If you have a G-SYNC display, you'll want to make sure it's enabled here as well as in the 3D Settings. There are a few more ways you can customize G-SYNC under this tab. There are some games (usually older ones) that shouldn't be run at very high framerates, for example. This setting too can be used to curb power consumption. Max Frame Rate is similar to the first setting we looked at but it is in effect at all times if enabled. Still, every millisecond matters sometimes.
Nvidia recommends setting this to Ultra, but by their own testing, it doesn't seem to do very much in some of the most popular competitive games. Low Latency Mode is useful if you're playing a competitive game like Fortnite where you want lag and latency to be as minimal as possible. However, increasing the resolution is very graphically intensive, so take care.
This might sound like a useless setting, but it can be better than anti-aliasing at eliminating jaggy graphics. You could play a game at 4K and see it on your 1080p monitor, but you obviously wouldn't see a 4K image. Basically, it will render a game at a higher resolution and then downscale it to what resolution your monitor is. DSR - Factors (DSR standing for Dynamic Super Resolution) can be used instead of anti-aliasing to improve visual quality.
