I uninstalled it and also the Brisbane landmarks package… everything runs perfectly now.
They just cannot or won’t fix these issues. the latest update just made it worse, from slow to unplayable.
Orbx YBBN works absolutely fine for me. I actually flew there from Canberra yesterday.
I’m glad for you. Has never worked for me though, really bad fps issues, I asked on the forums (with lots of others with the exact same problems) and was advised to just “lower my graphics settings” - why would I do that when all other 3rd party airports work fine? I was really hoping the YBBN update I just installed would address the issues, but it actually made it worse. I have other ORBX products (actually lots of them) for X-Plane and MSFS that work fine and I’m happy with. but not this one. There is something fundamentally wrong with it that affects a lot of users, but maybe not all. Anyway, I can fly out of YBBN now and I’ll leave it at that. If anyone knows of any YBBN freeware, please let me know? Thanks.

The poor performance is most likely the result of VRAM exhaustion. If your graphics card has only 8gb of VRAM, you’ll need to set MSFS’s texture resolution setting to medium and the restart the sim. I struggled with these two addons until I realized what was causing the poor performance. Lowering the texture resolution helps to keep your VRAM usage within limit.
Thanks … My specs are Intel I-9 9900K / 32gb ram / RTX 3080Ti / SSD hard drive etc. That should be more than enough to handle YBBN. I really think there’s an underlying issue that has not come to light yet.
I recently built a new rig for MSFS that now has an RTX 3090 with 24GB of VRAM. I’ve tested my rig flying through Brisbane with both Orbx scenery packs installed. With texture resolution set to Ultra, i see VRAM usage >20GB in VR with an HP G2. A 3080ti has only 12GB VRAM. Sadly, the VRAM of a 3080ti is not enough for this combo. Lowering the texture resolution setting will help to keep VRAM usage in check. My old rig had a 2070S that i later replaced with a 3070FE. Both had 8GB of VRAM. I needed to set texture resolution to medium to keep this scenery combo within limit. If i recalll correctly, medium texture resolution used about 7GB VRAM and produced acceptable performance.

I do appreciate the technical advice, thank you. I spent an hour today testing, changing graphics settings, uninstalling, re installing YBBN etc… So I’m done for now. If and when I decide to revisit YBBN, I will try your solution.
It seems crazy that a $1200 video card cannot successfully run just this one airport. Oh well.
I agree 100% with you. Like you and quite a few others, I noticed the precise same issues pertaining to Orbx YBBN and Brisbane cityscape.
From my experience (and I’ll stay relevant to airport scenery in Aus) YSSY from Fly Tampa is a way superior scenery package in both looks and optimisations in comparison to Orbx YBBN. The resolution is Orbx need to rework YBBN and optimise the textures of the entire airport (just to begin with). That would definitely improve frames/smoothness/looks by a large margin. When a developer insists that consumers need to lower their settings to accommodate their scenery…in my experience, that indicates poorly developed scenery and I’ve been flight simming since the early 90’s and have pretty much seen it all.
I still fly in/out of YBBN from time to time, but had to uninstall Bris cityscape as it was further exacerbating my frames/smoothness into single digits/stuttering.
does anyone know what the YBBN upgrade included? is there a change log somewhere? I can’t find one…I was hoping they’d fix the non-connecting aerobridges as well as the look of them.
I saw something about the upgrade, you can search and probably find it, but in the list I don’t remember seeing anything about performance enhancements or optimization.
I’ve flown in there several times (inc yesterday) and had no performance issues, but I did d/l the latest NVidia driver and I suspect that’s given me CTD’s. I’m just disappointed BNE’s not up to quality level and MEL doesn’t exist - two major airports crying out for attention…
Ask any two people on YBBN performance and you’ll get two different answers! And that’s the whole problem.

I did a quick test to collect some data regarding VRAM usage. I’d like to share my results in hopes that it will help others.
i9-12900K, RTX 3090 with 24GB VRAM, 64GB DDR5, 1TB M2.NVMe, GR 522.25 driver, Win11 22H2, DX12
I started with MSFS’s 2D graphics render quality preset to Ultra, which sets all settings, including Texture Resolution, to Ultra. Monitor is 4K at 3840 x 2160. TAA 100, FSR 100. TLOD 200. I then changed only the Texture Resolution setting and restarted MSFS before each test.
I’ve both the Obrx YBBN airport and Brisbane City Pack installed. I chose the GorFriends Optica with departure from runway 19L. Preset time of 11:30 AM and preset weather of Few Clouds. I then recorded VRAM usage at time of spawning into the flight and then watched VRAM usage as I took off and flew directly to Brisban city center. I flew one loop around the city at low atlitude and returned to YBBN.
VRAM usage:
Ultra - 14.5GB on runway, 15.8GB over city center
HIgh - 11.5GB on runway, 13.8GB over city center
Medium - 9.7GB on runway, 10.1GB over city center
As one can see, the Texture Resolution setting has a sizable impact on VRAM usage. Once VRAM is exhausted, you’ll start to see FPS drop and / or a “pulsing” stutter effect.
I’ll also point out that I’m using DX12, which eats up more VRAM than DX11. I’d expect the VRAM usage for these tests to be a bit lower if / when using DX11.
In summary, those struggling with poor performance should take a closer look at VRAM usage. If your GPU’s VRAM is exhausted, try lowering the texture resolution setting until you find a happy place. You can then fiddle with TLOD setting to further fine tune VRAM usage.
Personally, I can’t see an appreciable visual difference between the Ultra, High, and Medium Texture Resolution Settings. But I sure did see the peformance degredation that VRAM exhaustion creates when I was using an RTX 2070 and 3070, both with only 8GB of VRAM.
You’ve got nothing to loose in trying a lower texture resolution setting other than a few minutes waiting for MSFS to restart.

I do appreciate all the testing and results you’ve shown… thank you!
I am testing right now, Tex Res set to HIGH does allow me to fly the airport albeit with a very slight stutter here and there, but not bad. Tex Res at MEDIUM worked well but I could really see a degradation in quality.
I’ll test the whole rig at HIGH and see how it looks at all the other places I fly and get back.
Again many thanks for your efforts!
Well, sadly after trying different planes and flights on and around YBBN the only way I can get smoothness is by reducing my Tex Res to MEDIUM OR LOW. And I can see the difference this makes. So considering all my other 3rd party airports seem to work fine at ULTRA, I’m ditching Orbx YBBN and Brisbane Landmarks.
It is very strange how some have no issues and others really do with this airport. Perhaps they will hear the complaints of many and really dig into it to fix it. We will see I guess.
thanks for all the input, I do appreciate it.
I understand your frustration, my friend.
Honestly, I think the problem with 3rd party development is that we, the consumer, put too high an emphasis on “high resolution” PBR textures. Forum pundants and YouTube infuencers fawn over high resolution textures and besmirch developers that don’t deliver expected eye candy. Accordingly, third party developers provide products with 4K or 8K (yikes!) textures to satisfy demand.
To what end? Sadly, poor performance.
MSFS’s default content, e.g. aircraft, airports, POIs, etc., are created with 2K textures. No one complains about the quality of default planes and scenery. I figure 2K textures are probably good enough as-is, but unfortunately most third party products contain higher resoltution textures to satisfy marketing needs. It is my belief that this lack of consistency in texture resolution between default and third party add-ons is what creates scenarios that harm performance.
These high resolution textures are what, I believe, are killing performance through VRAM exhaustion.
Good points, sounds right to me. But you would think Orbx would have some quality control that would not let one like this slip through. Most of their products, at least for me, work fine. Just not this particular one!

I think to improve the performance of the airport from this thread is to move some airports from Community folder temporarily to another folder we create as backup.
