and test the game afterward, so you can see whether it helped.
