Posted September 30, 2014 I just watched the PCPer interview with Tom Petersen of nVidia, towards the end of it Ryan (who asks good questions a lot of the time) asked about how vsync and gsync behave in comparison to one another when the in game framerate matches or exceeds the monitor's maximum refresh rate. Let's take 60hz, if you use just vsync as is possible right now, there is a lot of added input lag or I/O latency however you wish to describe it, this latency is present all time due to the buffering of frames that is taking place. Now, with G-Sync, vsync is actually switched off in game while using it, but when the game is pegging your monitor's refresh rate (for instance 60hz) that same buffering that we currently see with vsync is going to occur, and that latency will always be present just like with v-sync which we all hate. So the situation is this, if you buy a 60hz gsync monitor and run it with a card capable of maintaining 60fps or higher during your gaming experience, you will be permanently stuck with the horrible latency just like you would be with vsync, the same will be applied at 120hz but obviously the latency will be cut in half as a frame is displayed for half the time. This is a potential deal breaker and a game changer for me pending further information, I'm not going to invest in this technology given this fact, if I had a card that can peg my monitor's refresh rate at all times and just use vsync, this would result in an identical experience and it was objectively stated to be the case in this video, I have timestamped the link please view it if you wish. https://www.youtube.com/watch?feature=player_detailpage&v=cr-GToUHino#t=6106 Link to comment Share on other sites More sharing options...

Posted September 30, 2014 how is this news? that was always expected, since this only alters Vsync at <monitor refresh rate...

Posted September 30, 2014 wasn't going to invest into G-Sync anyways so this doesn't really affect my choices this is like the fourth time this week i've used this photo, but Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted September 30, 2014 You think it's a flaw because you're not using the monitor right. Turn the settings up to use G-sync and not have the lag. . Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

Posted September 30, 2014 You think it's a flaw because you're not using the monitor right. Turn the settings up to use G-sync and not have the lag. that is if youre running less than the max refresh rate. otherwise, you will just get that small amount of lag (1/60th of a second max) between input and display. not something to be worried about, op is just exagarating his problem "Unofficially Official" Leading Scientific Research and Development Officer of the Official Star Citizen LTT Conglomerate | Reaper Squad, Idris Captain | 1x Aurora LN Game developer, AI researcher, Developing the UOLTT mobile apps G SIX [My Mac Pro G5 CaseMod Thread] Link to comment Share on other sites More sharing options...

Posted September 30, 2014 Do you realize how crazily apologist that sounded. Do you realize how smart it sounds to use something as intended? Oh my god it just makes sense. that is if youre running less than the max refresh rate. otherwise, you will just get that small amount of lag (1/60th of a second max) between input and display. not something to be worried about, op is just exagarating his problem Plus I think every g-sync monitor so far is 120/144 Hz. .

Posted September 30, 2014 I'm pretty sure you can remove the frame limit associated with v-sync without tearing, wouldn't this work for g-sync as well and eliminate the lag? Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

Posted September 30, 2014 running on 144Hz monitors with one of the fastest TN panels on the consumer market i was never interested in most of these thing, my monitors tends to refresh the screen so fast that i most of the time dont really notice screen tearing unless it gets really bad in normal gaming, i mean if you try to see it and pan around quickly to see it sure, but not in battle where i focus on other things Proud Member of the Glorious PC Master Race Link to comment Share on other sites More sharing options...

Posted September 30, 2014 It can be 3 whole frames, it feels nasty with vsync and people avoid it in droves because of it, and you are saying I'm exaggerating. no it cant be. where are you getting your facts from. it can be at max one frame and even that only when you input at the start of a frame, when you are already running max Hz. you either dont understand the tech, or you had a serious misthought about what it represents, because this is as natural as it was with vsync.

Posted September 30, 2014 Where does the lag come from then? from the fact that you input a movement/reload/whatever and its only displayed on screen the next time it is refreshed. so its always at max 1 frame. but with vsync you had the option of it being >1 frame when you were running at 30fps (2 frames max), 20fps(3 frames max) 15(4 frames) 10(6 frames)...

Posted September 30, 2014 Hence why I plan on buying a 144Hz GSync screen and never owning a machine powerful enough to breach that. Everything will be played on Max settings and it looks like everything will be capped at 30fps and recommended to run at 792/900p so we should be fine.....

So you'd be cool with playing a game on a monitor that became less responsive every time the refresh rate peaked? Link to comment Share on other sites More sharing options...

Posted September 30, 2014 I use a controller so I don't feel any lag but I can see this being a problem for people that use a mouse I hate using vsync with a mouse although if I turn my mouse dpi (cpi) up its not as noticeable.

Posted September 30, 2014 Author Because running a game between 100 and 144 is sooooo bad with higher details. framerate has peaks, so you're dealing with a monitor that has variable responsiveness as well as refresh rate.

Posted September 30, 2014 Author Explain to me the problem? you adjust your settings to target the average framerate at below the max refresh rate of the monitor, but there will be times when it reaches and exceeds it, and during those times the lag will manifest and the the responsiveness of the experience changes. Locking the framerate is point defeatist. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
