... Are there any draw backs to using Rivatuner fps limiter?

Yeah just stumbled upon this with MSI afterburner.. Can any one explain to me what are the drawbacks to using this over say adaptive v sync or g sync? Am I missing something? Because this just seems like a work around making something like G sync completely unnecessary because this will cap the fps while at the same time stopping screen tearing with no input lag..

@sSubZerOo: It will not get rid of tearing and judder. It just limits the frame-rate. Try it and you will see.

I thought tearing specifically has to do with when frames exceed your refresh rate? I currently use a 144hz monitor.

The only way to eliminate tearing is to sync your refresh rate to the frame-rate. That being said, if you are running high fps on a 144hz monitor, tearing is a lot less noticeable.

You get tearing below and above your monitor's refresh rate. Even if you cap your fps to your monitor's refresh rate, you still get tearing. You have to be perfectly sych'd which requires vsync/gsync.

See the confusion I have with this is specifically Nvidia's Adaptive V sync in which it specifically says it enables v sync when frames reach the refresh rate.. And disables it when it is below the refresh rate.

That's because it's better to get some tearing rather than drop down to 30 fps.
