I have uninstalled MSFS, removed all content under Packages, reinstalled MSFS as a clean install with no addons.
Are you using Developer Mode or made changes in it?
Brief description of the issue:
MSFS is drawing 100% load on the GPU (even in main menu). After starting a flight the GPU drops from 100% to 0% (causing a stutter) and goes back up to 100% for another 30 seconds. This behavior persists consistently and always 30 seconds between each stutter.
Provide Screenshot(s)/video(s) of the issue encountered:
Detail steps to reproduce the issue encountered:
Start a flight.
Wait 30 seconds.
PC specs for those who want to assist (if not entered in your profile)
CPU: i7 6800K 3.40GHz
GPU: 2 x GTX 1080 SLI (though issue persists even when running each GPU individually)

Yes. Ticket # 94764
— Regardless of graphic settings (tried Low-End and Ultra, and same result)
— Regardless of online setting (tried rolling cache on/off, deleted cache, tried manual cache on/off, tried connectivity turned completely off)
— Regardless of GPU configurations - Tried each GPU individually and in SLI and same behavior.
— Regardless of Refresh rate, VSYNC and Frame limiter - tried VSYNC and frame cap at 20, 30 and 60, as well as no frame limiter. Also tried setting monitor from 144Hz to 60Hz to match VSYNC 60fps. No difference.
— Regardless of which monitor game runs on - Tried changing it to windowed mode, shrank the window to smallest possible size and moved to second monitor. Stuttering persisted every 30 seconds, although GPU load went down to 45% and temperature was at 65°C which eliminates this being temperature throttling in the GPU.
— Tried turning off anti-virus, anti-malware and adding .exe file for flightsim to firewall exceptions list - no difference.
— Have been running other games at similar GPU loads and no other game has this behavior of dropping load to 0% every 30 seconds. This issue is exclusive to MSFS.
— Issue started happening early this week (spent 2-3 days now trying to troubleshoot the issue to no avail.
— Been playing MSFS for 600 hours since launch and not had any issues until now.
— PC hardware has been unchanged since 2017 with no issues like this in the past.
