FPS drops when moving cursor

[Yarxideyn]

Greetings Adventurer!

We would like to assist with the FPS issues you are experiencing. Please try the following to see if these help:
- Try switching to DirectX 9 by selecting the ‘Config’ button on the launcher.
- Update and reinstall the drivers for your graphics card. (We understand you have done this, however, we would ask of you to try once more.)
- Perform a clean boot by opening the task manager and select the 'Start up' Tab. Disable everything.
- Please be sure that Final Fantasy XIV is installed to the C: Drive. It seems you currently have it installed on the O: Drive.
- Please be sure to disable or remove any overlays (Discord, Steam, NVIDIA etc.) as they may interfere with startup.
- Make sure that the Windows OS is fully updated.
- Reinstall game.

If you do not see an improvement, please feel free to respond to this thread for further troubleshooting.

Thank you for visiting the FINAL FANTASY XIV Technical Support Forums!

Alright, so disabling the discord overlay has helped the problem. The FPS drops are not as severe but are still present.

Edit: So upon further testing, I can't really tell if it has actually helped the problem. Might be within the margin of error. The core issue still persists, however

Alright, so I managed to resolve the issue by reducing my mouse's polling rate from 1000 to 125 Hz. Now the game is unaffected FPS-wise by mouse movement.
