Thank you all for sharing your reports about this problem, we believe this is related with driver settings and frame rate limiters.
- Disable the overrides in the driver settings,
- Make sure to press “APPLY”
- Restart the game client.
Also you can cap your FPS.
This will help prevent issues with the GPU’s utilization.
Go to Settings > Visuals > Max fps > Set this to 60, this should help to bring the utilization back down.
Additionally, please be sure to check in your NVIDIA Control Panel under Manage 3D Settings > Program Settings > Select New World, and check that Max Frame Rate either shows 'Use Global Settings (Off) or just Off.
Please let us know if you need more assistance and thank you all for your contributions to the Beta.
