I am currently looking at the AOC G2460PG monitor, but I don't know if it's good. The reason I want to go with g-sync is because I can't keep constant 144 fps in battlefield 1.
It should be noted that the real benefits of variable refresh rate technologies [G-Sync / Freesync] really come into play when viewing lower frame rate content, around 40 - 75fps...
It should be noted that the real benefits of variable refresh rate technologies [G-Sync / Freesync] really come into play when viewing lower frame rate content, around 40 - 75fps typically delivers the best results compared with Vsync on/off. At consistently higher frame rates as you get nearer to 144 fps the benefits of FreeSync (and G-sync) are not as great, but still apparent. There will be a gradual transition period for each user where the benefits of using FreeSync decrease, and it may instead be better to use a Blur Reduction feature if it is provided. On FreeSync screens this is not an integrated feature however, so would need to be provided separately by the display manufacturer.
