Back to the patches . . .
So has this made it into a GIT REPO, or is it just a bunch of patches prior to any specific pull request?
If it has, where? I'd like to feed it to my 380X (Tonga/Antigua) and see what happens.

Of course this theory doesn't quite fit in practice, because the fastest refreshing displays are about 144 Hz. Also, high rate refreshing has the disadvantage that you need more bandwidth for the video memory and display cable - and as a consequence more electric power However, I can understand that some people prefer a display with high refresh rate which works with all gpu vendors and is additionally a bit cheaper than adaptive sync monitors. They at least have a kind of similar effect.

The major problem with low FPS are sudden large drops of FPS. I.e. if the game cannot manage a steady 60 FPS with 60 Hz refresh rate, the FPS will instantly drop to 1/2, 1/3 etc. of the refresh rate. i.e. 60/2 = 30, 60/3 = 20 etc. If the monitor's refresh rates are quite high to start with, it definitely looks quite a bit better in this regard. A game that not quite manages 60 FPS on a 120 Hz refresh rate will drop down to 120/3 = 40 FPS, then to 120/4 = 30, 120/5 = 24 and so on. With nowadays typical 144 Hz the differences between swap intervals get even smaller. This is what schmidtbag was trying to explain.Last edited by brent; 11 February 2016, 05:51 PM.

Higher refresh rate monitors are nice, but that's not what Freesync and G-sync are targeting. Any of the adaptive-refresh rate protocols target situations where the frame rate drops *below* the full refresh rate of the monitor. Without adaptive refresh you have the choice of incomplete frame rendering (tearing) or stuttering with traditional V-sync.
So basically, G-sync & Freesync are there to improve situations where your framerate is still somewhat playable (e.g. 20 - 50 FPS) but below the full-refresh rate of your monitor. Obviously if you can hit a frame rate that maxes out the refresh rate none of this is important, but that's not possible to do for all situations.

I'm sure Freesync will come some day, but I'm sure AMD sees it as a low priority for Linux (possibly lower than Crossfire, I'm not sure).
