Fix #5: Launch Options & Big Picture Mode Trick Sometimes the issue is that DW9 launches in a background process that doesn’t read controller focus. You can force focus via Steam launch options.

Few things are more frustrating than booting up Dynasty Warriors 9 (DW9) on your PC, ready to mow down thousands of soldiers with cinematic flair, only to discover that your controller doesn’t work. You press a button. Nothing. You move the stick. The camera spins wildly. Or worse—the game insists on showing you keyboard prompts while your Xbox or PlayStation controller sits there like a brick.

Since its controversial launch in 2018 (and through subsequent updates leading into 2026), Dynasty Warriors 9 has suffered from notoriously poor PC peripheral support. Unlike its predecessors (DW8: XL) or its successor (DW10: Origins), DW9 uses a unique controller API that conflicts with Steam Input, Windows drivers, and Bluetooth stacks.
