Which is why everyone should make a test flight under tough dense scenery conditions, but in calm stable weather and take notes of fps in that short trip. And note stutters.

2. Install the beta patch

3. without turning on either DLSS or DX12 repeat the trip and compare.

4. For me some fps gain and no more stutters.

5. Turn on DLSS (quality setting) and large fps gain along with better visuals. 

I conclude the beta patch helps a lot, at least on my system, even without DX12 on. I don't see artifacts with DX12 on but if you do, just turn it off. 

I posted pics in other threads showing the fps display before the patch and after.

My system increased enormously with the beta. But, I was never  cpu bound before or after the patch. Alway gpu bound.

And then I upgraded both cpu and gpu. And still, gpu bound, never cpu bound at all. 

I'm gpu bound because I crank up the display options in MSFS until I do become gpu bound. Because I never want to be cpu limited.

I set DLSS to quality and moved the terrain LOD slider until I was only gpu bound at all times, and never cpu bound. I can't use terrain LOD as high as 400 on my modest system or fps would tank, so I slid it up to 240 and then was gpu bound under all conditions with OK framerates.

Render Scale is the only variable that can get me to GPU bound.  I run it at 120 w/ a native resolution of 3440x1440.

One PC builder states what he thinks is the most often performance mistake made by home PC builders (and sometimes commercially built) is to not setup XMP.

3:23 "most common mistake".

1:01:09 how to check if XMP is correct just by using Task Manager

Yup, this is probably the biggest thing.

Microsoft needs to add code to Windows to auto-check the XMP on startup and warn if the memory is running below XMP timings.

In decades of flight simming I have never seen a tweak that accomplished anything. 

Really? Not even in FSX?

I agree.  A properly tweaked FSX was a completely different proposition from the version straight out of the box, especially with Steve's DX10 fixer.  Fibre frame time fraction (or whatever it was called) set at 0.03 was also a revelation on my particular PC.

I was easily running 4k at 30 FPS towards the end.  Well, at least until the dreaded OOM caught up with me! 

Yah FSX had to be tweaked, the terrain settings and all that stuff wasn't all that adjustable in the menu.
FS-2020 is plug 'n play in comparison.

Here is the ULTIMATE TWEAK of ALL TWEAKS:

TURN YOUR CONTRAST DOWN, AND BRIGHTNESS

and if you didn't know -- how bright your monitor is should be mainly affected by the contrast control, but brightness also plays a part since it affects absolute black (but also often just above black due to monitor error).

Man, the new monitors of today are WAY too bright, it will blind you.
Sure having it brighter for HDR will look flashier, until you end up blind next year.

I am only running my monitor at 18 fL (62 nits), but sitting in the dark... Some might prefer it much brighter.

I wouldn't go above 25 fL (85 nits) due to eye strain, unless using HDR and you have every level set.
I don't have HDR enabled right now, will mess with it later after I decide which monitor I am keeping.

The $299 32" 4k Samsung has a contrast ratio of 2500:1 after calibration, was hoping for 5000:1
(but rare even with VA, need OLED but don't want to pay the extra $$$$)

The NDU trick was a good and reasonable one. Also this works and gives a 4-5% boost for every app on Intel CPUs up to the 11th Series.

I tried this last night and my sense is it's a bit better--I say sense because I already had excellent performance/smoothness.  Thanks ;o)

Can you comment on how your CPU is now in SU10 beta in DX12 mode, with regard to being CPU bound?  Is this better or worse now in SU10 beta?

Hey sorry about that, I was at work and didn't get a chance to check the forum.

The difference between DX11 and DX12 with the current beta is noticeable. I use RivaTuner to display a frametime graph, and there is much more stable frametimes with DX12. It feels smooth, similar to when X Plane went to Vulkan. There is a small difference in framerate, maybe 2-3 frames less in DX12, but the overall experience is smoother. Core usage appears to be very similar in 2D mode to what it was with DX11. The VR headset I'm using is the Varjo, and it brings the total CPU core usage up quite a bit but doesn't appear to generate much more heat. In VR with a combination of Ultra/High/Medium settings, I'm able to achieve 30+ situations in all situations with few exceptions. I don't notice a huge difference being CPU bound vs GPU bound like before. So to answer your question, I'd say it's better overall, but the GPU is being underutilized in 2D mode, which is a good thing for most people since there's more headroom for GPU demanding scenarios.
