V sync or not?

[markturner1960]

Hi, after downloading Syria, I was tweaking my settings to maximise frame rate a bit , previously, I had been using the sync option..... in ticking it seems to give higher frames, but I get some tearing when moving my head quickly, is there a way to reduce this without sacrificing my extra frames? My monitor refresh rate is 60hz

odd v sync should prevent tearing but you lose frames for it

Dont use in game V-SYNC instead try rivatuner framelimit or scanline sync

Use a Freesync/Gsync display. Or go for VR.

 

Nvidia settings have some options in between sync on and off. The best one I tried was called Fast sync.

I can confirm!

 

SLI System 60 Hz Monitor by DELL 4K

Setting it to Fast and turn off the Frame Limiter in NVIDIA Profile for DCS.

 

Make sure VSYNC is OFF in DCS game settings.

 

Cockpit 80-90 Frames at DCS Maxed out. No Image tearing whatssoever.

If you're using Adaptive Refresh (Freesync/G-Sync) then make sure VSync is also turned on in the graphics driver, but not in the sim.

 

It will clamp your framerate to the max allowed by your monitor, but will not introduce stuttering when the sim is running at the max FPS.

 

If you're not using Adaptive Refresh with DCS... then, you're on your own :) Besides, since you forked out a small fortune for a mighty PC, you should know how to use Freesync/G-Sync anyway. It kicks ass--use it! Used together with Vsync in the graphics driver, it produces the ultimate smooth, stutter-free and tear-free experience.

For ages now I have disabled vsync in DCS options and use the Frame rate limit option in nvidia control panel set to 60fps along with the Fast Sync setting, never a problem anywhere in DCS or any other game.

Adaptive Refresh is not an option if you use G-Sync. It's removed from the option as soon as you select G-Sync. You only have ON/OFF/FAST (latest nVidia driver)

Since I only have a regular 2D set up and TV Vsync and ensuring the settings keep the GPU capable of producing (in my case) the 60 frames required is the only solution I can find to reduce/eliminate uneven frame pacing. My system can knock out 120-200 fps plus at 20000ft but obviously when flying lower the fps drops and, without vsync, uneven frame pacing starts to become a problem under 90-100 fps.

 

I assume Gsync/freesync works differently but Im never sure what people mean by Vsync costing them frames. I can only think they mean when the gpu cant render the required 60 it cuts it to 30 even for just one of two frames (something not always apparent on an FPS counter that averages per fames over a second which is I guess why you see all sorts of numbers not just the 30 as the gpu flips from 30 to 60 even nth of a second)

 

Im also unsure if people (including me) fully understand what Fast sync is doing. According to a very boring and long video by Nvidia, on a 60hz its not giving you 90fps magically on screen. It giving you 60. The 90 figure is what the engine is kicking out into the flip flop buffers and fast sync is selceting the most recent complete frame to reduce lag. Fast is supposed to work best when you have twice the fps being produced as required by the monitor but ive seen some good results when this is not the case. For me however, its a stutter fest. Adaptive sync - pah - awful. Like looking into a water filled pessary dish you just tapped. Limiters also never give me a smooth experience since its not pacing the frames just imposing a hard ceiling and at 60 its too low a number to work.

 

Given my complete intolerance of uneven frames (stutter), I think i will always prefer a Vsync throttled GPU producing 60 even frames and some reduction in settings over a GPU thats kicking out frames unevenly making a numb FPS counter look good. Even if vsync does cost a few frames. At the end of the day and on a regular monitor once you are under the refresh rate, even for a split second, you are in trouble and its then only a question of how much judder you can stand.

Adaptive Refresh *is* G-Sync/Freesync.

 

You're thinking about Vsync, which is different--it limits the GPU render rate to to refresh rate of the monitor.

 

G-Sync and Vsync can be used together. I usually do. G-Sync does not limit the framerate to the max refresh rate of the monitor--that's what Vsync is for.

Yup, mixed it up with Adaptive VSync...:cry:

[Seal550]

I'm fine with Fast-Sync

Just observe the same scenario with vsync on and off, e.g. sitting on the runway or some place you don't normally get 60fps. You will probably see a 5-10% framerate difference. It costs gpu horsepower to do vsync. My understanding is that the gsync/freesync displays do that work instead.

 

Long story short, 90fps looks fantastic in DCS, but you will never see it with a standard 60Hz display no matter what the framerate counter says.
