So… is a monitor with G-Sync worth the extra cost?
[/quote]Ok, so I did some research on this, and I found out what G-Sync does.
Let’s say you have a monitor that runs at 60Hz.
If your computer renders less than 60fps, you might get tearing if frames are not swapped into the frame buffer in sync with the refresh of the monitor.If you render MORE than 60fps, not only are you going to get tearing, but you are spending cycles rendering frames that never appear on the screen.
If you enable vertical sync you will render exactly 60fps and they will be rendered to the screen at exactly the right time to display all of them.
However, if you are rendering less than 60fps enabling vertical sync can cause problems. Yes, you will avoid tearing because frames will be drawn when ready, but you will also get input lag because the frame will appear later than it should. This matters if you are playing a fast fps or fighting game. You know how the Smash Bros players always need to use a CRT because the LCD lag is a problem. That kind of lag.
What does G-Sync do? First of all, lots of G-Sync monitors seem to mostly have 144hz refresh rates. That’s crazy good if you can render that many frames. Just running at that speed even without gsync is like wow. That can definitely make a difference in real-time gaming. Pretty sure they make 144hz monitors without GSync, so that is an option if it’s cheaper.
What G-Sync does is take care of you if you are rendering less than the refresh rate of the monitor. It still eliminates tearing by rendering the frames to screen in sync with the monitor refresh. It also eliminates any input lag. You basically get the benefits of perfect vsync whether you are rendering max frames or not.
Also keep in mind, that’s what it does on paper. I have no idea how well it works in practice. You’ll have to judge for yourself. Also, you’ll have to judge the price for yourself.
Personally, if you can render enough frames for vsync, and you’re not playing a super serious fighting game or fps, I can’t imagine it being necessary.
