what happens when FPS goes over refresh rate and should I cap it?

[AnalogCanavity]

So let's say I have a 60hz monitor and I'm getting 80FPS, should I cap the FPS, because it's making my GPU work harder, and the monitor can't even output it? or does it help in some other way.

 

Thanks

It's fine to leave it.

If its way above it then screen tearing will start to become a thing but you should worry about it. id take screen tearing over input lag

Ok, so I have this problem, but only in minecraft strangely enough (I have less demanding games) where I get 500 FPS with a 60hz screen with a ton of screen tearing.

Your GPU is built to work hard so as long as it isn't overheating or something there isn't really a problem

there's a really simple solution: Turn on V-Sync

Yeah, I figured that out while messing with settings, but what's even worse is getting less than your refresh rate in FPS, not only screen tearing, but it's so... terribly... slow...

To back up, let's say you're getting 120 FPS on a 60Hz screen. You can actually see both frames, you'll just see the top half of one and the bottom half of the other. In other words, you still get tearing. If you want to cap the frame rate, using Vsync is an option, but keep in mind if the performance drops below the refresh rate, it'll drop the frame rate to bottom half. So if you're getting 59 FPS on a 60Hz display, the frame rate will drop to 30 FPS until the GPU can get back to 60 FPS. If you have an NVIDIA GPU, you can enable Fast Sync which will render only the most recently rendered frame if the frame rate exceeds the refresh rate.

 

A good article about all of this can be found at https://www.anandtech.com/show/2794 (note that "Fast Sync" is triple buffering. Any triple buffering NVIDIA had previously only worked on OGL applications and may have been wonky)

I usually use this one
