Noel, I believe the default tree draw distance extension means you can lower your terrain LOD setting to get the look you prefer and maintain the performance level you want. With the improvements made, a setting of 4.0 (400 with the slider) is giving me the look I prefer that took a setting of 5.25 in the Usercfg file to achieve pre SU6. Some experimentation is probably in order to find the new balance you want between visuals and performance (fps) for your system. Of course, this is based on just a few test flights I do in several areas but from what I observed in my personal tests I believe this will be the case. 

It's been fundmentally changed, exactly what that variable actually does I'm guessing, else we would not see the big jump in VRAM use at equivalent values.  Even at LOD 300 via the slider for terrain VRAM is still well above what it was previously, so perhaps 400 is really closer to 200 or 250 using the slider now.  Haven't really seen the benefits because my one flight was in heavy clouds the entire way so never saw the terrain in the distance.  But yes, this was comment above, " Of course, we have a slew of sliders to move around as needed, so this is not a bad thing it just it is what it is..."

Thank you.. I needed some justification to convince my wife why I spent my kid's school fees on a graphics card.. not sure if she would know or appreciate the concept of VRAM though.. 😆

Very hard to tell where it will shake out long term, but yes VRAM in use has gone up by about 20% for the moment, presumably with more detail to show for it, we sure hope.  

SU6 is making more use of the expensive hardware that I've invested in and I'm really happy with that. I knew that MSFS will eventually get around to letting users who invested in top of the line equipment will finally get use out of them with flexibility of dialing in the sweet spot with additional graphic settings and sliders. Especially PC version, since everyone has different hardware configurations.

Same for me. Performance is noticeably down, stutters introduced where there were none before. 

And it's not because of the Terrain LOD 400, I already had that in UserCfg.opt file. 

I suspect those who have locked frames at 30 doesn't notice it because their system was already capable of more. 

I don't believe LOD 400 done previously thru UserCfg.opt is at all the same as setting LOD to 400 in the slider.  I'm estimating a 20% increase in VRAM using the same 400 value as I used previously.  In fact, it may well be that 400 pre SU6 is around the same now as  200 post SU6.

The one flight I took, low level had it stuttering like mad. Pretty annoying! Never did this in SU5.

Have you cleared your rolling / static cache? Sim seems smoother here (on 4K @ Ultra) especially in areas with dense traffic and photogrammetry - Don't have frames locked but am running Gsync on a 120hz display; vsync disabled.

Glad to see some of the fixes - especially for me starting at Marketplace airports I had purchased - I can now seem to start at them.    However I am definitely getting more stutters - not a complete deal breaker (and one I figured was coming when Asobo was going to tweak the performance again) but it was nice to fly and not get one stutter the entire flight.

There is no question VRAM in use went way up compared to prior to SU6, in the air and on the ground.  My sense is the terrain detail slider is doing something very different from what editing the .opt file did, but not sure exactly how.  It's hard to guess where it will end up, but right now RTX 3090 users will be pleased they have the resources to grapple with that.  On my first flight in SU6, B787-10 HD, KIAD to KORD, in the air at FL400 I'm seeing over 9Gb in use, and landing at KORD made it all the way up to 11.96Gb (3080Ti), whereas prior to that this flight would have seen ~7.2Gb or less at FL400, and maybe 9.2Gb at KORD, and that is with the LOD-T at 400 via the .opt and now via the slider.  Of course, we have a slew of sliders to move around as needed, so this is not a bad thing it just it is what it is.  For me I felt distance detail quality was perfect pre SU6, so not yet sure what this increase in VRAM use really means quite yet.

I just did some testing at KJFK and flying around Manhattan in a very simple aircraft, the Carenado Cessna 170. Clear skies, no traffic.

VRAM climbed to around 11 GB
GPU usage decreased the more complex and stuttery the scenery became. Which is a reversal of what it should do. Before SU 6 my GPU would run at 100% and I got great FPS, now it's chilling at 75-95%, but when the most complex scenery over Manhattan arrived, GPU usage dropped to as low as 70%. 

I'm getting around 35 FPS on the ground at KJFK now, I used to get 45. In the air I used to get 65+, now I'm at 45. 

Meaning around 20-30% drop in performance.

I will try clearing it now. 

I'm getting 20-30% less performance than before SU6. GPU usage down 20-30% as well. I don't have frames locked either. G-Sync 90Hz, no V-Sync.

I think part of what we're seeing is the impact of some sliders is fundamentally different than it was pre SU6, such that if you have them all the same as pre SU6, you will need to change some, but in the end visually, once you've readjusted, may we be very close to identical.  For example, LOD-Terrain at 400 previously may well be close to what LOD-Terrain 200 is currently, or something along those line.  IOW, I don't think performance relative to processing power involved has changed much if any, but you may need to readjust some sliders to end up with the same visuals at a similar level of processing power requirement.

Best update so far for me. No complains !

Yes, at last VRAM started to work again with the latest update. I had also some increase on System memory. Made some tests around Paris, great fps , smooth performance with  LOD 350 at ultra settings.

I think what's changed is what sliders are doing.  IOW, you will need to dial back some sliders and in doing so will get the same visuals at a similar processing cost.  So if you leave all sliders the same as pre SU6, it will definitely appear that 'performance' has dropped, when in reality it may well be visuals have improved and there is a cost for that.  Or something along those lines...

Plus, they're still adjusting.  It may well be we will see this tweaked again in SU7, and SU8, etc.  In the mean time, adjust sliders to get the sim where you want it, and ignore the values involved just pay attention to the end result of visuals and animation quality.

LOD-Terrain at 400 previously may well be close to what LOD-Terrain 200 is currently

That is what I think also, Lod 200 looks great for me now.

You could be right about that, but there's something that has changed when it comes to GPU usage as well. 

Before this SU6 update my GPU would run at 100% even when in the menus (with hangar in background). Now its 60%. That's not bad in itself, it's an improvement. 
But I see the same thing in game. When flying. GPU usage significantly down. 🤔
