For some time now I have been having ever degrading performance.  Long and frequent stutters.  Every flight, regardless.  I thought it was GSX, uninstalled it, same issue.  Uninstalled Flow Pro, same issue.   Cleared out NVIDIA DX/DL folders, set NCP to default.  Same issue.  Looked through my settings and saw that Off Screen Terrain Pre-caching was set to high.  Changed it to Low and the severe stuttering stopped.  My rolling cache is always turned off.

What does everyone else use for this setting?

 

Ultra. Planning to increase my RAM from 16Gb to 32Gb in a near future.

No performance issues?

Ultra is the setting to use in order to avoid stuttering when panning the view.

I am surprised that low works best for you, what CPU do you have?

Of course I do have stutters now and then. Especially on larger and more complicated airports. Hoping that increasing the memory would smooth out things a little bit.

Maybe a little bit. Stutters have plagued sims for decades. The only sim I’ve ever seen 100% stutter free was when X-Plane went to vulkan. 
Even on high end hardware, expect some stutters every now and then, if you’re throwing things like AI and extra airfield etc at it, It’s the nature of the beast. 
Plus the MSFS engine could handle it better (bring on 2024!).

Still at a loss here, because according to responses, a high setting for OSTPC should not be causing the issues I was experiencing (Long, frequent stutters when panning).  So am now wondering whether the performance improvement was something else I may have changed.  Will have to do some more assessment this evening.

The misunderstanding is that the higher the OSTPC setting is, the less it will stutter when panning. This setting was introduced after SU5 destroyed the LOD (and other things) to make the sim fit into the small memory of the XBox. Basically "low" makes it keep in the VRAM only the scenery in front of the POV!

On my old 10850K, Ultra = no stuttering at all, Low = stuttering when panning. 

Considering your CPU, try OSTPC Ultra and Terrain LOD 100.

Anyone knows if pre caching has only influence on calculating the view circle horizontally or also vertically?  So when banking ….

I'm always on ULTRA and have no issues I have noticed.

Having tested this setting it is quite clear that the higher the setting, the lower my FPS is.  However, the higher settings also reduce or remove stuttering when panning.

I found either medium or even low best for me for a long time but having recently got TrackIR I obviously am panning a lot more and have increased setting to high. Ultra is better of course if your system can take it but most of us have to make a compromise or two.

I've found stuttering when panning (TrackIR) to be unbearable using anything other than Ultra OSTPC. As can be seen from my specs Ultra can work best even on humble systems.

Having done more tests last night, my issue is not OSTPC.  As most here have said, Ultra setting does actually provide the best.  My initial tests were not true.

I think my issue is to do with G-SYNC/VSYNC.  There's a new thread about it and I have to play around with my settings.  

Moved from XP12 to MSFS a week ago, I got horrible stuttering close to a small airport (LFMT) in VR mode only.

In VR, this stuttering looks so strange to me for this kind of small airport like LFMT; while flight around the town (which is already 3D with a lot of Google Earth objects) was really really smooth in VR without any lag.

Since several days, I tried several setups (removed G-SYNC, rolling cache = OFF, LOD, resolution) but got almost the same stuttering.

I thought it was due my quest Pro Headset limitation (stream compression / decompression) and was considering send it back...

But by chance yesterday, I decided to change texture resolution to LOW and OFF Screen Terrain Pre-caching OSTPC to LOW -> stuttering is gone !

I will check again going back to OSTPC = HIGH if stuttering is back
