How is G-SYNC different from standard V-Sync?
Gsync adaptively syncs to the exact number of frames your gfx card dips-to..
IMHO.. yes it's better than Vsync.. but now there's the trouble of intermittent time-dilation/contraction, because it may be holding onto a frame longer or shorter than it's relevant..
In practice.. you can't tell, because humans arn't very good detectors.. so the overall smoothness trumps the fact that you're not getting (closer to real frames)..
IMHO, it's irrelevant atm, because ULMB is far more desirable..
ULMB gives you MOTION CLARITY, and that's immensely more pleasing and noticeable to the eye..
But.. ULMB only works well @ 100hz +,,,,,,, on the asus swift, ulmb goes up to 120hz instead of 144, a shame, but still already very good..
Now, because ULMB requires insane Frame rates, it usually can't be coupled with Gsync.. due to average GPU power..
There's high risk in building a monitor with features that only works for people with SLI 970s..
Therefore , because ULMB is far more attractive than Gsync, and it can not be used together... Gsync is currently God damn useless.
ULMB is the most important feature because the HEART of our modern visual experience is NOT only Resolution, but Resolution IN MOTION.....
ULMB is the only known way to regain what we lost from the CRT era..
OLED is NOT the ****ing answer, because it uses sample and hold.. not only that, but because OLED is NOT very bright AT ALL.. it REQUIRES sample and hold just to produce a bright enough picture, which means,, EVEN if the pixels can come down in latency and respond, IT CAN NOT possibly produce a bright enough image in that small time frame..
WHEREAS a backlit system absolutely CAN..
