I've noticed Sundays will often have a slight downgrade in my total performance, usually manifesting as a few stutters that would otherwise not be there.  Today at IniB KPSP TLOD appeared to be dropped down to 50 or less with blurrier close by mountains which are usually nice and crisp.  Same same for the taxiway line which out so many feet became blurrier whereas normally super crisp all the way out.  No stuttering at all, but makes me wonder if MS/A uses an algorithm when there is high demand to lower TLOD.  I noticed the main thread on my CPU was showing only about 30% utilization.  No change to TLOD settings impacted this as I was set at 200 and making changes in settings to TLOD made no difference.  

This begs a question:  would installing an airport, versus streaming, have any impact on this?

One question, Noel: your KPSP is installed or streamed? I'd understand if this was streamed.

There is something very wrong with KPSP since SU4 for me. The mountains morph in and out of sync with the terrain and there are strips of mismatching areas. I also have IniBuilds KPSP and though it might be the issue as I think I bought it just before SU4 came out. But installed, uninstalled, streamed or otherwise, makes no difference. I was hoping it would be addressed when I saw the California update but unfortunately not.

I am seeing this same problem all around the San Diego area of the California City update (and that is with SamScene city scenery disabled).

Streamed and too bad I didn't think of that then I could have installed then reran the scenario.  To be clear that was the only time of many uses of that airport that this issue appeared.  Haven't tried it since the Cali update.

I don't doubt this one bit. You are not truly in control of your game settings when you rely on streaming.

What's your TLOD?  I haven't noticed but I also have been running 600 via autofps (and have the vram issues to prove it lol)

Maybe your network was having a bad day. Have you tried installing the scenery?

I did yesterday and no difference so I changed back to streaming.  I've been there several times since SU4 and no problems until the other day...and yesterday.

I've been reading through the threads on the official forums and a few people have been complaining about stuttering over the last week or so, so you're probably correct.

I wonder if this is secondary to growing demand on servers which could be the case as more people are moving to 2024 now, since SU4 arrived.  The last 24h peak users in 2024 on Steamdb well exceeded 2020 peak users.  So...we give MS a little time to adjust....

TBH, till today i have no clue how things works in this sim 🙂

One day its good another day its worse

To be honest I fly in 2024 and 2020 before it nearly every day now for going on six years.  The number of times there has been any kind of significant issue with access or even performance has been so trivial it borders on irrelevant especially when considering how complex the entire process is, its cloud-dependency, and when considering the myriad of 3rd party content involved for most of us.

My TLOD is around 250, BUT when I experienced this it was at low level (around 1000') while flying a helicopter. My VRAM was nowhere near maxxed out. The scenery issues were happening on terrain right in front of me, maybe 500 feet.
