MFS Sim Update 3 stutter fix - Virtual memory settings...

[craigeaglefire 197]

this works on my setup,

9700K 32GB 2080Ti

Sim Update 3 gave me terrible stutters,

i noticed on HWiNFO that was using 97% of physical RAM,

FIX: reset the W10 Virtual memory from Auto (allocating 10GB Virtual memory) to Manual:-

(using C 512GB M.2 drive with 120+GB of spare space - BE CAREFUL!!!)

* minimum 20GB (20000)

* maximum 64GB (64000)

RESULT: stuttering & throttling of page file swaps eliminated > smoooth flights in hyper dense areas...

YMMV

Interesting, will try this.

Hi

i tried it. Actually I only had 32000 for all drives set manually on Drive C:. My MSFS is installed on E:.

I set the same VM as you did on E (I have 32Gb RAM and 2Tb MVMe).

so far not a single stutter that I’ve noticed. This is in the PA28 JF Arrow III in Oz. This had severe stutters yesterday followed by CTD.

fingers and legs crossed....

thanks

I haven't even checked my virtual memory settings yet.  Still managed by W10 as I recall.  With 32 GB of physical RAM, I wasn't expecting any issues in this area.  I have lots of space on a new M.2 1TB drive, so certainly can't do any harm to try.

I thought most stutters are caused by the main thread utilization being higher than usual? Or maybe there is a correlation with both?

[Bunchy 227]

I had a look at setting virtual ram (paging file) and the advice I found was to set the initial size to 1.5 x your ram amount and the total size to three x ram amount.

So for 32GB of RAM that would be 49152MB for initial and 98304MB for total. (Based on 1024MB per GB)

That is how I've set mine and I will report back if it helps.

It was a complete stutterfest at SAEZ in the WT CJ4 last night. Even after rebooting the sim. Bad stutters and 15 to 20 FPS.

I know that Asobo will fix this but if it works, it is a good temp solution.

Someone on the official MSFS forum said they thought it was due to memory leaks.
I will try this.  Might not be good for my SSD though!

Hi , 

Can someone point @ where we change these settings on Win10 ?

A bit more detail should be fine about how we do these changes? :)

Thanks for share of solution.

Kind regard.

Open windows explorer.

Right click on PC folder and select properties

This brings up the system window

Click on advanced settings, choose performance tab.

Click on advanced settings and select virtual memory 'change' button. From there you can deselect managed by system and input initial and total memory values.

 

You have to restart your PC for it to take effect

 

Hope this helps

I tried this prior to the update that has caused the fps issues, it has made no difference at all. I was advised to do this with the prior CTD issues.

[Bunchy 227]

Unfortunately, the virtual memory tweak does not do anything for me ☹️

Still a stutterfest at SAEZ.

Oh well......Bring on the hotfix, Asobo

this should help - my exact settings...

plenty of resource headroom now in London, New York, LA, Miami, Chicago with CJ4 having a blast in VR...

Yeah I thought so, I don't think it has anything to do with the memory. They really messed up something on the CPU side, if you look at the FPS windows in MSFS, you will the main thread utilization latency being higher than usual and then when you fly over photogrammetry or new areas that needs new Orthos, the main thread utilization latency goes higher and higher and thus the stutters increase.

In dev mode do you get "manipulators" spiking multiple times a second.

I am not getting the big stutters people have talked about but certain areas I get non stop spiking of "manipulators" combined with an FPS drop and micro stutters.   Fly a bit further and suddenly the  spiking of "manipulators"  stops and so does the stutter.

 

There is nothing obviously different about the places this happens but it is reproducible. I am wondering of it is a mesh issue ?
