LOD and popping

Sebastian Wloch just talked about this as a last point in the Q&A

 

It is a bug.

They did not deliberately change any drawing distance. They are actually working on increasing it further on upper levels, because it will come with an absolutely negligible performance and bandwith impact.

This is a slightly different issue, but also applicable to the LOD problem for those who fly at higher altitudes. Right now the sim transitions from high resolution textures and generated autogen buikdings to pure (lower resolution) satellite imagery at too low an altitude. Sebastian said that currently, if you fly an airliner at 30,000 feet you are certain to get only the lower resolution satellite imagery, which was not their original intention. This will be changed to keep the transition from happening until 90,000 feet.

Just to test I upped the LOD to 200 at Los Angeles, and the draw distance is absolutely phenomenal. It's a non issue.

It's a non-issue if your system can support LOD 200 without cramping the frame rate.

I get my best flyable frame rate of low 30's to 40 fps at LOD 100, both before and after the patch. If I boost LOD to 200, my frame rate drops to 30 fps or a little under, which is unacceptable (for me).  

What's odd is that I don't see any real improvement in trees popping in, or that weird blurry texture in the middle distance with the LOD slider at 25, 100, or 200, but the frame rate changes! It's like the CPU is crunching textures and objects but they're not making it through to the GPU. This is in areas away from photogrammetry, where it's not as noticeable for some reason.

If we're not seeing the same things, then it may be due to some difference in our systems, or just the areas we're flying.

I think it might be. Altitude seems to also play a factor, with there being a sweet bitter spot where the tree pop-in is very obvious, and least with some scenery.

Right, I notice the artifacts like pop-in and blurred middle distance the most when flying at around 1,500-2,000 feet when sightseeing. Maybe people who fly airliners and quickly reach the flight levels aren't noticing it as much.

I get 30+ with LOD setting 80 (sufficient for me) when flying the Airbus. LOD 200 gets me 30+ in the Cessna, in the Airbus, it drops below 30 in heavy areas. i4790K.

Some people on the official forums have found GEForce experience is automatically ‘optimizing’ graphics and downgrading detail / LOD.

Maybe adding to Asobo’s patch bug.

Interesting, but I just did a quick check on that, and it doesn't seem to be the problem.

I opened GeForce Experience and saw that it was "optimized" for MSFS, then clicked the "Revert" button that turns auto-optimization off. Booted up MSFS and checked my graphic sliders, no change from where I had set it before.  Object LOD still at 100.

Did a quick test flight with the Caravan out of my usual home area that has no photogrammetry, and saw the same trees popping in, much less autogen than before the patch, and blurred ground in the middle distance. Just to be sure, after closing the sim I launched GeForce Experience again, and the optimization setting was still off.

On my system at least, GeForce Experience isn't the problem.

The cause may have been discovered and it may be that tree LOD is tied to tree height. See the thread at https://forums.flightsimulator.com/t/lod-problems-trees-fix-revisited/296923/24

2 years later and I still am having this stupid issue.

Same here, so annoying
