If you are having issues with fps drops, make sure you're using our native launcher and update your graphics card drivers to the latest version.
Additionally if you have dual GPU system (integrated and dedicated GPU setup) where the dedicated GPU is by NVIDIA, follow the directions below:
Open the NVIDIA control panel
Navigate to 3D settings > Manage 3D settings.
Open the Program settings tab and select the program to customize.
Select Preferred graphics processor for this program from the second dropdown menu. Your NVIDIA GPU should appear as "High-performance NVIDIA processor".
Save your changes.
Restart the client.
Please note: If the 'preferred graphics processor' option is not available, you do not have a dual GPU system.
