I could use some opinions: Long story short - I have been struggling for literally months trying to get the performance I think I should, with the hardware listed in my signature + a pimax crystal light.

Finally, the other night, in desparation, I decided to basically go back to a completely vanilla sim (but still in the beta). So I took everything, except for a couple of absolutely needed things, out of the Community folder and then tested some exact scenarios that were always causing me to get lots of stutters.

To my disbelief, without my addons, the performance was monumentally better, to the point that I was able to put the pimax render setting to 1.00 and in the sim, started using DLSS DLAA. Quantum leap in performance. With some help from AutoFPS and Dynam,ic Settings in the sim.

So, concluding that addons are my issue, I started to consider what airports I have been doing most of my flights from: KLAS, KJFK, KSFO. I then realized that in my system, all three airports are represented by third party addons (Flightbeam KSFO, Glideslope KLAS, and Inibuilds KJFK).

This thread is not intended to critique any addons or discuss what's good or bad about any of them. I have one objective only: to get opinions on the performance impact on the MSFS 2024 system from the below listed items:

Flightbeam KSFO

Glideslope KLAS

Inibuilds KJFK

Samscene 3D Miami

Samscene 3D New York Times V2

Samscene 3D San Francisco

Lunapark Design Bay Area Bridges

 

PLEASE DO NOT HIJACK THIS THREAD BY GOING INTO ANYTHING REGARDING THESE ADDONS EXCEPT HOW THEY AFFECT PERFORMANCE IN THE MSFS 2024 SIM. THERE ARE PLENTY OF OTHER THREADS TO DISCUSS THE PROS OR CONS OF ANY ADDONS. THANK YOU.

Have you disabled the default asobo airports for  KJFK and KSFO?

I think so but I will check in the morning (it's 2am here LOL).

Certainly addon scenery can affect performance particularly where you have several airports close together.  Your system is good enough to use most of them though.  All of the ones you mention are quite heavy on VRAM usage, but your 4090 should have plenty for that.

I hit my 16 gb VRAM limit on a few if I don't turn my settings down a little.  TLOD, OLPD and texture quality being the most limiting.  Samscene new York v2 is particularly hard hitting for me, though v1 was never an issue.

I have found Samscene stuff especially hard hitting, particularly the newer more recently updated ones compared to the earlier versions.

Generally the worst for me is third party freeware photo scenery.  The larger cities, of course being the worst - some of the designers sem to optimise them better than others though.

Limiting framerates, using autoFPS (or similar) and/or just turning the main liiting settings down a little is usually the best solution if you want to use some of the above.
