High Frames But Stutters

When I display FPS in DEV mode, I never see VRAM getting maxed out. Always have anywhere from 1-2gb free. 

1-2GB free is a very low amount of available VRAM because that's only what MSFS has reserved. Then means sometimes 1GB for any spare swap / background / Windows visual processes / any programs you might have running on other monitors etc.

Just a thought; I once had stutters because my chipset drivers and motherboard BIOS wasn't up to date... worth a shot?

Hi

I remember seeing this issue myself!

Where, not seeing this metric in MSI.

Try switching to 2K 2560x1440 and see what happens. I run my 4K at this setting and it's smooth as butter and visuals are fine, even with my blurry eyesight..

It's "memory usage". The other one is "memory usage \ process", but this one will just show the memory used by the sim process, same as using dev mode.

As an example, I'm parked in the airport now and Afterburner "memory usage" is showing  6.6GB used and in dev mode it just shows 5.1 used. Memory used \ process in Afterburner is showing 5.1 also.

You can also check in task manager, "Dedicated GPU memory" will show the same as "memory usage" in Afterburner.

The argument that the sim will use whatever VRAM is there is a bit flawed, because then nobody would ever have enough VRAM. In my experience, the sim is using around 14-15GB VRAM at the absolute most. And that was the case with my previous 3090 as well as my current 4080. 

As a sidenote, maybe this will be alleviated in the FS2024 version. Or at least I hope so. They were talking about that the system will download whatever textures you need, and purge the rest quicker. But FS2020 also does that. When they introduced it we had the issue where you would turn around and it looked like a nuke went off with things popping in and out of view. 

Sorry for the digression.

Try with Objects LOD at a lower setting too. Especially at larger airports with many objects you will get better performance…

Well, my experience aligns with that of @Noel, I’ve seen between 19 and 20 sometimes.

It always sucks when the sim was running fine before an update and after you have to adjust settings to get the sim to perform as it did before.  I had to lower a couple settings as well to get the sim to run as good as it did pre SU13.  At least visually the sim still looks good even with lower graphic settings, not even noticeable the change.😏

In my expericence, and I know this sounds counter intuitive but, I've raised my graphics settings to put more load on the GPU and give the CPU some headroom, this improved my stuttering immediately.

I'm running an 8G 3060ti with a Ryzen 5 3600. Most settings on High with a bunch on Ultra also and 1440p. I'm getting a consistent 35-45fps.

You can monitor your VRAM usage in Dev-mode when you are at big 3-party airports, when your VRAM capacity is overloaded, the bar will turn dark red and the stuttering starts despite good fps, 12 GB VRAM is not enough for me, and I only use 3440X1440, but the problem only occur with DX-12, with DX-11 there is no problem as the memory management is significantly better.

Try deleting rolling cache. Whenever I get way more stutters than usual that solves it.

This. Maybe I’m paranoid, but I’ve come to believe that the game does cache downloaded data even if you set it to not use a rolling cache. They keep it quiet but they do it to reduce data loads on their servers. Delete rolling cache at every game launch.
