I spend basically half the day today in the Jetson One, my Oculus Rift S on my face and flying through Bretagne following the E5 long distance hiking trail with the help of GPX track loaded into LNM.

And then at the end as a bonus checking how fast I could be at work if I owned one in real life and would simply fly to work. 90 seconds is the answer.

As opposed to the 15 minutes I actually need with more mundane ways of travel.

(Now if someone wants to give me 8OK and convince the authorities that you can fly such an aircraft at roof level above residential areas, go right ahead.)

 

The performance improvements of SU3 are very noticeable on my system.

The most striking part was how crisp the TIN for my city looked. No loading in when looking around, no molten buildings.

Granted the Jetson is just a flying lawnmower with no avionics to take up CPU or GPU cycles, but being able to fly above a the high definition rendition of my home without a single stutter or visible LOD popping was quite a treat.

 

Towards the end I had a performance dip that I couldn't quite explain, but overall it was a very impressive experience.

is this 96GB RAM suggestion limited to your PC components configuration? or you think it might work in a wider range of different PC components like my PC spec in my signature?

Limited by the CPU IMC … for your 13900KS that’s going to be 2 channel, so stick with two DDR5 modules … doesn’t matter if it’s EXPO or XMP, most motherboards be it Intel or AMD will support either and if they don’t then just set the timings and/or frequency manually.

To be clear, you’ll not see major FPS improvements, the focus is the Low 1% where stutters and pauses live … but again to be clear, there are MANY factors that can trigger Low 1% frequency, running out of RAM is just one of many other causes.

many thanks for the clarification.

Because you still are.

No one except you was underwhelmed.

Well, maybe no-one posting here. But I can't claim to be particularly impressed, to my own great disappointment. Some improvements - it all looks a bit sharper, for instance. But still no real feeling of improvements with the LODs, and certainly no improvements to the awful PG tree obelisks. Plus a few newly introduced minor irritiations.

Still my sim of choice but I am feeling let down by it. This no longer feels like a bold new sim, and it's taking a long time to show signs of getting there and there is still a lot wrong with it. 

A lot right with it too, but I had hoped it would have matured a bit better than this by now.

Those will never improve until the technology to scan cities and landscapes improves further.

So I imagine not in another 20 years.

If it takes 20 years to enjoy a sim you have missed the boat.  That one left long ago.

I luv where flight simming is right now.

I did several flights post SU3. Initially there some issue with fps and graphics. I had to reset all my graphic settings to default, and then re-do them again one by one. Just like before I run everything on Ultra (DLSS). I had to come down on LOD though to get smoother experience on my RTX4090.

P.S. I finally decided to upgrade to RTX5090 . Card is on order will see what gives!

Hello Rob,

a way from FPS count and the 1% thing, I have a question on RAM utilization (in general) by MSFS,

My PC RAM is 64GB, total physical system memory utilization is around 41% while flying MSFS24, sim usage of physical memory was 12GB only, sim usage of system (virtual SSD) memory was about 27GB, available physical memory was more than 34GB (FREE), why doesn't the sim utilize that available physical memory and it prefers to use virtual (SSD) memory?

is limiting system virtual memory going to force MSFS to use physical memory?

That’s really a question for Asobo to answer.  From a software engineering side you can determine a systems physical memory very easily be it C++ Windows API call or .NET framework library call and I’m pretty sure even under WASM the host environment will support physical memory capacity device queries (but not always the case).  

In terms of MSFS 2024, the EXE is native but uses a WASM runtime and of course a WASI implementation.  WASI is the primary control of access to native OS resources.

On a side note, on average you will get a 10% hit on performance under WASM, it’s fast but memory address translation takes some overhead (no way around that for isolation/sandbox).  But WASI to GPU and I would expect the performance hit to be less … not expert here so take that with a case of “not sure”.

I would NOT limit pagefile size (virtual memory) and leave that alone to default settings.  TLOD and rolling cache size might contribute RAM usage IF enough RAM is available.  

EDIT: as for why MSFS 2024 doesn’t use your free 34GB could be related to many factors, but it’s likely Asobo would not allocate ALL available and would retain a certain amount of “free RAM” so as to not cause dynamic allocation from other sources/tasks the might be running on your computer.

And, it could also be a coding error on Asobo’s part … but that would be a stretch, that kinda RAM allocation isn’t something that a software engineer would miss since the tools we use to code with provide a plethora of metrics and memory usage is one of them. 

FYI, I have tested with and without using rBAR and the memory usage results are within 1% of each other.

What does that mean? Tree Obelisks ?

Palmtrees only show as their trunks. Making them look like Obelisks instead of trees.

And other trees just look like deformed Q-Tips.

Hi,

Anyone with the controls modified since SU3 final?

It’s crazy. Everytime I pick a plane I have to go to the control settings and redo my settings. I had a backup, but its completly useless!

Another thing. Screen tearing with Frame Gen is worse than before the update. I have tried everything: G-Sync on off, Vsync on off… you name it. Finally I have deactivated FGen. 
Thanks to my Rtx 5070 Ti that resists and mantains 72 fps.

Greetings

for the controls, go to the original airplane that you did set the controls for it, (make sure you select a proper device first, like joystick, throttles, pedals, and so on) right click on profile name, there will be a list, one of the choices is make this profile for all aircraft, or something like that.

good luck.

You want the good news or the bad news?  Pending on what hardware setup you have it can be both good news ... or you may look at it as bad news.  Probably not going to like what I have to report ... so you thought 64GB RAM would be enough?  Think again ...

LEMG (MK) + FSLabs A32x + GSX + AIG = 65.5 GB RAM (can see an FPS drop around the FSLabs A32x.

Verified with Task Manager 63.3 GB used out of my 96 GB ... I don't know your graphics settings, but I'm using the same as before TAA=200 everything on Ultra.

Slightly less RAM used with A2A Aerostar 600 - 59.3GB:

I don't know if your hardware signature is still accurate, but if you are running 64GB RAM, then it's very likely you are swapping to disk which will cause significant stutters.

I seem to recall a video somewhere on YouTube where MSFS 2024 performed better with 96GB of RAM which is why I went that route.

Sorry don't have the FNX A320, but from my testing the RAM usage seems to be the issue not the aircraft selected as the A2A was 59GB and FSLabs 65GB.

Rob.

 

I don't know what this is supposed to show, but you are clearly stuttering. Had you shown the frame time graph (as opposed to just the frame rate graph) this would have been more obvious. But even so, I saw your frame time spike up into the 50-60 ms range momentarily, which indicates pretty big stutters.

If you've set up a rolling cache of 32GB, then of course you won't see many stutters in subsequent tests performed at the same airport.

This is also not anywhere close to the most demanding scenario in the sim. Try iniBuilds KLAX + Samscene3D Los Angeles scenery with max traffic at native 4K and ultra settings.

I notice that it is really the little things that do matter. Finally AI and Multiplayer Aircraft have contrails and lights visible from miles away. Now I can actually spot the aircraft on final when I'm at the hold short point looking out for traffic.

Makes a huge difference when flying on Online Networks.

 

Edit: As I was saying, I posted the above while enroute. On approach, during a night landing, while I was on the base leg ATC asked me if I wanted a Visual Approach and if I could see traffic 8 miles ahead of me and I could see his lights. So I was able to follow him onto final, something that would have been impossible before SU3.
