Need advice on setting for my EVGA GTX 670

[Gunnergolly]

Hello

 

Today i installed a new EVGA GTX 670 (http://www.overclockers.co.uk/showproduct.php?prodid=GX-195-EA) into my computer replacing my old EVGA GTX 580.

 

With my old 580 i used Nvidia inspector to set the vertical sync to 1/2 refresh which kept the FPS at a stable 30 in nearly all situations.

 

The problem that im having with the 670 is that when i select the 1/2 refresh rate option all is well until i turn the shkval on and then i get a lot of what i call Vsync stutter when in the cockpit view.

 

The FPS remains at 30 and the GPU usage is only about 60% (temps 52DegC) so the card is not really being pushed hard but for me the sim becomes unplayable.

 

If i don't use Nvidia Inspector and use the in game Vsync setting then i get very smooth frames at a constant 60 FPS, until for whatever reason the FPS drops below 60 then i'm getting the Vsync stutter again.

 

I've tried Rise of Flight and BMS and getting good results with those titles, i'm getting good results with DCS too, but i just can't eliminate the Vsync stutter like i could with the 580 by using the 1/2 refresh rate.

 

I've tried many combinations of settings and a couple of different driver versions (currently using 310.9) but nothing is working :cry:...

 

I'm half tempted to re-install my 580 and RMA the 670 even though there's nothing wrong with the card.

 

So any advice on what settings your using for your 670/680 or suggestions on things to try would be much appreciated as i'm running out of ideas !!...

simply set V-sync on in-game ( make sure it is set to app.controlled in your gpu setting)

and change line #331

in ...\Eagle Dynamics\DCS World\Config\graphics.cfg

to :

 

MaxFPS = 29;

 

this will cap your fps to 30 and prevent any corruption.

 

(...29 because DCS starts to count at the beginning of each frame, and not when it's finished , and the beginning starts with a 0 - and when you count 0 to 29 you get 30 )

 

Well, I don't use a Nvidea GPU and I can't tell you why your program fails...

but i can tell you that it's the best to make changes yourself where they occur , instead asking a "man in the middle" to care about it.

Thanks for your reply PeterP, i tried your suggestion for settings and whilst it's a little better im still getting noticeable Vsync stutter.

 

After a lot of testing (messing around) i have eventually settled for capping the FPS at 29 in the config.lua file and using Nvidia Inspector to set 1/2 refresh rate.

 

Flying low over Butami with my Shkval turned on is quite smooth now with the occasional stutter but i can tolerate that.

 

I've now started using your MOD for the "Unchaining the rudder" within BS2, flying the Shark is much easier now :)...
