I’ve got a rig that’s ready to soar through the skies with Microsoft Flight Simulator, or so I thought. My PC specs should be more than enough to guarantee a stellar flying experience, but here I am, wrestling with performance issues that have turned my flights into turbulence-filled nightmares.
My problem is not about low FPS, it is more like I get high drops/ high peeks if I take a look at the FPS counter of the MSFS developer mode.
I have no stutter while flying but when it comes to panning around with the camera, switching views, or moving with the arrow keys around the flight deck.
Remember the days of FSX, where we spent more time tweaking settings than actually taking to the virtual skies? Well, it’s like déjà vu. I’ve become a settings explorer again, hunting for the elusive ‘perfect’ configuration
Check out my setup:
AMD Ryzen 7 5800X3D
MSI Suprim X 3080TI 12 GB (latest driver)
be quiet! 850W power supply
G.Skill DDR4-3600 32GB
1000GB Gaming M.2
Windows 10 64bit
Nothing of my Hardware is overclocked. Everything runs with default speed and settings!
Just so you know, I’ve flipped off the Windows Game Mode, and hardware acceleration it’s off too.
I’m reaching out to this community in the hopes that together, we can bring Microsoft Flight Simulator back to its true glory on my setup. Let’s share insights, tips, and maybe unlock the secrets to taming this wild ride of performance issues.
Your HW is not the problem. I had a 3080Ti and you can run game with all maxed and TLOD 200 + OLOD 200 as well. The important setting to reduce to high are texture resolutions as card has only 10 GB usable for game from those 12GB.
I have the same stuttering and freezes like you with a 4090 and many users have them too, even with high-end systems. It´s a problem of AAU2 game version. Latest beta has included some memory optimizations but those issues are still present according to beta users.
I had to turn v sync on to eliminate those stutters. Your system blows mine out of the water .im running ultra woth a 9700k and a 3060ti amd couldnt be happier.
I already game you my opinion as ex-user of the same card. You can run game with Ultra, TLOD 200 (more is too much) and just reducing Textures to High. Main thread limitation is a general issue. The way to solve it is to reduce TLOD below 150 but due to current LODs quality you get a lot of polygonal objects even at medium distances, so I would keep it at 200. On very dense areas no matter the system you have you will be main thread limited anyway. That´s a limitation of current implementation. On the other hand that GPU can handle max quality, except with Ultra textures as VRAM grows like crazy (that´s why you need to stay on High). Unless you pretend to go 4K with additional scaling the card can handle your workload at your resolution without problems. I was running game at 3840x1600 with 125% scaling and I started to be GPU limited there, so that´s why I decided to switch to the 4090 that has more VRAM as well as additional computing power.
Have you cleared you Windows Shader cache? Ideally do this every time you change the gpu driver. Also it might help to delete and recreate the in sim rolling cache, but try the shader cache first.
Enable G-SYNC compatibility in NVCP
Enable G-SYNC in monitor - set monitor refresh to max.
Match monitor refresh in NVCP
Max Frame Rate is OFF in NVCP
V-SYNC ON in sim, set to whatever % you want.
For me it’s:
Monitor Refresh = 165Hz, G-SYNC compatibility = ON
NVCP Refresh = 165Hz
Max Frame Rate = OFF (I limit Max Frame Rate to 90 Hz in Riva Statistics Tuner.)
V-SYNC ON in sim @ 50% Monitor Refresh
That gives me a steady 82.5 FPS and 12 ms latency in a low overhead flight (Bonanza over the Sahara in clear skies.)
5800X3D
3090 Ti
I might play around with turning V-SYNC OFF, and using RSS to limit the frame rate, since it has much more granular control than the sim. You can also use RSS to set the sync timing much more precisely.
That’s not high on my priority list, though.
