Enhanced Sync + FreeSync < V-Sync + G-Sync
Think about it: the signal is literally being processed by two GPUs (the graphics card and the GPU known as the G-Sync Module in the monitor itself). There's really no circumstance where G-Sync should be faster than FreeSync unless the graphics card driving it is faster. That's no fault of the technology though.
Well it's marketing I have read
Scam it was then.
Those tests make people think. I never had trust in this G-sync tech by the way.
(real) Competitive people will not play in 4k@60fps@60Hz with G-sync & Vsync ON for sure so the little input lag will never be noticeable with a recent monitor, in games where a graphic card might struggle to keep the fps high. I say this cause input lag can be an issue in competitive games only. I don't know anybody who can notice it even on a TV screen as it is about ghosting but cyborgs might exist
No way can somebody play a competitive game with ultra graphics if it kills the min/max fps but lies have been told about G-Sync module for sure.
By the way I have read it's better to let nVidia Vsync to default in the nVidia control panel BUT put it OFF in games so G-Sync will do the job as intended.
If i know that freesync monitors do the same job as g-sync now Nvidia has to give me a reason why I should pay that extra G-Sync module in the future ?
It appears there is a sort of certification, they said the screens pass like 300 tests for quality, so you would pay like $200 extra to be sure the "thing" works.
Now they tested the Freesync panels, I see no reason if you can see the monitor you want pass the nVidia tests (maybe not 300 I don't know about this I didn't read much about those). They report the Acer XG270HU as a 2560x1080 panel...it's 2560x1440 so you can see a lack of professionalism.
I do understand why they did lock G-Sync on monitors without the module : 1. Money / 2. Less bugs to fix
Now let's remember ATI hmm AMD said you could use different cards to pair in your computer for calculation (it could be games or anything) like a 980Ti + a RX 560X for example. Like a SLI without any synchronization. It's all about drivers. Imagine you could pair your 2080Ti with a 1080Ti, I don't see why you could not. Drivers just let you use 1 of the cards for PhysX but think about it, it's a driver lock.
