I've been experiencing big stutters when on short final.  This has been happening at default airports into larger US cities like SFO, but also smaller cities like Columbus.  Is anyone else experiencing this and if so, what do you find is a cause and how do you fix it?  Taking off out of 3rd party airports and large cities is fine.  I am just experiencing this on approach.  For what it is worth, my specs are in my sig and I have been using the Google mod of late.  Here are a few of my settings that might be helpful

LOD - 160

Render Scale - 100

Vsync - off

Off Screen Terrain Pre cache (no idea what this does) - 100

Vector data - ultra

Objects level of detail - 100

Clouds - high

Texture res - ultra

Antistropic -16x

texture supersample - off

contact shadows - ultra

shadow maps - 1536

terrain shadows 1040

Probably  the Google Mod.

Is that a known issue?  I was hoping it wasn't the mod because the sim has looked better than ever for me

I read a couple of posts on the MS Group  Facebook page in the last few days , where they said it happened.

I have been more than happy with the Bing map data , I felt no need to screw up my great running Sim .

Probably not the google maps mod.

I used to see those stutters on approach. Noticed that at the same time, static and ai aircraft were being loaded and placed on the airport. It's worse if you have a lot of "large" (4k and 8k) liveries that can be used as static/ai planes at an airport. Since installing AIG with their AI optimized models and turning off all other liveries except the one I'm flying (Addon Linker is great for that) I have not seen much in the way of final approach stuttering.

Using Win10/SU6, my FPS drops from 60 FPS to 1 FPS after 30 minutes or so of flying. After about 30 seconds, it recovers back to 60 FPS.

Had the same problem, my framerate used to drop to 16 fps on short final (from 30-35 fps). Solved it by switching "Raymarched reflections" to OFF. Also try switching "Grass and bushes" to Medium, maybe the reason is - as you come closer to the ground those Grass and bushes starts hitting the GPU harder than when you are in the sky. Also try to reduce the amount of aircraft traffic and airport vehicles/workers etc. Hope that helps.

If it's not primarily the Google mod (how was it before you added that?), it's a blend of other potential sources unique to your hardware and unique configuration of the sim.  I used to get this regularly until I learned for me the most important variable is Terrain LOD--once I determined where it needs to be based on how complex the plane and route will be I've yet to have the sim stutter on final approach.  For me the range is 200 to 400, and in complex arrival airports like FT's KLAS, or KJFK, KSFO etc in the 787-10 HD typically 220 is fine but has needed to to go 200 on rare occasion.  On simpler airports and planes up to 400 works great--fortunately visually the difference isn't all that great.  My GPU can easily cope with Raymarched Reflections hence it really depends on all the variables involved.

Just a case of lowering your settings a little and then cranking them up one at a time until the stutters start again.

Unless it's hardare related of course, so update all of your drivers id this is the case - in respect of chipset drivers, it's best to download from the providers website rather than rely on Windows.

Funny you say this actually... I forgot to mention that this started right around when I started using AIG so that could be a culprit.  The weird thing for me though is that I only have static planes at gates currently when using AIG.  I can't figure out to get them to be non static if that makes sense.  I'll look to see if the models are optimized.  I haven't checked that.

What exactly are raymarched reflections?

I searched and found that it was discussed here

 

When you misread the post title...

Based on the settings I currently have below, what do you suggest I reduce? I changed some from the original post.  I get really bad pauses and stutters only on final.  Everything else is smooth

Vsync ON

FPS limit 60

LOD - 200

Render Scale - 100

Vsync - off

Off Screen Terrain Pre cache (no idea what this does) - Ultra

Vector data - ultra

Objects level of detail - 100

Building - high

trees - high

Clouds - high

Texture res - ultra

texture synth - ultra

Antistropic -16x

texture supersample - off

contact shadows - ultra

terrain shadows, contact shadows, windshield, ambient - high

shadow maps - 1536

terrain shadows 1040 

cubemap reflections - 64

Depth of field, bloom, motion blur, lens correction, lens flare, raymarch  - off

cockpit refresh - medium

There was a recent tip this week about turning Photogrammetry off. Have you tried this? That also helped me to eliminated those dreaded final short stutters.
