Hi,
R. Cord here, Independent Expert. Hope you are doing well.
Yes, this behavior is expected because your monitor's refresh rate is 165 Hz, so even if your graphics card is capable of producing more than 165 frames per second (fps), your monitor won't be able to display them.
When you enable VRR (Variable Refresh Rate), your monitor's refresh rate adapts to match the output of your graphics card, so it can display as many frames as your graphics card can produce. But when you disable VRR, your monitor's refresh rate is fixed at 165 Hz, which means it can only display up to 165 frames per second.
So, in your case, if you disable VRR and your graphics card is capable of producing more than 165 fps, the extra frames will not be displayed on your monitor.
Is there anything else I can help you with?
Please let me know if you need any further assistance.
With my best regards,
R. Cord
