Does anyone understand exactly what this setting does.  Obviously it increases and decreases the resolution of the sim textures, though high and ultra settings can have quite a performance hit.

However, my query is around whether the resolution you are using would make it worthwhile to use the higher settings.  i.e. Ultra may display very well in 4 K but are you just wasting resources using ultra when you are running the sim at 2 K.

My eyes seem to tell me that using 2 K the sim looks better in Ultra but are my eyes actually playing tricks on me or am I really seeing what I think I'm seeing?

For me it does look better in Ultra.. .not by alot but enough for me to leave it enabled and find other ways of managing my VRAM (It does have a hit on VRAM) You and i both operate at similar if not the exact same resolution so i don't think your seeing things. Its just a matter of tolerance and for me coming from msfs2020 where everything was pretty much sharp and detailed going from that to "high" texture resolution in msfs2024 was not doing it for me so i had to bump it back to ultra and find the VRAM savings elsewhere.

Yeah, sometimes better to turn down the TLOD and OLOD a little to keep the ultra textures on, though I use the in game dynamic settings to do that for me when needed.  

I'm running DLAA and 2X native FRG with a TLOD of 250 and OLOD of 200 which many probably think is a bit high, but it gives m the balance of visuals and performance I want and my framerate is sat at 60 most of the time, though the dynamic settings kick in automatically at 55 if I need them (which is quite rare).

Anyone else have any thoughts or views?

If I understand correctly, it doesn't set a max texture resolution but a level of downgrade, in which Ultra means no downgrade at all. It will depend on the base textures you have.

For comparison, FSX and P3D allowed you to set directly a max resolution. You could set max 1024px textures, 2048 px textures or even 4K. I liked that approach better.

Thanks Luis, So with texture resolution set to ultra running at 2K, if I have addon aircraft or scenery with 4K textures, the sim will try to render the 4K textures even though I am running at 2K - am I understanding you correctly.

I believe what Luis states is correct. However to me this isn't really an issue. The default sim textures for me needs to be at the highest quality for me to be happy and on top of that  Asobo cannot really go overboard with the resolutions considering they have to work with a ride range of devices and they have to be cognizant of the fact that the majority of people are not running 4090's/5090's to absorb the requisite increase in texture size. 

What i do is pretty much strictly monitor everything that is ADDED to the sim. For example  AI aircraft has to be 2k or less and the liveries for the addons i use must be at max 4k. I will not use anything made in 8k no matter how "good" it looks.
