Hey there. Thanks for reaching out. Here's a few suggestions that may help with this.
- If your monitor is using a high refresh rate (144 Hz, 240 Hz, etc.), try lowering this to 60 Hz and then launch BF6. Then, once loaded back to the menu, switch back to the previous refresh rate.
- Try using borderless windowed mode. Not full screen.
- Disable DirectX 12 or revert back to DirectX 11.
- Do a clean install of your GPU drivers. Try the latest version if you've got an older one.
- Disable any overlays. Steam, EA App, etc.
- Repair/verify your game files.
Let me know how it goes. Thanks!
