Hi,

I have been struggling to change cockpit display FPS's via CDU (PMDG 737 Options Performance). I tried on all 737 line up but no success.

Is there something I'am missing ? I lowered the values to see the impact on my performance but other than ISFD FPS no displays' fps changes so do performance gain. 

It simply doesn't take any affect except on ISFD.

Any ideas or suggestions ?

Kind regards.

 

The text clearly states that it may not produce any more performance, and you should try turning down other settings in MSFS first, like LOD, etc. 

I think you'll have a lot greater impact on FPS by adjusting the setting within the sim itself: Options > General Options > Graphics (scroll to the bottom) > Glass Cockpit Refresh Rate.

MSFS glass cockpit refresh rate option doesn't have an affect on PMDG as far as I experience from my eyes and performance statistics. Can you check when you're able if I'am wrong. Low medium or high gives same smoothness on PMDG glass displays on my setup.

I optimized my MSFS settings as best as I can do with my current rig. I just wanted to see with the gain from lowering FPS on PMDG displays am I able to increase TLOD a bit more but anyway. Does anybody able to check if this feature works and changes FPS on PFD ND or any other display on their PMDG ?

What FPS are you getting now with the PMDG?

On the ground with TLOD 100 and 4K w/AMD FSR I get consistent 60 fps. Around payware airfields it drops to 50-55 in some occasions and cause stutters what I'am looking for to avoid by comprimising PMDG display FPS's if I'm able to.

3080Ti + 5800X3D

This is a flight sim, not a X box game. Payware FPS of around 50-55 , people on this forum would consider themselves really lucky.

Changing the PMDG display FPS isn't the right route to take, when you have a 3080Ti.    Any changes to FPS that do occur will be imperceptable.

I'd dig a little deeper into what is causing the stutters you refer to.   They're probably not related to FPS.  Do you use GSX?   FSLTL Traffic?   Both can cause some stutters (even at high FPS) in certain circumstances.

 

It's like rabbit hole trying different things for extra performance. I don't use traffic injection tools as I fly with IVAO. It only happens on the ground with payware airports and during panning mostly. Anyway, I think other than lowering TLOD on payware areas I don't have much choice. I wish we have dynamic TLOD changer depending on altitude that changing options during flight lowers immersion. 

You can also turn off First Officer displays 

I don't think LOD is the root of the problem. I can confirm that those PMDG settings do work for me but as expected, the difference is not that noticeable.

I had bad stuttering too in the 737-700 at dense airports when I was panning. Though I hate doing it, the only thing that helped in my situation was turning off Live traffic. I set AI traffic to about 25% in the air and 12% on the ground, no traffic add-ons. That's not an aircraft bug, it's the cap on sim objects that was added recently.

With panning specifically, if you have any of the 737 displays popped out and open on the sim screen that can cause a lot of stuttering too.
