Yes please

It's no secret I've never really liked TFT's for games, but things are slowly getting better

[kalniel]

Agreed - it's really time we stopped emulating CRTs. This doesn't prevent that, but helps mitigate it somewhat hopefully.

This sounds like triple-buffering, but done expensively in hardware? Please tell me I'm missing something

The price of the module is meant to be around £120 to £130(if you include VAT),and IIRC the price is meant to drop closer to around £100.

However,it will only work with 144HZ(not sure about 120HZ) monitors it seems.

ATM,this rules it out for me(despite having a compatible card),as most IPS panels are not 144HZ.

Nope. Triple buffering runs at 60 etc. hz still. This is saying only refresh screen when frame buffer from the graphics card is full. But unfortunately still a minimum of 30hz because TFTs are still set up to emulate CRTs (though they're just repeating last frame if that's the case).

Saying triple buffering runs at 60Hz is technically accurate but rather misleading.

The graphics card can't run faster than flat out. The display can't go faster than the native speed it updates its pixels at (because it may not be a CRT, but it does still have a matrix of pixels to drive simply because you can't wire up each pixel individually).

On displayport (which really has nothing in the slightest to do with CRTs, closer to Ethernet if anything) you have the option of sending a lot more frames per second than a display can manage. If, on V-sync, the display picks the latest complete image to display, then you get better than Vsync rendering speeds and no tearing. That is triple buffering, but moving the front buffer out to the display. That actually makes some stuff harder, if the screen update speed over DisplayPort is faster than the LCD matrix update speed then you probably want to start displaying the current in-flight frame as you will have it all in buffer before you need that date. That kind of nonsense comes out in the wash if you do it in the display engine.

Anandtech has quite a glowing praise for G-Sync,

which is odd given one of Anand's pages gives the best description I have seen for triple buffering.

Thing is, there must be something clever behind this to get the likes of John Carmac on stage. Unless his rocketry experiments have cleaned his bank account out

It could be he just has close ties with Nvidia,especially with their OpenGL support.

My concern is that it'll carry a high price premium for monitors that come with G-sync vs those without.

I may be wrong here but my understanding is:

Having g-sync means that your monitor doesn't have a native refresh rate. The refresh rate will be dynamic, refreshing the screen only when and immediately after the graphics card generates a new frame. Assuming the frame time isn't too fast to be displayed (>144Hz) or too slow when it'll repeat the previous frame (the pixels need refreshed or they'll start losing contrast).

This is different to all types of buffering where the screen will refresh at its native speed eg 60fps. The buffers are just there to decide which frame is most appropriate to be displayed at the time that the refresh is due.

Will we see g-sync 1440p monitors? If so would that make them comparable with 120hz+ monitors which seem to be the craze right now?

I expect so.

No. Gsync is quite different to simply a high refresh rate.

Ah, trying to get my head around it (g-s) and especially why the refresh rate seems to be king over resolution. Unfortunately I have nowhere around me I can see either, so first i will experience both is if/when I buy one.

Off topic but: What would you go for? Res or refresh? It's for gaming but fps, especially online pm like bf3/4 really isn't a priority so making me a better gamer isn't the goal here, just finding a great looking monitor to make use of my new 780.

Resolution in your case then.
