I don’t fly with ATC I fly 100% vatsim
This means I don’t have airport traffic, live traffic, I don’t have ATC and ground vehicles
Only sim data that I use are live weather, PG and bing data. I use the Navigraph stand alone version with the simlink. I use FSUIPC7 voor flight data to be recorded to VASCARS and also Vpilot. Tried to fly with out them and I still suffer from frame drops. I think I it’s just Nvidia that don’t understands flight sim work flow and the GPU goes into power management mode if you look at THIS
The post I made this morning after trying to fly from Hongkong to Amsterdam look at the GPU, CPU and RAM. As if flight sim is not running. Why is that? I disabled CP limiter on Nvidea control panel… this is not a ram problem, this is not a overloaded CPU problem and sure as you can see from task manager, not a GPU problem. Why is that that if I go to details FlightSim is only using 2000 kilobytes of ram?
Does windows hibernate Programs that runs more than a couple hours? Is it something that Nvidia has in their driver that let the game not use as much resources as it should?
Computer performance is great and also the sim if I try the exits. Again. I would like to refer to the second part of This post to show you that everything is fine untill I try to resume flight again.
I went to check bios to see that I have performance mode on. And nod energy management.
I have a focusrite scarlet 2i2 this is for my sound system, microphone plugged in and head phones out I can master the volume with it, I also think it has it’s own CPU
If you let Windows manage the pagefile, it will grow and shrink depending on usage, which can lead to performance problems. The optimal size of the pagefile depends on your maximum commit charge, which is shown as “Committed” in task manager (while the memory hungry process are running).
The 30 frames thing only works if your monitor refresh rate is set to 60hz. Anything other that will only give you 50% of the refresh rate of your monitor. Hopefully that makes sense.
Anything other than 60hz will still probably be pushing the whole system very hard indeed for hours on end.
Not sure how this could lead to performance problems unless one is using a very slow HDD. The purpose of letting Windows manage the pagefile is to improve performance, not create performance problems. (BTW, if this is a performance problem, to prevent Windows from growing and shrinking the paging file, set the minimum and maximum sizes the same. Windows will allocate the space when starting and won’t change the allocation while running.)
And for MSFS, any use of the pagefile cripples FPS because MSFS needs real memory for performance. If any part of MSFS memory is on a pagefile, the performance drops significantly. And Windows starts moving memory out to the paging file when memory is around 55% to 75% capacity.
Regardless of storage type, I wouldn’t want Windows starting unnecessary background I/O while I’m enjoying my flight.
Certainly the more RAM you have the better.
I would say when task manager says roughly 30GB as the second number under Committed then you will be fine, but it depends on your workload. Right now it says 348GB which is way overkill and wasting a lot of storage.
With only 16GB of RAM, your primary goal should be to free as much physical memory as you can. Like PacificSet90456 said, you want to avoid disk paging as much as possible.
I only get this FPS loss over certain regions of the globe. For instance, I’ve repeated the following flights many times and cannot replicate the issue:
Honolulu-Sydney
Sydney-Dubai vv
Sydney-Doha
Dubai-Lisbon vv
Doha-Sao Paulo vv
Dubai-Sao Paulo vv
I get FPS loss in the following (100% repeatable):
If your main drive c: is a fast drive ( ssd ) and there is enough free disc space on it:
set c: min: 8000 and max 25000
– note: possible is also to set a fixed value: min: 25000 max 25000. This avoid a reallocation of disc space, etc.
remove the other settings for d: and e:
if your main drive c: is slow or there is less disc space on it:
set c: min 1024 max 1024 ( dont forget this limit in case you removed the second drive )
set d: or e: min: 8000 and max 25000
– note: if d: is also a ssd then choose better d: because you have on e: already msfs installed
Note that pagefile size must not necessary fix your issue, if this is caused by a mod or whatsever. If windows must use huge pagefile file then stutters can occurs " a file on a disc is just not RAM " .
In your screenshots we can see that you RAM is nearly fully used. Taskmanager show only the working set and not the commited memory. I guess in your case the MSFS commited memory more than 25gig. If this is the normal situation, because you may be use a lot of mods or tools, then think about an upgrade of RAM. And dont forget, adjust pagefile can avoid some kind of stutters, but not necessary these kind of stutters/perf-lost you describe here.
