Seems fine to me. First load of the Fenix went weird. But then it sorted itself out. Sublime flight with the RJ to Luton. AI traffic and FSLTL much improved.

Unfortunately for me, SU3 beta has been really rough - lots of CTDs, it appears my VRAM is frequently exhausted even near default airports.  But the moment I fly into one of my payware addons (typically a 2020 addon), my 4080's vram is just maxed without warning (I guess I get that annoying popup hehe)... of course this introduces lots of heavy stutters and I think is what eventually leads to CTDs.

I also see the whacky cargo straps/seatbelts bug again (where they show outside of the plane)

Additionally, dynamic registration is mostly working, but sometimes even the default aircraft show white boxes over the reg, or the reg itself comes and goes as you pan around the planes.  Seems like a LOD issue imo.

If you look at the 2024 beta forums, there are quite a few posts about CTD's since su3 beta was released.  At first I thought it was due to community addons but I've run without and I still am having CTDs.

But being a beta, these things happen, I'm sure it will get worked out!

I don't see people talking about this:

* Integrated full inertia tensor support, MOI re-calculation fix for weight changes, and rotational dynamics fix into the C172 and Extra 330LT.
* Added support for a full inertia tensor via the new “empty_inertia_tensor” parameter in the [WEIGHT_AND_BALANCE] section of flight_model.cfg (see SDK for details).
* When this parameter is specified, it also enables the following fixes:
1. Fixed previously unaccounted influence of payload stations on MOI changes. Note: if you previously compensated for this by increasing the empty aircraft MOIs, re-adjustment may now be necessary.
2. Fixed MOI recalculation during in-simulation weight changes.
3. Fixed rotational dynamics modeling: the laws of conservation and evolution of angular momentum and rotational kinetic energy are now satisfied with high accuracy.

I've had better luck with SU3, very smooth and no CTD's. I do have ReBar off which is helping with VRAM.

What's rebar?

Basically, rebar lets the CPU access all of a GPU’s VRAM at once, which helps in some games but not all. I find that disabling it for MSFS2024 reduces stutters, lowers VRAM usage, and improves stability. You can turn it off via the BIOS or Nvidia Profile Inspector.

Resizable BAR - it's a setting (usually in BIOS) that allows the CPU to access larger chunks of GPU VRAM at a time. It results in better frame rates in most situations - but worse frame rates in some cases. 

Do not disable ReBar. If it's working incorrectly, it's probably due to some other stuff. MSFS and MSFS2024 support it and there's no benefit at all to disable it - Actually the exact opposite.

This is specially true for nVidia cards and i would point it to a bad driver version more than an actual issue with the hardware.

Some older or poorly optimized games may experience lower performance or instability with Resizable BAR enabled. They were not designed with this feature in mind, and the broader memory access might not be handled well. Also, if you're CPU-limited, Resizable BAR might not help and could even cause minor stutters in certain games due to additional overhead or scheduling issues.

All the other cases benefit.

More magic potions and tricks that introduce more issues

Do some reading, it is as of now a fact that with rBar disabled in the BIOS, you easily get 2GB VRAM back, at least in my case. But as you said, it should not be like this and should be fixed by Asobo. Personally, I see slightly more stutters when having it off, still not sure if it is worth the 2GB VRAM usage though.

Exactly what I was thinking.

That's exactly what i did, some reading. I don't need any VRAM back because i have 16GB and i don't just dial up all the settings to the maximum, i only bring up what needs to be up and bring down what can be down because you don't notice it at all. Having said that and since i don't have any problems with MSFS before and MSFS2024 now even though i lost performance from the transaction, i find no way to blame ReBAR for any issues in the simulators.

I've had ReBAR enabled since it appeared, i have over 320 days of MSFS use (by its stats) and some more now in 2024, i play some games outside the simulators and i still have to find any issues coming from that.

I did have stutters in one occasion back when MSFS was in its earliest days and i had a 5900X, i had to use an AffinityMask to disable 6 of its cores to solve the issue.

These are just my experiences, i hope you get it sorted.

You made my day Nuno ! This means I am more than good with "just" a 5600x 🙂 with it's 6 cores / 12 if SMT... right? ANd indeed I did get worst performance when I enabled SMT... Reverted back to "normal mode" 🙂 and the 6 cores do their job very well ...
