Severe slow-motion gameplay and menu lag

Since installing UFC 6, the game is extremely laggy. Menus are sluggish and all fights run in what appears to be slow motion. Audio plays normally, but fighter animations, movement, and strikes are significantly slowed down.

Troubleshooting already attempted:

• Reinstalled the game completely
• Restarted Xbox Series X
• Changed display from 120Hz to 60Hz
• Disabled VRR and additional video features
• Confirmed game is installed on internal SSD
• Verified game is fully updated
• Other games run normally with no performance issues

The issue occurs immediately after launching the game and happens 100% of the time, including offline fights. Audio remains normal while gameplay appears to run at a much lower frame rate or speed.
