    AMD Demonstrates "FreeSync", Free G-Sync Alternative at CES 2014

    Tell me how am I confused.

    AMD Demonstrates "FreeSync", Free G-Sync Alternative at CES 2014

    Don't know enough about CUDA to say for sure, but if there exist a VESA standard for NVIDIA to implement GSync equivalent functionality for the past decade, yet none of NVIDIA, AMD, Intel, and any of the monitor companies came up to use this standard to solve a problem John Carmack has been...

    AMD Demonstrates "FreeSync", Free G-Sync Alternative at CES 2014

    Well I did post the same thing on Overclock.net... I admit I have a Geforce card, but I am more interested in figuring out how NVIDIA can be so stupid as to miss an existing standard. To my best knowledge they didn't. They just chose the more expensive but better way. Didn't really read eDP...

    Here: See, you need to know the frame rate of the content, and you cannot know that for a game.

    If you check figure 4 of the patent, you can see that the patent requires determining the frame rate of the content before the frame rate of the display can be updated, which cannot be known for games. The patent talks about video more, which makes sense because the framerate of video are fixed...

    AMD Demonstrates "FreeSync", Free G-Sync Alternative at CES 2014

    By the way, I studied CS in college and am working for a tech company, just to show you I am not a total idiot so we can discuss instead of get into a heated argument :) My point is this: without some software running on the monitor to wait for a draw command from GPU, there is no way the...

    AMD Demonstrates "FreeSync", Free G-Sync Alternative at CES 2014

    Just reading the abstract. This is different from my description only by who predicts the frame rate. I said software, and this patent is essentially saying hardware. You still need to know the frame rate ahead of time, which you can do with video but can't do with games. You still have some...

    I am speculating too, based on my technical background. Tell me how it works.

    Copying my post on overclock.net: FreeSync uses variable VBI, meaning the driver needs to setup the proper VBI for the next frame, therefore requires the driver to predict the future. If the app isn't running in constant FPS, then FreeSync will fail when FPS changes, and you will still see...
