Not your regular VSync storry! Any input appreciated!

[Pr3di]

Mornin` guys,

As a starter, I want to mention that I recently sold my Asus R9 280X Matrix in order to go for a 2-slot GTX 970 (the Gigabyte G1).
Now, on the AMD card I always had VSync Off, and never noticed any screen tearing.
With the 970 installed and the latest driver from the Nvidia website I noticed tearing from second 1, so I enabled VSync in BF4, which led to a CPU usage between 30-50% and GPU usage between 30-45% to maintain constant 60-61 fps.

Now, by curiosity, I wanted to check what average FPS I could get with VSync Off, so I turned it off in the game as well as in Nvidia Control Panel and rebooted to make sure the settings take effect.

Now here`s the dilemma: With VSync Off in both game and Nvidia CP, the FPS is still at 60.9-61.1 all the time, and the usage the same as before.

Does anyone have any idea why (it seems) is VSync still ON since I turned it off already?
The temps of the GPU while in BF4 at Ultra with VSync supposedly off are 41-42 C.

Since Nvidia manages individual profiles for each game make sure you also turned VSync off there, can't guide you where exactly since it's been a while I used a Nvidia card, otherwise someone else can guide you.

"The temps of the GPU while in BF4 at Ultra with VSync supposedly off are 41-42 C." How are you measuring this? That would be an idle temp.

I gather your build is in your signature (except for the 970).

Not sure if this would be it. There are two tabs in 3D management, make sure you're turning Vsync off under global settings in case program settings was selected accidentally.

I`ll check that @boju.
@i7baby, I`m using MSI Afterburner while in-game to check the temps and usage.

Edit: Signature updated.

OK guys, so the mistery continues!
Vsync off in-game, and in Nvidia Control Panel, both Global and Program settings.

In-game the same 60 - 61.1 FPS at far from 100% usage of both CPU and GPU.

Any ideas anyone?

Weird.

Try 3DMark or any benchmarking tool with an FPS counter and see if it is indeed your system and not the game. If Vsync was universally dodgy it will play up there as well.

It might have something to do with DSR, can find it in Nvidia CP and Geforce Experience. I think DSR is off by default in NvCP, not sure or whether Geforce Experience changes that if clicked optimise BF4 - If you've ever used this program.

 

[Pr3di]

Thanks for that boju.
I tried Heaven, Furmark and BF3, and none are FPS locked.
It seems that only BF4 is locked by this.

Unless anyone has any idea why this would happen, I`ll move over to the BF4 forums for investigations.

And I`ll post a fix in case anyone stumbles into this: gametime.maxvariablefps 200 (in console)

Is there a feature to enable/dsable vsync in BF4?

"You can reduce the input lag of VSYNC by capping the in-game FPS just below the sync rate of your monitor.

Go into your BF4 settings file and find the 8-digit number next to "GstRender.FullscreenRefreshRate" - cap just a hair below that number. If you still feel the input lag - go just a hair lower until it disappears.

By hair I mean decimal points.

My 75hz IPS is: GstRender.FullscreenRefreshRate 75.025002

So If using VSYNC i'd try a cap at 75.012501"

So maybe you've got it capped.

There is a Vsync option in BF4, but it seems that after some update, the settings for "gametime.maxvariablefps" was 60, so even with Vsync off I would be capped at 60.
Thanks for the tip, I`ll check it out.
