Gsync worth it, for older eyes?

    Another chart Pure and simple marketing crap that makes more money out of the consumers, type in google ' Graphics benchmarker cheats' they both have don't it NVidia and AMD. also google 'Why Do We Need 120Hz/144Hz Monitors If The Human Eye Can't See Beyond 60Hz?' it's the brain, not the eye, does the seeing. Pure and simple and seeing with the brain is often called 'imagination,'

    The truth hurts the manufacturers pocket

    Just FYI, here's a youtube video I came across over the weekend, where someone tests input lag in fastsync vs vsync, and also discusses screen tearing.

    It's about 15 minutes long, but I think the guy does a good job on the analysis, and for me was worth watching:

    This is also a good test

    I think it should be obvious that if you fine-tune your monitor refresh rate and use frame good frame limiter like RTSS and thus can keep tearing line at basically the same level all the time then you won't get any tearing or stutter with FastSync either and avoid input lag that V-Sync adds. Of course this line likes to go very slowly up or down so occasional frame drop can happen but once in a very long time. And if there is fps drop then it will stutter but so will V-Sync...

    If person do Fast Sync tests using limiter at not refresh rate and then complain about stuttering then obviously this person have unlike myself must have low IQ.
    I do claim various things about things people did not thought of and they do often disagree... always however without actually testing what I said. The best way to get applause is to say what everyone else says, not to innovate :(

    If you own GPU that can do FastSync then it is a matter of finding that sweet spot refresh rate (for me it is actually something like 60.006Hz not exactly 60.000 - so you need to fiddle with refresh rate and find which works best) that make tearing line stay at as constant position as possible so that above and below it you have perfectly fluid motion and then turn FastSync and enjoy gaming in with V-Sync ON quality but with input lag like V-Sync OFF... as long as you have powerful ennough GPU that is (y)

    My wild claim #1 is: that because FastSync feels to be very responsive input lag with FastSync is the one you get below tear line (you see more current in-game events there) when doing V-Sync OFF. So if you have tear line period of one minute then once in a minute you will have one frame drop and game will sync itself to avoid adding input lag. This of course is wild speculation on my part and need further testing to prove or disprove.

    My wind claim #2 is that because at low FPS like for example 10fps FastSync feels considerably more responsive than V-Sync OFF below tear line there must be less buffering going on. Only thing that comes to mind is pre-render limit being at 0 in this case. You cannot set it to 0 since some time and many people reported new 1 is not old 0 and old 0 having less input lag and new 1 having the same input lag as new 1. This too is only wild speculation. The best I have.

    Interesting fact: with G-Sync + FastSync you still need to set fps limit to be a little smaller (2-3 frames) than refresh rate to avoid occasional frame skipping. Which is completely ridiculous because for example I can get perfect sync at 60fps with FastSync without G-Sync but I cannot do the same with G-Sync :hungover:
    Oh, and at lower FPS G-Sync do feel similar enough to non-G-Sync + FastSync (as long as frame limiter is divided by integer value) to to call it 'the same'. Though if G-Sync actually adds lag or not I do not really know. That said G-Sync is preferable because when there is frame rate drop it will keep everything smootch.

    Either way, in all games I tested so far FastSync + RTSS + perfectly synced monitor = great input lag reduction and no tearing and no stuttering and imho it is the good thing for NV users who 60Hz displays and also to those who have 120-144Hz displays without G-Sync as they can for example set 60-72fps limit to get fluid motion or even 40-48fps limit for more demanding games. Do what you want with that information.

    Oh, and if you have AMD card... shit f*ck out of luck I guess and go cry to your momma about it, not me.

    This is my last reply.

    It is pretty old test. We have 2018 now.
    And the way to use FastSync is to lock framerate exactly to monitor refresh rate, otherwise you will get stuttering and frames stuck in frame buffer waiting to be displayed.
    Neither BlurBusters not this Battle(non)sense guy tested this configuration. Such a shame :(

    Totally not true
    Sharpness is way better as you go higher Hz + higher fps and you get input lag reduction as well and eventual stutter is also reduced and if you use V-Sync OFF tearing visibility is also greatly reduced (y)

    4096x2160 makes enormous difference vs 3840x2160 (especially for watching 3840x2160 movies on it :cat:) and 144Hz does not make any difference vs 60Hz... you truly are a very strange guy... or girl... or whatever the hell you are :android:

    first guy can't = 1/5.

    linus can however = 5/5.





    I don't doubt that some people can tell. I think I could tell the difference between 75hz and 60hz, but when I tried 75hz and 144hz - both freesync for gaming - I couldn't really tell the difference. They both seemed incredibly smooth. If I took a window on the desktop and spun it around as fast as possible with the mouse I think I could tell the difference between 75hz and 144hz -- but in gameplay - nah - it just didn't matter to my eyes.

    Now - if you repeat that same test with freesync on or off, or gysnc on and off - I bet I'd be 5/5 too - as I can feel the vsync lag and sense the judder that occurs without freesync or gsync. Different people apparently see differently --- surprise.

    Everyone to there own opinion on the matter, Yes there is big difference with 4K @4096x2160 compare that with a UHD @3840x2160 for movies because you add 256 more pixels to the image that's if your TV/Monitor supports 4096x2160 if it don't then you are stuck at UHD level and it don't matter if it say 4K UHD because it just a UHD @3840x2160 near 4K,

    Yes I am male the last time I looked:) Been strange is better then perfect and always right in this world.;)

    Yes I saw the second part but it looked more scripted IMO, then the first part like most of his YouTube channels,

    the only strange thing in the second part was his friend would leave the phone on the desk face up every time to change the settings on the computer why didn't he leave it on the chair near the camera he must known what setting to change wouldn't he? OR linus facing the wall for that matter.

    Imagine linus got it wrong he would lose face in front of his YouTube fans so he would have scripted it & cut it again & again to get it right that is why the phone was on the desk. he might have got just 4/5 but he want to be perfect 5/5 like always.
