1.5.6 ran nice.. this patch.. g-sync isn't functioning correctly for me..with v-sync off my fps will go up to 120ish, enabling v-sync limits my fps to 99.5 with my 100hz monitor but, while msi afterburner reports fps dips sitting still, from 99-75,

 

my monitor's refresh rate is dropping from 100hz to 30hz to 100 hz to 1 hz to 100 hz to 23 htz..

 

1.5.6 was running fine.. on highest settings with civ traffic turned off and shadows at mediumi MAYBE dropped to 35-40 fps low near active airfields at 3440x1440 but g-sync worked and it was consistant not jumping all over the place..and once I was in the air i was getting a steady 85-100 fps.

 

NOW even when in flight in the air, it's like it's constantly taking frame hits every other second and causing my monitors refresh rate to go from 100hz to 30hz every half a second and a short pause as if I were hitting pause for 1/10th of a second every other second. D3D in msi afterburner only showing a drop to 75 fps. That's not how g-sync is supposed to work. I've lowered water detail, shadows set to flat, no lens effects, no hdr, msaa 2x, AF 8x.

 

A day or two ago I was flying with maxed preload radius and max clutter/trees and everything but civ traffic set to high (msaa 4x, heat blur off) and though it caused an fps hit near the ground it was still playable and smooth, and again I was getting 70-100fps in the air, and I'd only see "70" when looking around Changing none of these options seems to fix the performance in 1.5.7

 

I've run repair.. I've deleted dcs from saved games.. the only other time I've seen anything similar to this was on a mission I created in 2.1 on normandy. I haven't ever experienced anything like this in 1.5

 

How do I roll back to 1.5.6? Because the f-15c campaign is not enjoyable with the game running like this. How did this make it to stable release?

 

*EDIT* 7-16-2017 After some experimentation.. I can see how this made it to stable release.. I'm only experiencing the issue flying missions in the F-15C Beartrap campaign.

 

Have not run into the issue in any other stock campaign/module. The game runs smooth even with the stand alone f-15c missions. And to be fair... I wanted to fly my F-15c because I had just fixed my Warthog.

 

I apologize for being slightly hot headed.. I'm aware my attitude could have been better. - Looking forward to a fix. Don't take my frustration as a lack of appreciation for the existence of a sim like DCS.. albeit.. I'm eagerly awaiting the day Cacausus and all the 1.5 content makes its way over to 2.X. You devs are working too hard. <3

Gsync on Win7 or Win10 ?

 

My guess is Win7, as in Win7 you can actually disable Gsync for either FullScreen or Windowed Mode, or both!

 

Make sure that the NVPanel is set to enable Gsync for BOTH modes.

 

Win10 takes a totally different approach as Gsync will run right when you load the Desktop.

My Gsync-LED turns RED ( that means: GSYNC ACTIVE ) right after logging in ever since I use Win10. It also does not matter on my end if FS or Windowed, Gsync is ALWAYS on ON.

 

Maybe that explains why...

 

Question: When you say your "refresh rate" is dropping.. What do you mean by that. That rate is usually FIXED and not dynamic or fluctuating, unless in proper Gsync mode.

I think you actually ment FPS, correct me if that assumption is wrong.

 

 

Download and install your proper*.inf file for your Gsync monitor. That may be mandatory to drive the screen properly. I have mine installed and no Gsync problems, never had any tbh, LOVE IT !

@headwarp, you can do a rollback like this:

 

Open a command prompt

Cd to the program files/eagle dynamics/DCS/bin

Execute the following DCS_UPDATER update 1.5.6.5199

 

This should rollback your install.

I run in windows 10 64bit.. g-sync is enabled in both windowed and fullscreen mode. This isn't on my end... this is because of the latest update. When the game WAS functioning correctly.. and other games do function correctly, including a sim from another small team of developers... and ED releases a patch where things begin to not function correctly even if it might be "fine" for you... perhaps jumping to the conclusion that this is user error isn't the right approach.

 

I understand you are trying to help.. But I've been building my own pc's and working with them since I was a child. My drivers are up to date.. my usb devices and harddrives are set to never power down while my machine is running... all of my drivers are the latest drivers for my hardware.. my system is set to high performance in power options, and so is my video card. I know how to setup nvidia control panel with each driver update. The problem only occurs with the latest update to DCS.. when the previous version was lovely. Thanks but no thanks.

Same issues. How many AI in your missions?

 

As many AI as there are in the F-15C Bear Trap campaign, which ran fine in the previous version.. as I'm about to roll back so I can do so. Thanks for the tip.

It's not the G-sync, it's the game that stutters badly with any slightly larger mission or something like that.

 

G-sync was not working correctly for me.. indicated by my frames per second reporting different numbers than my refresh rates, and by the framerate exceeding my monitor's 100hz refresh rate with v-sync disabled. That may not be the ONLY issue... but at least for me on my Acer x34 g-sync was not functioning correctly in 1.5.7

 

 

On another note..surprise surprise, reverting to 1.5.6.5199, sitting on the runway in my F-15c with the high preset, msaa lowered to 4x, AF to 8x, water and shadows to medium and heat blur off, everything else on the high setting..

 

I'm sitting on the runway getting a stable 99-100fps. Hey look at that V-sync is disabled too, and my ingame fps counter matches up with my monitor's refresh rate counter.

 

So again.. 1.5.6. runs fine.. 1.5.7 runs like crap. My machine is not the culprit.

 

Considering a lot of people seem to have issues with the latest updates to 2.1 as well where many people reported 2.0 running great for them.. my guess is ED has some digging to do to figure out what they're doing in their latest updates that are killing performance for many (not all) users.

 

*edit* stand corrected.. just the one campaign causing fps hits and g-sync to not be "syncing" anytime for me personally
