Vsync Tweak/fix: Gain the benefits without the input lag

setter · 12 Oct 2014 at 14:57

I think the bf series depend an awful lot on your connected speed. I'm on adsl at home, yet when playing on a lesser spec system on a fibre connection at a mates house. The difference is night and day. Much smoother and less frame drops. 290 based setup with mantle, yet dx is also fine on it, lower min fps which is expected.

I expect what you seeing is the Mantle effect tbh

it is that much better. "not getting into that though"

The connection speed I not sure about, What I do know is Battlefield has a lot of server side tech going on. If the server isn't performing right then the players will also feel the impact.

I don't know what the major differences engine wise are between bf3 and 4, but the former is flawless. The recent patch helped bf4 a good bit, but its still nowhere near as good as the CTE. On Dx its comparable to mantle in vanilla. Don't think mantle works in CTE yet though.

Maintenance on the 14'th, hopefully a server patch / fix.

Yeah Mantle does work in CTE its where I had to play mostly till the fall patch other week.

About the connection speed this year I have came from Virgin 120mb to Sky ADSL 6mb and back on Fibre Sky 40mb

I didn't notice any difference in gaming/online play between the speeds.

For me input lag is worse than tearing and this doesn't remove all the lag so I have preferred vsync off. It also felt less smooth but it was a long time ago when I tried it (when nvidia added the frame limiter to drivers).

I won't be buying gysnc neither until I have been able to test it first

Am the same I run Vsync off have done for years am now to the point I dont even notice screen tear.

Ive tested Borderlands 2, Alien:isolation and BF4 so fare and it works like a charm so im baffled why some of you dont seem to get the benefits of this method as its extremely simple. Maybe its because im using nVidia and the effect is not the same on AMD hardware, maybe its because im using an already low input lag monitor(not to confuse with display lag, or pixel response), i dont know, im just guessing here. I do know that if those of you who are not seeing the benefits were able to take a game for a spin on my setup you would understand why im so cheerful. I still think this is an awwsome tweak for those of us stuck on 60hz panels for whatever reason.

Doesn't adaptive Vsync do just as good of a job as this method?

Its not the case of AMD or Nvidia I have seen this method posted before and while most do agree with the reduced input lag, it doesn't stop the of bad effect of vsync like frame rate drops or frame stutter.

But it is true what you saying in the fact it does reduce input lag.

Adaptive Vsync makes games stutter, when the sync is switched on and off.

Never really noticed that tbh

Anyone here actually tried this? At work at the moment but would like to try this if I get back on COD4.

Well thats the thing i personaly dont get. I know how vsync is suppose to work, if the card cant keep an even framerate it should by design drop to half of that but my setup doesnt do that and im not using adaptive-vsync but only whatever the game itself is offering and i have no tearing and virtually no input lag. Perhaps im just lucky, perhaps the evilness of vsync will show itself in the next unknown game ill play but for now im seeing none of it.

Yeah it does improve input lag but doesn't eliminate it for me. Maybe our perceptions of the issue are different - for example in both BF3 and BF4 I can feel a level of input lag even with vsync off which I assume is inherent to the engine itself. Turning down HBAO seems to lessen the lag effect for me...

Ive had the same experience with some games such as post processing effects having some sort of input lag associated with them even though the fps has been rock solid above 60.

I use the d3doverrider and enable triple buffering, seems to lower the input lag and less of a jump when it goes below 60fps.

Both high levels of ambient occlusion (HBAO) and 4x MSAA or higher seem to induce a feel of input lag in BF4 for some reason.

Noticed this too, both with single card and sli. With the performance graph showing it spikes all over the place and feels jerky. If i drop settings to lowest, no msaa and AO off the graph is much flatter and it feels better. Yet youd expect that 780 sli should cope with this game with ease.
