Unexpected impact of slider / graphic settings on fps?

[Shomron 251]

Hi all,

I am using CS 757 iii and I am not able to exceed 25 fps with this aircraft although I am able to stay with my frames locked at 30 with other complex aircraft (see in my sig). I cannot exceed 25 fps even at cruise.

So after a hard a decision 😀 I decided it's time to compromise on my P3D v4.3 settings.

I started a flight in LatinVFR KMIA with ORBX Global/LC/Trees, UT Live, Active Sky & FFTF Dynamic as I wanted to do my tests in a relatively heavy scenario. I started at 7:00 so I could experience shadows as well.

From searching the forums I've found that the biggest fps killers are AG, shadows and reflections so I aimed to play with these sliders.

I managed to maintain ~23 fps on the ground in KMIA and ~19 fps in the air @~1,000 AGL with +/- 3 fps fluctuations with my default settings (see below) - 

Edit: I have use high resolution terrain textures OFF & dynamic lighting ON

HOWEVER, once reducing 1 slider at a time I saw no impact on my fps! Turning OFF shadows, reflections or reducing AG to None has not changed my fps! 😳

My specs are in my sig I have a GTX 970 & i7 4790K @4.4 (turbo boost) and have my frames locked at 30.5 in NVI only (locking my frames in-game always resulted in less fps and more stutters)

I am using the fast sync tweak in NVI as I use TrackIR as well.

Could this be related to the fact that maybe these are all CPU dependent settings and my actual bottleneck is the GPU?

 

Any help appreciated,

Shom

Bump, anyone?

Mine are all maxed and rarely get < 40 FPS  except at KSFO which spawns a lot of UTII traffic like 300+ aircraft.  Improving smoothness is harder than improving FPS IMO.

I am guessing you are using a complex aircraft...you also have better HW than I do

If you reduce those specific sliders are you getting even higher fps/ less stutters?

 

Thanks,

I also have i7 4790k@4.5GHz and GTX970. I don't have LatinVFR KMIA or CS 757. But for example on FlyTampa LOWW with PMDG 737 NGX I get around 40FPS. That's with target frame rate set to unlimited. If I limit frames I get like 20FPS, non stop stutters and it's not flyable. I also don't use dynamic lighting because I think 970 is just too weak to handle it and at the same time maintain good FPS.

Yep its the CS 757 which is performing low for me... same for the AS Airbus Pro at some conditions

I get the feeling I will need to upgrade my GPU soon enough

I might as well try maxing up those settings, who knows maybe fps won't go down as they are not going up...

Both my old 970 and now my 1070 have got lot better performance with unlimited frames on complex airports and aircraft  . I have same processor and overclock..

Shom, I find the biggest hit on performance in the control panel is AI traffic, and I mean a big hit. What is your AI traffic slider set at? My experience it shouldn't be more than 25 for airlines and 35 for GA.

I set it from UTL UI - to a target of 30 fps.

Any additional settings around AI to take into consideration?

 

Thanks!

Sorry, I don't know what UTL is. I HIGHLY suggest when flying an airliner, you set GA AI at 0, and airline AI at 25. When flying GA, set your AI slider no more than 30-35 and set the ailine AI slider to 0.

Ah, of course! I don't know how that works. But try the lowest setting you can and follow my suggestion on only using the pertinent AI for either airliners or GA, not both at the same time.

It's a mid - high range build flying a RealAir Lancair V2 and also the GTN750.  Memory is also very fast.  The SLI helps on Windows 10 for smoothness.  I have the sliders maxed because that is where I want them.  Also using a 4k 55" curved OLED that is a few years old.  Stutters can come at small (ORBX) airports like L05 when taxiing.

Will upgrade as usual but don't have a good buy signal yet.

Turned off all AI and there is hardly any change in fps.

Looks like the issue is around big airports - I can get down to 15 fps using a complex airliner. Above ~4000 ft I can get to my locked 30 fps (including CS 757 iii) as long as the weather isn't catastrophe.

I wonder if this is inline with my settings & HW? Maybe the GPU is limiting me?

 

Thanks!

Bean Sprout looks cool but hope the volume is low!  Biggest earphones I've seen in some time.

My quick 2 cents here, from the original post it seems related to the aircraft, CS 757.   Remember the overall framerate is somewhat akin to the weakest link in the chain, if all other things are equal, and the aircraft the differentiator, then...it may well be the CS 757 may need further optimization.
