This is very annoying problem.
I have installed Microsoft Flight Simulator (MFS) 2020 on my PC:
i7 6700 (stock cooler, stock clock), 1660 Super (stock clock, dual fan), 16 GB RAM, 512GB SSD Samsung 850 Pro (Windows 10 20H2 19042.746 + Store version MFS 2020 install location).
On MFS2020, I frequently experienced CTD without any error messages. I couldn’t even finishing short 20 mins+ distance flight (takeoff, cruising, landing). I have played this game since December 2020 (since the 1.12.13.0 version) using M+KB+Xbox One Controller.
The game is set on mix low-medium-high graphic options and I limit the game to 30fps via Nvidia Control Panel. I turned off AI and live traffic, and other online functionality except Photogrammetry.
I have tried some hints and guidance here to minimizing CTD but none of them works. At some point I think this is must be software issues.
CTD feels like the game has been accidentally being pressed Alt+F4, just close. Until now, I have not found consistent error (like what exact duration/time or what I am doing when CTD).
Sometimes, CTD happens while I’m just leaving MFS 2020 running idle at world map flight plan menu for couple minutes (I think it may not using so much resources at menu).
But yesterday I made observations and give me little clue at least for my CTD case.
I checked CPU and other resources usage and temperature while playing this game and fly in some same rural area with not crowded city.
Using Xbox game bar and HWinfo, I see usage:
CPU: 40%-74% (100% spike at some point)
GPU: 48%-58%
VRAM: 75%
RAM: 70%
FPS: 30
CPU temp max: 62C
GPU temp max: 72C
At some point, in the middle of the flight, I heard the fan getting louder and when I checked again via XGB, I saw the CPU usage going from 40% to 100% top and there was some of 90%-100% CPU spike for few seconds, every few seconds.
Like from CPU 40%-70%, then up to 100% for few seconds and down to 40%, for few seconds and up again to 100% and so on.
I think this is happened because the CPU is working hard processing something/drawing the area. So I press paused, but the 100% spike still happened.
IIRC, paused the game worked for some games to decrease CPU/GPU usage for a moment (because it just draw menu interface). But this isn’t work for MFS 2020.
At that time, I thought it might be CTD soon because my CPU was choking. And right, a moment later CTD happened, desktop shown, MFS 2020 icon disappear from taskbar but it can still play sound (engine sounds) for a moment, and then stop.
I think CTD in my case happened after my CPU experiencing multiple 90%-100% spikes in certain time.
I am curious what makes the ‘spike’.
I tried multiple flight in same rural area after CTD.
I tried takeoff - flight - cruising - exit to main menu - load flight plan again - take off again - flight -and so on.
Sometimes the spike (and CTD) happened even in the first flight, and sometimes happened in second or third flight.
Sorry for the wordy post. but that’s my observation.
