Which filter did you end up using? 

Mine won’t fit yours as my monitors have custom settings also.

But this is a good place to start :

This is a very good vid :

This would likely be a fix for someone who had a corrupt driver install at some level hence so may benefit, others not so much.

I have always use GEForce experience and express driver instalation. Often I see advice to use these tools in safe mode to make sure the old drivers are removed totally - is this not needed nowadays!

Must admit I watched and followed the two videos referenced by Overkill.  Using MSFS developer to watch cpu/gpu usage, I normally see about 20-30ms for the cpu.  After following these two videos I am now seeing 12ms. I set my graphics settings to match his, so everything on ultra. My gpu is normally running at approx 25-28ms but after following the videos it now runs at 19-20ms.

My monitor is 2k at 144mhz. I have v-sync on in msfs set at 20, so I'm getting a steady 48fps.  This is the first time in two years since buying the PC I have done the clean graphics driver uninstall/re-install in safe mode.

I have certainly increased fps following the advice so I'm happy, but maybe I just had MSFS misconfigured or over-tweaked and it needed a clear out.

We have similar machines save you're CPU is stronger and GPU a little weaker.  Do a test for me if you will:  load up something like the AS CRJ700, or if you don't have that then even the default B787.  Keep all on Ultra, T-LOD 200,. O-LOD 200, and AF 16x, T-SS 8x.   Go to EDDF just let it load running on whatever runway is assigned.  Report what Dev Mode MainThread shows in milliseconds.  Thanks in advance this will give me something I can relate to.  Cheers

So we have a shader cache folder in MSFS ? 

I believe it’s part of the directx file cleanup in the windows recycle bin properties.

I only have the default B747.  I re-installed GEForce Experience because I use a couple of filters (no fps change observed). I changed my monitor refresh to 120Hz for a bit of headroom so I'm fixed at 40fps.

Loaded on RWY 7C at EDDF, clicked on fly and I get...

FPS - steady 40fps (ms just under the fps is 25.7-25.9)
Main thread is 19 - 22ms
RdrThread - 6 - 8 ms
Manipulators - 9.0 - 10.5 ms
CoherantGTDraw - 0.3 ms
CoherentGTUIThread - 2.0 - 3.5 ms
GPU - [20.3;28.3] med=22.3

CPU Mem: 6.279/31.919GB
Peak CPU Mem: 7.124GB
GPU Mem: 3.393GB/10.040GB

Hope this helps 🙂

So if I'm getting 70fps now I should get 80+ with this fix?

I regularly burn incense before I start a session with MSFS. Amazing improvement! So smooth!

I see now Ricardo's #41 incense is on a 25% off sale on Flightsim.to !

Thanks for doing that I appreciate it.   To confirm, you made all of these settings identical?:    All on Ultra, T-LOD 200,. O-LOD 200, and AF 16x, T-SS 8

Your CPU is ~8% faster than mine at our respective clock speeds.  Your display demands ~32% fewer pixels to render.  After I land in about 10min I will load up the 847 and test.  With the B78X Heavy Division I will see about 23-25ms in the MainThread if I recall so look forward to what 747 does.  This is all highly dependent on setting everything as described and most importantly T-LOD at 200 for this particular test.  Typically I'm setting this to 120 if I will be ARRIVING at EDDF, and 150 if departing at EDDF.

Okay here are our findings.  I set my 3440x1440 display up for your resolution thru NVCP and MSFS.  My monitor only does 60Hz max so I did one using the 60 divisor and got this--essentially the same as your result at 20.3ms, and again your Main Thread processor is ~8% faster at your clock speed.  For some reason your VRAM in use is significantly lower than mine which makes me wonder why.  You set all parameters identical eh?

Since I run 30 fps by Vsync using the 60Hz/30 divisor, I duplicated the test using this frame lock.  You can see MTms is around 20ms once again.  And again, GPUmem is much higher in my rendering.

I conclude from this simple test that this routine will have no payoff for me--and so I'll stick w/ my first guess which was that something was messed up w/ your driver install before you did the procedure and hence you're seeing improvement.  Perhaps others suffering from poor performance should try this procedure.

Cheers

Snake Oil 101.

this type of fix/tweak/repair/whatever you want to call it really isn't going to do anything unless there's a very specific problem already in place, and it's so unlikely now with Windows 10/11 being so stable in general compared to the old days. of course everyone should be aware of what services or apps are running and how much resources they consume (just a quick look at task manager is enough to get a good idea.)

driver install packages from AMD and Nvidia have been very reliable also and the chance of any sort of issue of corrupt driver install is extremely minimal unless somebody has been running the same Windows install for several years and has switched GPU manufacturers at least once.

the video also does not do even basic benchmarking before and after which means at best there is absolutely no way to confirm the so-called "results" and at worst opens the door for the placebo effect to kick in and convince everyone magical performance gains have been achieved.

Oh blast, I had the TLOD at 100 as recommended in those two videos!  I have changed it to 200 and have the following...

FPS - 38 - 39fps (ms just under the fps is 25.0-26.0)
Main thread is 22 - 24ms
RdrThread - 6 - 8 ms
Manipulators - 9.0 - 10.5 ms
CoherantGTDraw - 0.3 ms
CoherentGTUIThread [0.6; 9.0] 90%= - 3.4 ms (varies very slightly)
GPU - [20.9;27.3] med=23 (varies very slightly)

CPU Mem: 4.673 / 31.919GB
Peak CPU Mem: 7.124GB
GPU Mem: 3.929GB / 10.040GB

snake oil and click bait .. and a bit of overkill ..  😆🤣

I had clear skies when I tested so it that the difference in VRAM?  

Something else I just discovered - FSRealistic absolutely hammers the CPU!  I just took the FlySimWare C414 up to 26,000ft.  Throughout the climb my cpu performance was dropping.  My fps dropped below 30 and I went from GPU to CPU limited - quit FSRealistic and I went straight back to 40fps and GPU limited!

I did the full mod in the OP. It surely changed things quite a lot. FPS increased. MSFS now less gpu limited but more cpu limited. I had to crank up the render scale to get back to gpu limited because there were a few stutters when mainthread limited.

The OP shows running this mod will reduce the number of Nvidia Containers shown in task manager from 7 to 2. And it did just that in mine. The mod allows you to deselect a whole lot of background stuff that Nvidia downloads by default with the driver. The mod displays a whole slew of checkboxes and you deselect them all and only then download the driver. This means you don't get those Nvidia processes running any more.

 

I'm not entirely sure I like the effect of the mod as being mainthread limited is not a good thing, stutterwise. But FPS went up.

I tested in default 320 from JFK to flying over the skyscrapers. And the C152 default for a non glass display. FPS increased for both.

You can see my lowly specs. And a 2K monitor. I have the display preset at Ultra, both LODs at 200 and Renderscale at 170. The terrain LOD can be bumped up from 200 to 400 and Rendescale from 170 to 200, but it kill my performance. So I leave Ultra preset 200, 200 LOD and 170 Render.

Normal scenery I can stay at 30 fps, but in the Neo320 and NYC / JFK it goes down to 20 to 24. It was 23 to 28 after the mod. Flight was the same, take off JFK and fly straight to and over the downtown skyscrapers at about 1100 feet (down low).

Not flying the 320, I get 30 locked and it doesn't fall below 30 fps.

 

It's been 6 months since I ever saw 'mainthread limited' in dev mode fps. After the mod there it was. You may not like the changes, but it isn't a mod that does nothing.
