Sudden FPS drop

Same here. Horrible stutters on final and when I went poking around I noticed that the rolling cache was turned on. Somehow it turned itself on. I turned it off and no more stutters.

I wasn't getting stutters, but after reading your post, I checked, and sure enough "rolling cache" ( which I have never used since day one) was turned on.

    Yes they can, but first you have to go to NV Control Panel and set Shader Cache Size to Disabled, then reboot and delete the files. Set Shader Cache Size back to what it was and reboot again.

  • I have terrible performance after SU15 for some reason I cant figure out. PG is on in my case.

  • Reproducible loss of FPS irrespective of location and sim session? If so, yikes! Let us know which one it was, please. That's too big a performance loss for very little upside.

I've always had the rolling cache on and never had these stutters. 

I'll try turning it off 🤞

If you wish to use it, it needs to at least be deleted and then turned back on after each sim update, otherwise you get major stutters.

Same here, experiencing stutter even flying in remote areas over the African bush with no cities or large airports around. Tried PG on and off and even went back to DX 11. Thought that was the solution but last night the stutters were back. I can get 60 fps without a problem on my system but even limiting it to 30 fps results in stutters with my GPU and CPU not even braking a sweat.

Unfortunately I have done this numerous times since the update with no luck. It's looking like a reinstall which I really don't want to have to do. 

Thanks for the tip anyway.

I'll give it a go after work.

Thank You.

After trying all of the suggestions in this thread, nothing helped. I ploughed through the fsuipc forum and saw a post where someone was having problems and saw there was a beta fsuipc linked which I downloaded and installed. 

I'm not saying this is the cure for everybody but in my testing scenario, performance seemed to be more stable for me maintaining steady fps but this was on the ground with everything loaded up. Im yet to do an actual flight but so far so good. Fingers crossed 🤞

Clearing all those cache files did the trick for me. It is now a pleasure flying again even over some PG areas. Will have to start a MSFS housekeeping schedule to manage this.🙂

Can you link to the beta version please?

Can you list which cache files you cleared....besides Rolling Chase ?  

I have noticed very annoying stutters on every approach lately....right around 1,000 AGL.  Really bothersome.  I will turn off Rolling cache and test.

I’ve just realised the DXCache folder from NVIDIA has moved. I found it and it was full!

AMD Ryzen™ 9 9900X3D, AM5, Zen 5, 12 Core, 24 Threads, 4.4GHz, 5.5GHz Turbo
64GB (2x32GB) DDR5 6000MHz Corsair Vengeance
32GB GeForce® RTX 5090 Graphics Card

I have had very few issues, if any, up until SU15. I now experience very jittery flying in heavy cloud scenarios. This never used to be an issue, especially when flying the A2A Comanche, which has always delivered exemplary performance, normally 50fps+ in normal flight, even in cloud. The other day it became very stuttery wth fps down to the early 30's, which in itself isn't a problem, as long as it's smooth. At first I thought it must have been a Windows update which had kicked in. I checked this, but nope, no Win update, then I remembered I have update turned off anyway! I've got very bored with the whole mandatory update thing with 2020, it's a complete and utter joke.  At least with P3d if I experienced any issue I could reinstall a backup, of course this is impossible with 2020.

I found another video by OverKillSimulations that is more aligned to what I found and there is a batch file available from the author that automates most of the process.
