Per ol' Roy, nothing. All the fluff is in response to "Nvidia Pressure".

Seriously?

No, I do not agree with your claim. Or your cynicism. He was asked if it was a frame buffer. He said no, it's not. Third-party testing of input latency proves that it cannot be a frame buffer, since the latency does not allow for a full frame of delay that would correspond to a frame buffer.

If you really are going to take a nihilist approach to anything that ever comes out of a company, keep your opinion to yourself.

More like refreshing as often as possible to minimise flicker and to reduce the amount of time the next frame buffer flip has to wait if it misses the scan-out window.

How many times does it need to be said?

There is no frame buffer.

Also, that entire description is completely wrong. That's not how it works, at all.

Yes seriously. Now I'm no expert, but I'm sure a buffer render is pretty instantaneous, no? Not a full frame's worth of delay, however long that is. Sorry, but I just don't readily accept whatever is said so you have to excuse my cynicism

So when Tom Petersen say they're rendering into A and B and scanning out from these, what is this A and B if not buffers?

Look up how traditional no-v-sync rendering is done. I was confused about this as well but that description is for how any GPU rendering works, unless doubled buffered.

Can you accept that?

...No? Because it could still be inherent to FreeSync. Not even just the A-Sync specification, necessarily, which it could be, but also AMD's hardware and software implementation of that specification that they call FreeSync.
We've been through this already. You just can't accept that there are things the protocol has absolutely nothing to do with.

I'm not struggling with anything except trying to convince you of reality.
I know you're trying to convince yourself that I'm only doing this because I'm a fanboy or something (which would be weird given the 5960X/GTX 980 system I own, as well as the 4900MQ/GTX 780M laptop). It looks to me like you're either an Nvidia fanboy, or someone who doesn't like being forced to admit he's wrong.

And how do you know they have nothing to do with these things? Are you an expert in the protocol? Do you know which parts of A-Sync are included in the FreeSync drivers, how they interact with the monitor firmware and hardware? Why are you so certain that there is no possible way that FreeSync could be causing a problem?

There are buffers in the GPU, because that's how GPUs work. This:

The important point is that there is not another buffer in the G-Sync module. At least, not one that is between the GPU and the pixels, that each frame is forced to go into and sit in. There is RAM on the G-Sync module, and some of it is used to store frames, but it's a look-aside buffer, not directly in the display path. And so doesn't contribute to latency.
