This may be an explanation: bad multicore usage... I don't remember it being like this in CPU limited scenarios, it is almost single thread now!

This looks good. Your main thread core will always be at high load, while others have a much lower load...

 

I've taken a break from MSFS after too many unpredictable stutters and pauses recently. The event that really made me loose motivation was a CTD on approach into Florence after an otherwise enjoyable flight. 

I fly with AI traffic (ground and air) off but multiplayer on. Also rolling cache on, dunno if that causes performance degradation...

Mine exhibits similar behaviour, CPU is literally asleep and GPU is being taxed to the max. I get as low as 20fps in some places and 60fps in some others and doesn't even need to be pointing at the sky or with no land at all, it just depends on location somehow.

As already mentioned, I observe much more stutters, even in remote areas with small aircraft. I have no live traffic but ai generated traffic. It is very random and not necessarily dependent on add-ons. I have bad stutters in Upper Austria flying towards the Alpes with no mesh or airport addons being active. On the other hand I have smooth flights over Vancouver Island with 3rd party mesh and some add-on airports.

So I am wondering what will happen when DX12 is introduced ?  More load will be put on the graphics card, both GPU and VRAM. 
Not everyone has a 3090 with 24 Gb VRAM.

That is true. While i run on a laptop now due to space and mobility constraints (i need to take the PC with me quite often), there isn't really much difference from the 5800x / 2080Ti i left behind, if any. P3D runs so well nowadays, i hope they bring major improvements to MSFS with DX12 and moving tasks to other threads.

How far away is dx12 from being implemented?

I think they mentioned something like "still going to make it in 2021" IIRC.

Thanks Nuno

KATL-data Sim loading

I noticed some stuttering on airports after SU4. And I noticed quite a few CRJ aircraft on every airport I flew to. I checked them, and I guess they were Aerosoft CRJ models with full poly count. So if you have installed the CRJ or other 3rd party aircraft you might want to set "use generic aircraft for AI" (sorry, don't know the exact wording - but you'll find out for sure) in your settings. For me it resolved the issue - but I have to live with those ugly standard aircraft.

I'm CTD on short final at every airport after this update. Quite annoying.

Didn't some people wanted more trees? I have noticed more tress than before flyingl over SoCal today!

They wanted trees extended out further from the aircraft when in flight not more concentrated trees in an area.  By the very nature of Georgia and it's foliage Asobo may need a more friendly approach to texturing for these types of trees.  I actually noticed performance going down his after the USA Update was released and a detailed KATL was put in place by Asobo.  It was downhill from there.

AI traffic is the FPS killer for me. I think they upped the amount of it for a given setting  in the update. 

I had Live Traffic 'off' and still saw a problem on approach to runway 13 at KFFC.  I just recently tried AI Live Traffic so I know this was not a factor in what I've been seeing in the last few months only to get much worse after this update.

I have noticed that on a long final towards a large airport that nasty stutters (1 second or more pauses) occur as one descends below about 4000 feet agl. On a hunch, I went into the options/traffic page and turned EVERYTHING off: Live traffic, AI traffic, cars, boats, ground stuff at the airport (planes, vehicles, workers), everything. Next approach to same airport was a LOT smoother.

My guess is that these stutters are due to the sim loading assets (and in the case of moving assets, such as vehicles, putting them in motion) as one comes into range for them to be displayed.

I'd be interested if anyone else can try this and confirm my observation.
