Yes, it is nothing to do with the GPU, It affects the CPU.

You don't want to edict a rigid rule.

In my experience,it really depends on where and what you fly.  I have just flown in rural France - from Mende to Langogne which is a nice grass strip overlooking the river Allier - with the Cabri at LOD 400 without stutter. I obviously couldn't do that landing in Heathrow with a more complex aircraft

 Adapt your LOD to your flying environment is the true rule, IMHO

Thanks for the info...

That's disappointing to hear. I thought that the frame generation was supposed to help with CPU bound situations.

I am currently at 30fps and smooth with a 3090. I was going to upgrade to a 4090 to be able to run 60fps locked and smooth, but my only other requirement was to able to run LOD at 400.

You saved me from some real disappointment had I upgraded and still could not run LOD 400 without stutters

You probably could LOD 400 and be smooth, depends on the situation really. Not all scenarios are the same. 
 

Ps the 4090 is a well worthy upgrade to the 3090 should you decide to.

Out of interest, why do you want LOD 400? I’m running 4K and see barely noticeable difference between 200 and 400.

For where I fly, LOD 400 makes a noticeable difference + I would I pretty much be maxed out at everything MSFS with this last setting, and running 60fps locked, which is my goal.

I am conflicted, another 1500 USD to not quite get me there makes me want to wait. 30fps is doable for now, but 60fps would be much better for my Trackir. I may hold off until the summer and see where things are with MSFS performance etc.

I can just about manage Terrain LOD at 350 with a 4090/5800X3D.  I might get the occasional stutter on the ground in the Fenix at iniBuilds EGLL with FSLTL injecting but that seems to be its biggest test.  TLOD seems to make a noticeable difference in the blurriness of ground textures so it is something I like to max out as much as possible.  

I also use DLSDR @ 2.25x DL with DLSS which seems to be the key in getting it getting it run at 350.  Seems much more efficient than increasing render scaling and using TAA.

Your best bet would be to wait for the new 7XXX3D chips as well.  If anything is going to be able to max out TLOD reliably it will be these.  Also, given the sim will likely remain CPU limited, frame generation will further help here.  So if I upgraded to the 7800X3D and it gave me a 20% improvement in base performance, the increase in fps would be even more when paired with a 4090 and frame generation.  It's a strange dynamic, where a CPU upgrade could potentially yield such an uplift in frames per second despite not actually being responsible for half of them.

Frame generation sorts that, I rarely ever dip below 60fps, and most times I am at 100+ FPS...

I wondered about how FG deals with main thread overload....according to one of or the most committed proponent of always having the latest hardware--it doesn't.  Thought so...

This is so true.  Yes, there is a difference, but it's subtle especially if you're focused on flying/piloting you will be hard pressed to notice a difference and yet the impact on the main thread is huge relative to what you get for it.  This is why I have no interest in upgrading a system capable of producing a fabulous subjective experience in what amounts to yesterday's hardware. I will eventually upgrade but only when this box can't produce the excellent result it does now:  no stutters, ultra smooth animation and that is in and out of any airport anywhere in the PMDG 738, FBW A320NX and AS CRJ7.

Why would you expect a system that's CPU bound to become less so when your GPU runs more efficiently? 🤔

I didn't, that's why I said, "Thought so"...  The rhetoric point was that FG doesn't solve this problem.  Fortunately as Ian mentions--it just hardly matters, the thing you bought the new CPU for, to cope with Terrain LOD which hardly matters.

Matters to me! 400 TLOD, 4K, locked at 60... heaven! 😊

So...

The latest "best" LOD settings for SU11 is 200 / 200 when checking best graphics settings on the flight simulator blog. Seems to be quite high (espec. for object LOD).

Any suggestions?

Object LOD has next to no effect. And "high" depends on your hardware. It's fine for my average computer.

Good odour, even if you can hardly notice the difference--in fact, in a double-blinded test I'd bet against you doing much better than 50:50 if you didn't know where TLOD was set.  I've looked certainly seen it and flown 100's of hours at TLOD 400 in lesser planes and airports, and it's paltry, relative to the $4K you spent on your hardware, or whatever it was.  Glad you're happy, and glad I'm happy that I have no need for it.

Absolutely.
