I made the same observation yesterday in VR and I’ve spend quite some time investigating further.
TL;DR: To me, this problem is due to the massive number of vertices the game is uploading to the GPU VRAM.
Using the dev mode tools at LFMN, it appears to me all the 3D objects in the airport are all LOD0 to get started. This means the tall light poles at the other end of the airport are displaying with as much polygons and texture details as the one close to you. And this goes for all airport buildings too.
I’ve also already documented the CPU/GPU stalling problems since the UK release, where it was starting to behave as if they’re batching lots of vertices at once to the point it takes longer than the frame time and makes the rendering skipping frames (hence stutters). On top of this, I’ve also noticed since the UK release the rendering engine is more often than not over-subscribing the VRAM amount in pushing too much data while the previously discarded buffers are still present in VRAM.
This sounds to me like the DX12 code changes creeping in the DX11 code branch, and causing this kind of problems. In other words, some of the GPU buffers and VRAM management code is managing resources appropriately for the DX12 memory management model but when running on DX11 it is causing a certain number of problems and conflicts with DX11 own resource management.
This is just speculation of course, but the visible effect is letting me thinking this is similar to what I’ve described above.
You have to be patient, for many of us this game has become a strange mix of love / hate, I like to think that the main function of the forum is to help, not just to complain
This shows what I’ve tested so far since this hotfix. Excluding everything and going 100% vanilla, even without my hardware connected, gives the same results. I have no edits to any config files either.
This PC had a fresh install of Windows a few weeks ago (post SU3). Outside of drivers, Steam, MSFS, and my other games, there’s little else installed atm.
It’s been stress tested, benchmarked, etc to ensure stability and speed. It passes all tasks with flying colours. Except MSFS.
While people with far lesser configs are playing happily, there are also many others with far higher end systems reporting the same problem I am. And the common thread here seems to be WU3 was our turning point.
Wow. This hotfix did wonders for me.
I just had a flight in FBW A32NX (newest unstable build), and I have never seen such good performance before. Cockpit view 40-50 fps and external view in the 70’s, even hitting 82-83 fps a couple of times. This is at 2560x1440 and a mix of high and ultra settings. A few minor stutters just before ATC or my co-pilot starts talking, smooth otherwise.
I had one major freeze/stutter-party for 10-20 seconds, and I was expecting an imminent CTD, but it recovered and I finished the flight without further problems.
if Asobo respects the official To-Do list (take a look at the home page) it arrives within 2021, hopefully…
it’s the only thing I’m missing from the old FSX
Hello, with this update I got the stutters back. Everywhere in Europe I have now stutters.
With version 1.15.7 everything went smooth, but now its nearly unplayable for me. Please fix those stutters.
It would have been, but then I’d have to answer another question, and another, and another. I learned how to teach myself things. Is it too much to ask that others do the same?
That’s exactly one of the two issues that were “hotfixed”, as mentioned in the “News” here in the fourm
The other issue was that “if you watch the Real Time Cinematic (RTC)” sequence to the end (who does that anyway? ) then the cockpit should now remain responsive.
It happens the same to me. ONLY at Nice Airport, and ONLY after the latest update, I have stutters while using the external views. Never had an issue before.. Is there a way to fix it?
I had CTD’s in the LFTZ area and it turned out I needed to update LFTH (Toulon Hyeres) from Azurpoly to the latest version. It’s a bit further from LFMT but well in the area and you didn’t specify the approach. Otherwise it’s worth checking if you have other addon scenery near LFMT.
(take a look at the home page) it arrives within 2021, hopefully…
