Even got REX weather force working again after they released an update. I find their newest version is the best so far. No abrupt changes in weather. No fps hit.

 

Well. Just had fps plummet with weather change. So it seems REX still has some issues.

I've found Terrain LOD to be, by far, the most important variable in terms of impact on the main thread.

That's what hits my FPS the hardest. I can run everything on Ultra, Render Scale at 200, etc. Soon as TLOD goes over 100 the FPS drop significantly.

I find that when flying high and fast in an airliner there’s not much point in cranking the TLOD up. Flying that fast either prevents the scenery from loading correctly or puts too much stress on the hardware. Flying solo in an airliner is usually quite busy anyway so not much chance of sightseeing. In addition I guess some airliners (like the FBW 320) can be quite resource demanding, putting even more stress on hardware which causes stutters, freezes - perhaps also the occasional CTD.

In some situations reducing TLOD to 100-120 is necessary to avoid a stutterfest, like on the ground, takeoff, final approach. Some addon airports are certainly more resource demanding /  poorly optimized than other (e.g. iniScene Heathrow).

Low and slow is very different as scenery has more time to download and render. Going up to TLOD 400 in these situations is usually ok for my system. In addition to most/all settings on ultra. Unless in/out from a major hub. I usually don’t depart from Heathrow in a 172 so that situation is usually not applicable.

I can agree with all of those points and would add for me the difference between TLOD 120 and 200, visually, is not that much.  I've also just learned photogrammetry OFF is not a bad thing visually and dis-iimpacts the mainthread, so higher TLOD can be accommodated.  The autogen is so vastly superior to P3D's it's still a giant plus.  I've never been clear on what is PG and what isn't.  I think PG will likely iimprove over time.
