That might be your issue, maybe go back to the previous verision
I had the previous version, tried the version before that - no difference.
Show us your graphics settings above the DX11 setting thx.
Finally got a steady 30 FPS with the three monitors, 1 touchscreen on internal GPU and 1 screen on Spacedesk. So likely the best I am going to do!
Thanks all who responded - sometimes just the conversations here lead to success after hearing new ideas. Appreciate it!
What are your traffic settings like? AI traffic (especially third party stuff like FSLTL), ground vehicles, airport workers, ship traffic, etc. can also hammer the CPU. If you are still CPU/main thread limited like in your first screenshot, I would take a look at those settings.
30 still sounds pretty low, especially if it’s still true at lower loads (say in a simple GA plane at altitude).
Have you checked your CPU temperature and clock frequencies? I’d recommend running something like HWiNFO64 and a CPU stress test like Prime95. If it gets way too hot, it would throttle and become much slower than intended.
Could be poor contact between CPU and heatsink, for example.
There must be somthing wrong with the CPU. You should easily get 60 FPS with those Settings and that CPU.
Did you test other games? Do they run normal?
Maybe a BIOS Upgrade is needed for the X3D to work?
Something is indeed very, very wrong on a fundamental computer component level. OP’s system is superior to mine.
I have most settings on Ultra/High, and I get 80 FPS/ 12ms total latency in a GA plane flying over the Saudi desert @ 1500 AGL (desert and rocks.)
5800X3D on a 240mm closed-loop liquid cooler (around 55°C during flight)
RTX 3090 Ti (fans only, around 65°C during flight)
1440p (nVdia driver 536.67) Was running 536.23 - worked well, but wanted to test the newest driver. Stable so far.
DX11/ HDR on
Main monitor on DisplayPort: 1440p@165 Hz.
Extended desktop (touchscreen) on HDMI: 1080p@60 Hz
Riva Statistics Tuner frame cap 90.
Frame Sync on @ 50%
I have a TON of addons running, and my Community folder has a bunch of things in it as well.
OP, check your motherboard BIOS and update if needed. Then install chipset drivers.
After installing HWinfo64 please report back. Check your CPU stats (temp, frequency, load.)
Also, install Riva Statistics Tuner (configure and set to run on Windows login) and install CapFrameX
Run CapFrameX with the sim running.
Here’s a CapFrameX three minute capture I just did.
Turn off Vsync - apply and save.
New PC… is your full RAM speed turned on in the BIOS settings?
Before I built my new computer, I was running three 27 inch monitors. The main monitor was set for 2k, the side monitors were set for 1080p. I was getting around 26 fps at the Atlanta airport KATL in the PMDG 737-700. After take off it would get up into the high 30’s. My specs were an I9 10900k with a 2080ti and m.2 ssd’s. It took some time tweaking settings in the sim’s graphic menu. Some were set at high, a few at ultra and the rest at medium. LOD was set around 100. That was with a reasonable amount of airport traffic. At small airports in the C-152, I could get upwards of 35 on the ground and 40’s in the air. Setting the side monitors at 1080 was good for 3 or 4 more FPS and didn’t seem to degrade the scenery much while looking out the side windows. I just built a new system with an I9 13th gen, 4090. I put the side monitors at 2k. I get a solid 30 FPS at the Atlanta airport with most of the settings set at high in the 737 with traffic turned on. I get into the 40’s and 50’s while cruising at altitude.
Well I’m tapped out - everything on my end is correct and triple checked.
CanI ask what other settings you have your system at running three 2K monitors? Thanks!
This is with my new system. Three 27" monitors all set to 2k. I9 13900k, msi 4090, m.2 ssd’s, corsair 360 cooler. Two sticks of 32 memory, xmp turned for 6000 mhz. I’m sitting at the Atlanta airport now inside the pmdg 737-700 cold and dark. As a baseline I have weather turned off, traffic turned off.
GPU is at 2775 mhz temp 55 degrees, CPU 5586 mhz temp 56.
FPS is hovering around 44

Did you perform a fresh install of Windows with your upgrade?
Couple of things. Vsync takes the load off the GPU, and Reflex Mode requires that you be GPU bound. Since you are at 44fps, your monitor is likely 60hz or higher, and with Monitor refresh at 100, vsync is not really doing anything. Best to set it so your FPS is 30fps, and turn up the graphic settings. To ensure you are GPU bound you may try Renderscaling at 120%, but it varies by system. 120 is the sweet spot with my 4k monitor, and you can find your own best setting. Also, Reflex works best with DX12. For DX11 use Low Latency Mode=Ultra in the Nvidia control panel.
So, turn off Vsync and go with Reflex Mode and DX12 and GPU bound would be my recommendation.
Did you ever dig into the CPU related items I and others had suggested? You didn’t post the FPS counter with your most recent results, but I presume you are still CPU bound like in your first screenshot. In that one, your GPU was barely working, but you seemed to be focused only on GPU related changes and that’s not going to help much at all.
Fyi it was earlier mentioned you were rendering in 720p and you didn’t know why. It’s because you’re running DLSS in ultra performance mode. DLSS, FSR, and the game’s own render scaling option will render internally at a lower resolution, then upscale it to send to the monitor. The result can be increase frame rates when GPU bound at the expense of image quality. The amount of trade-off depends on your setting. In your case, you aren’t benefiting at all because the GPU is waiting on the CPU all the time.
Agreed, and even then, with that setup he could perfectly not use DLSS at all, and should be getting 40+FPS in most if not all scenarios, which is more than adequate for a flight simulator.
Hi and thanks all for the suggestions. I had walked through almost everything suggested and found a fix, but in hardware, not software. I did make most of the changes talked about but it was my connections that seemed to make the difference.
I rearranged my dp and hdmi monitor connections, moved my 2 popout screens to the two internal ports on my Asus MB (forgot they were there!) and the changes using DX11/TA on Ultra are now at 40-45 regularly at 2560x1440 on all main screens.
Happy Camper - really just took walking through all the variables to see what clicked together. Thanks for all the replies!
