I want to buy a gsync monitor, but it's really useful? If it is true that the gsync eliminate tearing, who tells me that reduces game ghosting? For example: the second bonus stage of Metamorphic Force on Mame... with monitor lcd (tn or ips) is unplayable... unable too see the scene... even without vsync.
What would change with gsync? I think, nothing.
Gsync is really helpful?
Re: Gsync is really helpful?
That wouldn't change with G-Sync no. ULMB, another feature found in all monitors with a G-Sync module however will make a significant difference at the cost of some brightness.

Re: Gsync is really helpful?
Is any game, regardless of how old it is, compatible with G-Sync? My Asus VG248QE doesn't currently have it, but I can buy a board that I can solder into the monitor that will give it that.

Re: Gsync is really helpful?
I don't really play beat 'em ups, but I did watch the demo for UN Defense Force: Earth Joker, which has fast background scrolling. I was able to make out quite a bit of detail in the scrolling backgrounds, although it's not perfect. And this is an IPS monitor rated at 4ms response time, at that. I agree ULMB should help the situation, if your eyes / head can take it (but it shouldn't be too much different from playing on a classic CRT, right?) although I thought the Metamorphic Force demos looked great with a stable image.
To answer your question, atheist: So long as the program running is outputting a resolution the monitor accepts, it should work. G-Sync does well on my machine with a wide variety of graphics APIs, including DirectDraw and OpenGL, but I think Vulkan would be fine too. I haven't gone crazy trying out unusual resolutions, but my monitor seems pretty decent in handling a number of resolutions.
In many situations FreeSync should be practically as good, and you get a bit more flexibility in input choice - FreeSync over HDMI is possible, in addition to DisplayPort. I think you'd just want to check that the display you choose has a FreeSync range close to what you'll be gaming at - so around 60Hz if you're doing a lot of arcade / console stuff, and 120Hz+ if you want to mess with black frame insertion or high framerate PC gaming.

Re: Gsync is really helpful?
For MAME, I'd think the variable refresh rate of G-Sync can help with some non-60 Hz oddballs (i.e. 54 Hz games like Raiden Fighters). I've been able to get some Namco stuff that runs at 60.6 Hz (Tank Force, Pac-Mania) to run decently with it. Ninja Ryukenden (57 Hz) also works well. In the nVidia control panel for MAME, I have it set to use Fast Vsync and G-Sync Monitor Technology.
IINM, sound stutter is a symptom of refresh rate mismatch.

Kinect? KIN NOT.
Re: Gsync is really helpful?
If you have G-Sync you don't need to fiddle with anything to get basic MAME running well, unless you run into some exotic situation or want to insert black frames.
Don't enable V-Sync for MAME or anything else, although that setting should make no difference as G-Sync overrides it - except in the case that the framerate goes outside the G-Sync window (which I think cannot happen if your monitor's G-Sync range covers its top refresh rate, as seems to be the norm; perhaps V-Sync does something if you bottom out below the minimum framerate).
I think MAME has sound decoupled, more or less, from video, and stuttering is due to having not enuf PC for the game and so the buffer runs out. Get moar PC (or more buffer, but that costs sound lag). If you are lucky you might be able to get the ASIO4ALL drivers + ASIO MAME working for far less latency in sound, but at the end of the day MAME still has to produce sound on time.

Re: Gsync is really helpful?
G-Sync is variable refresh rate. It only has a purpose for games that use weird refresh rates or games where your PC can't maintain a constant framerate.atheistgod1999 wrote:Is any game, regardless of how old it is, compatible with G-Sync?

It works for emulators and older PC games, but for emulators there's only specific uses (MAME games at odd refresh rates, DOS games, PAL games, Wonderswan) and for older PC games most of them are either locked at a refresh rate common monitors support or are pretty easy to achieve consistent framerates in.
Re: Gsync is really helpful?
I have a Gsync laptop and I will say that it is a godsend. I really only play old games via emulator on it and there is no screen tearing and virtually no input lag to speak of. The previous laptop I purchased (and returned) did not have gsync and everything looked and ran like complete shit in comparison.
