Weird performance / input lag

[[MA]Jinx]

Hello all,

 

I've got a Core i5 3570K CPU, 16GB RAM, and an nVidia GTX 580.

I'm finding the performance of this game a bit weird and disappointing.

 

On Medium settings, 1920*1080, VSYNC OFF, I find that FPS is quite good, probably around 40-60. But it FEELS like VSYNC is ON even though I turned it OFF.

There seems to be a quite noticeable input lag. It's a bit noticeable even in the main menu when moving the mouse.

 

Most noticeable though is it when loading up a simple mission and get to cockpit.

My TrackIR, which is always snappy in other games, seem sluggish and input laggy. Like there's some "smoothing" beeing applied to my head movement.

And I use the exact same profile in the TiR software, that I use in DCS.

Same goes for joystick input. I move my joystick, and I can see that the virtual stick in cockpit is actually moving like 100-200ms AFTER I move the physical joystick.

 

Usually when there's input lag in some games, it's either related to VSYNC, or too high gfx settings.

Then I usually just turn off some of the more advanced graphical features, like SSAO/HBAO, Motion Blur, FSAA/MSAA, Depth of Field, and other HDR effects.

Keep Textures high though.

 

In BoS, there's nothing like this. No advanced gfx settings.

 

I tried playing the game on low, which improves the input lag, TrackIR response, but not by much, and the game now looks like crap, especially textures.

 

I've so far found no ini or cfg files regarding advanced graphics settings to fiddle with either. 

Does ANYONE have any tips on what to do with this issue?

I disabled the cinematic camera effects since that seemed to make TrackIR smoother. My rig is similar to yours but I use a overclocked GTX 680 and I can run on highest setting but I had to turn Vsync ON because of screen tearing.

 

I run my 3570K at 4.2 GHz. How much OC have you applied to yours?

I don't think the speed of the CPU is relevant, this game seems to be GPU-bound. I have an older i7 at 3GHz and a GeForceGTX970 and I'm above 60fps at a resolution of 3240x1920 (three screens with surround).

 

To the OP:

 

Regarding input lag in the menu, if you are running 40fps in game, you are probably at 30fps or lower in the menu, which will show a noticeable input lag.

 

Regarding vsync and input lag, check your settings in the nvidia control panel. It's possible to override a number of game settings, including vsync. Check also if you have triple buffering enabled. If so, it will increase input lag a bit. Finally, as was mentioned above, turn off cinematic effects in the camera options. That also controls a somewhat nauseating motion blur effect that gives the impression your pilot is drunk and can't see clearly.

Thanks for your replies. I've already checked the nVidia control panel. No triple buffering and vSync is set to off.

The "cinematic effects" is disabled in game, although I must say I didn't really see a difference. It's stated that it applies the the external views only.

Still seems to be a motion blur being applied when I turn my head.

 

No OC on my rig. Don't think I've got sufficient cooling to run it OC:ed. CPU runs at 3.8Ghz in game by default.

 

 

Still, none of you guys know of any editable "advanced graphics settings"-file somewhere?

 

Thanks

Set in Nvidia CP max prerendered frames to 1, that will reduce input lag if it is a graphics problem, also speeds the mouse up in the menus  , just to be controversial, there is a thread where someone with triple SLI has shown that his system indicated the sim was CPU bound

I've already tried that setting. There's actually 2 settings in regard to prerendered frames. I've tried them both, in combination and by themselves. None of them had a noticeable impact on the input lag. 

 

Don't know exactly what you mean with the other comment. What controversy? I don't have a SLI configuration anyway so I shouldn't be affected by poor SLI optimization within the game if thats what your referring to.

This is actually one of the more controversial topics around this sim. There was a (bad) decision made earlier in betas to remove all ability to set individual graphics options and it's been hurting us since. The only option available currently is the terrain LoD setting and that's probably going to be taken away like the previous time someone found a way to make the game look and run better.

Yes, since buying the game yesterday, and playing for 30 minutes of which 5 minutes was flying and 25 minutes of going through all menus after an advanced graphics settings button, I've been on the forums and just reading up on the game. I've come to understand what they've done and now I feel conned and cheated. You kind of always expect these options with a PC game. Beeing able to tweak it to your liking.

As it is right now, the game which I paid 49€ for, is not enjoyable for me. The lack of advanced graphics options makes it impossible for me to turn off some of the costly eye-candy my gfx card can't really handle. This results in a very noticeable input lag, (more so than actual FPS drop, which in itself I find a bit odd) both with the joystick and TrackIR. Had I known this, read up on the forums before purchase, I would not have bought the game in it's current state. I will also not recommend anyone of buying it until they make it possible to fine tune eye candy vs performance.

To follow up on my original post. I have now invested in an nVidia GTX 980. Thought to give BoS another try. Sadly, the input lag with TiR is till there, no matter if I max out gfx settings or choose the lowest.

I come from playing DCS mostly, and some ARMA 3. In both games looking around with TiR feels instant and responsive. But in BoS it always feels like the view is lagging behind when turning my head. If ever so slightly this feels like the in game view is tethered to my TiR with a rubberband.

 

I use the same TiR profile for both games (DCS/BoS).

Latest nVidia driver.

Maximum frames render ahead set to 1 in nVidia CP.

Triple buffering off in nVidia CP.

 

Does ANYONE have this problem? Or maybe people are fine with it?

i think u gotta keep tweaking, no issues with TIR/input lag here..

 

i run it at 2560.1600, ultra, 4xaa, 4xdistance, SSAO on, HDR off, vsync off in game, adaptive in NCP

 

make sure u uncheck full screen and run it in native res for your display, made big difference for me

 

get 50-70 average, occnly 30-35 on the ground now with all that grass...

If I still get TiR input lag when I run the game on lowest settings I don't see what more tweaking I can do. But sure, I'll test running it NOT in fullscreen, as that seems to be what you are saying, and report back.

 

Do you run DCS at all so you can make the same input lag comparison?

[KoN_]

Go into the game go to settings and you will see " input  devices"  go to "noise filter" drag the bar  too  0.46 .

play around with this .

if you have it all the way to the right 1. your devices will lag try it , then bring it down so you get a good feel .

 yes, fly DCS about 20% of my time; no issues there either, as far as I can tell...

If you have an ssd you might need to clean it up. When they get close to full they start to lag games, programs, or anything that is on the drive.

 

Other than that I'm not sure. My issue, which was similar, had me buy a whole new PC just to find out all I needed was a reformat. Too many years of driver updates and random things. Sometimes you just need a good cleaning.

any overlays?

Deselect "Full Screen" in game, it improves Trir greatly.
