Preferred Refresh Rate - switching between hertz

[tomsanity]

I recently purchased an Asus vq248qe and found out that when running 144hz on the desktop the GPU has to overcompensate, and as a result works harder. I found a setting in nvidia inspector called 'preferred refresh rate' and was wondering if how I think it works is actually how it works.

I set my monitor refresh rate to 120hz, which fixes my issue, but I play a lot of CS:GO and so would like the convince of the refresh rate switching to 144hz when I launch the game. Does changing 'preferred refresh rate' to 'Highest available' for CSGO as a specific program cause my monitor refresh rate to switch to 144hz when I launch the game? Or does 'highest' mean the highest desktop refresh rate?

Thank you in advance.

Don't confuse refresh rate of the monitor with the frame rate output of your GPU.

If you set the monitor's refresh to 120Hz, that's the highest it will be and remains constant.

Your frame rate will vary.

Thats odd, I havent noticed my GPU working hard weather I have my monitor at 60hz or 120hz.

Are you setting the max refresh rate on the monitor itself or through the OS? If you set the refresh rate on the monitor to 144Hz, that should be the max that the 'Highest available' 'preferred refresh rate' setting will set it to .

It only happens at 144hz for me, 120hz allows the GPU to idle correctly.

I haven't change anything on the monitor itself. I've only changed the refresh rate on the OS. So going by what you're saying... as long as my monitor is set to 144hz, even if I set the OS the refresh rate to be 120hz, the 'preferred refresh rate' set to 'highest available' will cause my application to run at 144hz?

That's definitely how I'd expect it to operate.
