I ask again... Has anyone noticed a significantly less VRAM usage with DX12 yet as promised?

I haven't.

Speaking of which, can anyone confirm that the ice on the lakes has been tamed in the affected areas?

Not lakes but - comparing NZ Milford Sound to a few days ago - there's no longer any ice on the inner part of the fiord.

I'd say three big ones, all equally eligible for most impactful improvement 🙂 1) Ground handling

I'm pretty confused about which planes are affected with the new ground handling.  This post in the official MSFS forums states that only the C172 and Cabri are impacted by the new changes in the ground handling.

When I read the patch notes, the patch notes say these are the changes for the ground handling:

Quote

Ground Contact Resolution Improvements

• More accurate ground contact model.
• Optional soft ground collision model for tires / flexible gears.
• Enabled new soft gears on C172 and Cabri.
• New high accuracy physics system to enable vibrations and micro movements.

And then in this thread, Matt Nischan said this about the ground handling:

Quote

The new ground handling model is opt-in for developers and must be enabled and tuned in the aircraft CFG files, in order to keep backwards compatibility. Out of those aircraft, only the 172 has received these changes. The other aircraft are still using the previous model.

So even in the patch notes, I assume the "More accurate ground contact model" and "New high accuracy physics system to enable vibrations and micro movements" isn't universally applied to all the planes? Meaning, only the Cessna 172 G1000 has benefited from the new ground handling code, right?

It's very confusing for me because I am reading in this thread, somebody reported that even the PMDG 737 has different ground handling now in this SU 15 Beta, but that can't be possible if the PMDG 737 doesn't have any of the new configuration variables enabled to take advantage of the new ground handling in SU 15. Matt Nischan clearly says all the other aircraft are using the previous ground handling model, which makes the reports of the PMDG 737 having different ground handling in this Sim Update, very, very, confusing.

Ya it's a bit confusing, but as Dutch (of Milviz) reported above and also some others about the PMDG, it looks like a subset of the ground handling improvements benefits *all* aircraft? But to fully take advantage of all the ground handling improvements in SU15 the aircraft devs need to implement/enable and tune the 5 new FM parameters for their aircraft. At least that's what I'm getting.

Ahh cool. @MattNischan , sorry to bother you (cause you are probably busy with the SU 15 beta and making the MSFS avionics even better), but if you have the time, it would be nice to know if there is a subset of the ground handling improvements in SU 15 that is benefiting all the aircraft.  From the patch notes, perhaps "More accurate ground contact model" and "New high accuracy physics system to enable vibrations and micro movements" are being applied to all the planes but we are not sure. Thanks Matt!

I think this might be the case. Experimenting some more - the ground handling does seem improved, especially on take-off / landing rolls. I´d like to hear some RW pilot’s take on this though.

Just for fun, I transplanted the 5 lines from the C172 G1000 flight_model.cfg to the C152 and I got similar results.

Excellent!  I will try some as well.  

Now all we need is some bright spark to write an app to bulk modify the text to all of those config files.  I await the file drop on FS.to.   It will need an exclusion list of course just in case, as we don't want to mess up the Comanche or the Fenix.

This can be done.  I used to have a camera position program that did it in FSX / P3D if I recall correctly.  EXDok was it?   EZDok.

Glad the overall feedback is positive with this update, I'll wait for the official update as I don't have much time to give to the sim for the next few weeks anyway.

Also, just a mention of a recent pet peeve of mine - the words "I'm getting butter smooth performance" followed by "on my 4090" is really getting on my wick. Yeah guys, we know. 😁

Been having some fun, experimenting with transplanting the new G3X into some other aircraft.

Very mixed results:-

Airfoil Labs Bristell B23

PFD performs flawlessly. MFD is blank.

Orbx Blackwing

Both units appear to work flawlessly, but Orbx must have applied some sort of 'glass' / screen filter to the screens, as they're barely visible (very very dim), even with the G3X's lighting on max. Not usable yet.

SWS RV-14

This one is not mine - it's already on FS.TO 😎  PFD and MFD work perfectly but only using the G3X's internal nav (obviously no connection with the GTN750 at this point).

Lightsim TL Ultralight Stream

By far the best result.  Works flawlessly (single screen plane), using the panel.xml from the NX Cub (also single screen). Navigation and AP both working perfectly.

(I need to make tweaks to the XML to set the RPMs up for the Rotax, and the green speed tape to 130kts).

Most aircraft are going to need some tweaks by the devs, which understandably won't come until SU15 goes to release. It may be that some modders, more experienced/skilled than I will be able to get some 3rd party aircraft working with the new unit.   The Orbx Blackwing would be top of my wish list.

now it is even smoother than butter because not only do we 4090ers have great fps, but now everybody, incl. those without a 4090 gets more constant frame times, resulting in less stutters. due to better thread optimisation, independent of GPU but better use of multicores and memory management. I am still waiting for x-box users feedback.

They CAN yet improve performance even more in MSFS 2024

how can it be smoother than smooth and more constant than constant frame times? this is near text book quality. what is needed now is better multi threading for non-graphic extensions like AI and ATC.

I think it’s time to introduce new metaphors 😂 But you’re right of course, the improvements should be across the board, frame gen or not.

I activated the VL-3's autopilot by changing the Autopilot=0 to 1.   Then activated the AP in flight.  The AP worked (with all standard commands) but there was no FMAs on the G3X.

You need to also configure the G3X in panel.xml. Docs here: https://microsoft.github.io/msfs-avionics-mirror/docs/g3xtouch/panel-xml-tag-documentation#autopilot

Does this mean we should turn on hyperthreading in the BIOS?

I don’t see why not. Even though some threads are maxed out, all threads on my 12900 are used (DX12). HT will increase CPU heat though, so it’s good to have some headroom on cooling.

I'm going to have to defer to the experts, I'm afraid. I may be mistaken, so best to wait for an answer on the official forums.
