Hi Everybody,

MS2020 stutters reduced by adding an additional experimental screen, how is this possible?

Is there anyone here at AVSIM that can explain why adding an additional experimental screen thereby increasing the workload of my hardware would make for a smoother view? This make no sense to me whatsoever.

Thanks
 

 

I've also experienced this same oddity at times -- more screens, heavier workload equal smoother performance. Go figure! 

Possibly due to the bottleneck switching from the CPU to the GPU - that would translate to fewer frames, but smoother CPU performance with no spikes and hence no stutters. Just a guess, but should be easy to verify through the dev tools. 

Forgive my ignorance, but what is an experimental screen?

Hi,

The experimental menu section of MS2020 gives one the ability to add extra views to MS2020.

Hi,

Changing the graphics settings doesn't change anything so if the bottleneck went to the GPU, lowering the graphics should shift it back. But no change. Also note, the bottleneck should affect all three visuals, not just the center monitor.

What do the dev tools tell you? Are you CPU or GPU limited? 

Also I think the real answer is only known to Asobo devs - the details of the graphical pipeline, rendering etc. As long as it works for you, that's great!

Hi,

It always shows CPU limited with the AMD7950X3D and Asus4090Tuf board.

Then you need a faster CPU😀
I've been flightsimming for over 20 years and I have always needed a faster CPU, so MSFS2020 just continues the tradition. I guess it is not easy, and if Asobo is able to make better use of CPU's with MSFS2024 that would be almost a miracle, but very welcome.

Observed this from the very beginning in MSFS: the more load you put on the GPU, the less prominent are those CPU-related stutters. That is why I simply crank up resolution scale until the dev graph mainly ready "limited by GPU" instead of "limited by main thread" and you get an overall smoother experience (sometimes at the cost of some FPS of course, which is in turn thanks to frame generation on my end no issue at all). 

Drawback with my 4080: you tend to fully load your VRAM, which in turn results in other stutters 😉 So the balance is quiet difficult to achieve imho, and personally I am not yet entirely happy. Has someone a good alternative to resolution scale for increasing GPU load when most if not all options are already on "ultra"? I do not...

Agree.  You make a good point and I have grappled with this many times.  You can use really high settings in many areas but where scenery is dense you have to wind them back quite a lot at times.  I generally use the higher settings unless I find I need to or know I will be flying in areas with high usage airports or photoscenery.

Hi,

I can make the setup stutter due to lack of resources, but then all three visuals stutter, not just one screen. I thought it may be a cable, but I swapped that out as well. I even went and swapped out the 4090 card.

I still think something weird is going on here and it's on 2020's end.

Thanks everybody.

2020 is infamous for needing the CPU and GPU load to be relatively balanced so neither goes into idle states.

Perhaps your GPU was under utilised and increasing the work load brought things more into balance.

Truer words were never spoken.

Back in the FS2xxx days we used to joke we needed the computer from the Starship Enterprise to run the sim with all the sliders turned up.
