Bought the game at launch and while performance was hit or miss in certain areas, I was able to get 60+ and well over 100+ fps at high altitudes. Now, I get around 35-45 at every airport and can barely touch above 50 fps at higher altitudes. I have noticed that my CPU and GPU usage is extremely low.
Notes: Hardware has been unchanged, only software change would be updated windows and gpu drivers. Temps are also more than fine.
What have I tried to fix:
Reinstalled Windows
Reinstalled GPU Drivers
MOBO Bios update
reinstalling the game entirely 3 times
No Addons
Low graphic options and turned off traffic
Xbox Game bar has been removed
Xbox Game Mode on/off
Full screen Optimizations on/off
Compatibility Mode on/off
XMP on/off
CPU Affinity and Priority Tweaks
Hardware
RTX 3090 EVGA ftw3 ultra
I7-9700k
32GB ram
Game is installed on samsung ssd
Gigabit ethernet
I noticed issues a week ago when I reinstalled the game for the first time since month of release.
Yea what the actual hell happened here. I stopped playing because I broke my yoke and decided to try the game because I was enjoying it at launch. Come back to similar, if not worse, looking visuals but a FRACTION of the fps.
We can only hope. I tried it yesterday and for me it is basically unplayable… Tried to land with the A320 on KMIA, and it actually turned into a slideshow. And it is the exact same behavior. On approach it is ok-ish, at about 30 FPS (used to get 40 when the sim launched). But at about 700ft AGL, the 3d objects in the airport disappear, respawn, and then performance goes down the toilet. From 30 to about 10-12 FPS, with actual pauses that you can measure (of about a second), stutters all over the place, GPU utilization of around 40%, and limited by main thread. I foolishly updated my CPU (from a Ryzen 5 3600 to a 5600X), thinking that would help, but it is basically the same, so I spend money on a CPU that I didn´t really needed (don´t get me wrong, it is a great CPU, and no update is “useless”, but it appears that it was not needed).
Half your luck getting at least 35+. My system I used to get 35-40+ fps but now when approach an airport and landing getting 15-20 fps. Getting unusable now. The performance is just garbage. At times can stutter and drop to like 5-10 fps. Now watching a slideshow.
I stubled upon this topic and post, and this has solved my “Limited by Main Thread” issue just like yours and able to get back to having stable FPS. Maybe this can help you as well.
