Blur Busters Forums

jorimt, RealNC, appreciate both of your efforts to explain this. I read through the explanations in the guides, but there were still gaps in my understanding, in how I parsed some of the ideas, and I couldn't get to a clear model.

Sometime it just takes some hand holding and translating concepts ...

Re: RealNC
Are you saying that for GSYNC+VSYNC off there should be a minimal amount of tearing if FPS is capped below max refresh rate? When I was playing around with it, I saw the same sort of tearing (objects looking weird) as I panned the screen. Is this caused by the intermittent variance ...

What causes tearing then? Is it that the GPU is dumping a new frame into the frame buffer before the scanout is finished?

Then GSYNC+VSYNC off shouldn't do much to fix this since nothing is preventing new frames from being dumped in.

VSYNC alone tries to fix this by having an extra buffer, and ...

To clarify, the idea of the refresh cycle/refresh rate is really an abstraction? The actual process is just reading from the buffer to scanout + VBI. And this entire unit is taken to be the "refresh cycle"?

If so, I think that helps a lot because although I saw the diagram, I was still struggling ...

I went through the GSYNC 101 pages and still wasn't quite sure how all the pieces fit together. Was also having some trouble finding a detailed source elsewhere that really put all the pieces together (which was a bit odd given the ubiquity of the technologies).

1. How does refresh rate work? Why ...

For better interpolation, you will be looking at several thousand dollars for a TV that contains a recent "artificial-intelligence" interpolation chips.


Thanks for the details about FRAT. Very fascinating.

I tried googling for recent AI chips, but what I found didn't seem to explicitly call ...

I've been playing Animal Crossing (30 FPS) on my Vizio P65-C1 (120Hz) TV, and after firmware updates, it's looked very blurry when running/panning sideways so I started playing around with the interpolation options on the TV. After turning up Reduce Judder, it's cleared up the image when moving, but ...
