FPS performance - VRAM bug?

Hi,

My graphics are going in and out in terms of FPS like you seem to be describing. My system is pretty high end: Ryzen 7950 64GB RAM and 3070 RTX.

I also am not interested in degrading the graphics to get this to run smooth.

Any suggestions for diagnostics… I think my video settings are optimal and have the latest drivers.

Piece of junk… I volunteered for the alpha testing and never heard anything… they would have known… had they given me the chance. They are going to pay a very high price for this launch…

Same exact error, everytime im even at a gate of a big airport…
7950x3d
4080 super
64gb ram

Impossible with this specs im being “limited by mainthread” theres something seriously wrong in the game engine.

Running on TAA, i have tried DLSS even downloading the latest version but it still feels too much washed out for me. Having DLSS as an option in the game is no excuse for the devs to slack on optimization.

Im on a 7900x3d, 4080 and for the first time Im GPU limited. Always was CPU before. GPU utiization like 95-100%, while the CPU isn’t working very hard at all…
Strange.

And same with TAA. Have to use that. All other settings are blurry on my 5120x1440 res.

I just rebooted the application and it ran smoothly. You figure. First stuttering was at SFO and the second my local airport PAO… maybe complexity of database an issue?

Do you have the same issue if you follow the OP’s steps to reproduce it?
• Yes
Provide extra information to complete the original description of the issue:
• Cpu use low, Gpu use high, gpu temperatures high, Fps low, after some time the sim completely tanks and fps drop to below 10 even in the main menu. FS2020 runs with no issues

If relevant, provide additional screenshots/video:

Yep, me too. I bought the game expecting there to be a significant increase in fps and lower vram usage.

Same issue here.

I just did an 3h free flight with the A321, from LGIR to EDDH.
After landing in EDDH i saw that the textures werent downloaded. after the download i saw that the FPS dropped hard to about 20 fps with a lot of stuttering.
It seems that that caused by the Limit of VRAM. I think there are some hickups with VRAM in the sim. the sim showed me a usage of 15,7 GB of Vram. After closing the sim I saw about 1,7gb of usage on the desktop.

Update: Is it possible that the star airport AND an in buyed msfs2020 marketplace scenery will be streamed together into the sim? that could explain the heavy usage. I cant find an option to disengage streaming for star airports ect because it seems that this is binded to the marketplace which sadly doesnt exist at the moment?
But the VRAM issue seems to also happen at another, especially star airports, where you load about 14 GB into the VRAM.

FYI: i run in the ultra preset which should be fine performancewise (getting over the flight about 90-160 fps.

Pc Specs:
7800x3D
RAM: 64gb 6000mhz
RTX4080 (16gb Vram)
I run the sim in 2560*1440p resolution.

i tried it all, even mid default preset

but it bricks, it may take some time, panning around or setting up the plane but still bricks

on 2020 i could stay in dx11 sacrificing FG but all ultra and tlod 200 and happily be at 30fps plus even in the most demanding scenarios

i don’t understand why i need to degrade so much every settings just to be able to play (beacuse at 3 to 10 fps it’s a matter of being able to play)

Guys, now it is working at SFO. Here are the baseline Task Manager Performance readings at startup. Followed by a graphic at SFO. Then the measures during the SFO flight that worked.

What I noticed was it does not seem to be using the CUDA CORES. Those are used in all my other high end programs including image processing at work.

BASELINE:

SFO IN THE RAIN… LOTSA GRAPHICS

PERFORMANCE AT SFO… NOT MUCH DIFFERENT FROM BASELINE AND NO CUDA CODES.

I will check the graphics at the simpler airport but this is a stress test. I note that the SF Bay Area display list is missing a lot of secondary bridges and things for which I had paid previously.


I cant deal with this… There is seriously some kind of problem with this game engine.
As soon as i load in i can go around the plane and stuff and then suddenly i get that and i stop hearing my video card fans… after a while it “turns on” again and everything comes back

GPU mem used 16,9GB of 14,5GB.
Reduce texture resolution to medium - restart.
Tweak other settings if necessary.
Whats the GPU mem usage now?

yeah the vram is getting destroyed… but im running the same exact settings as in 2020… this is a very very very unpolished release… like they are laughing at us for writing all these posts…

7950x3d + 4080 super… how am i not able to almost max this out? Need to use DLSS because basically they are pushing it onto us

Yes. But 2020 you used dx11 I presume.
I used dx12 in 2020, and got used to having to tweak settings as it use a lot more vram.

Reduce Texture Resolution. There is 0 difference (almost). Restart and try again.

A 4080 in 4k in dx12 ms2020 or ms2024 you have to dial down something - texture res is best.
Try it…u wont notice the difference.

Exactly the same issue.

Specs:
OS: Windows 11
CPU: AMD Ryzen 7 7800x3d
GPU: RTX 4080 Super
RAM: 32GB
Bandwith: 900 Mbps

It happens to me also at not so big airports as LIRN or LIRP.

I was using DX12 in 2020

2020 DX12 was even worse in Vram usage, so some settings must have been tuned down there too.
So, have you turned down TextRes. Vram now?

Headsup, Hotfix deployed. It does mention about losing focus when changing control options.

I did some testing and it seems that the issue is greatly mitigated, simply by lowering the texture resolution from ultra to high.

Connection issues appears to be fixed, but stability I don’t see any improvement as of yet, with this hotfix.
