25-32 FPS with 2080 Ti and 9900K CPU

Hello everyone, just installed the simulator today. I have a high-end system. But trying to fly with Cessna 172 and in the cockpit, and even without taking of standing still, the FPS is around 25-32 FPS. When flying it’s still the same.

PC specs are:
i9 9900 @ GHZ
2080 Ti
64 GB Ram
144Hz monitor

I have the latest nvidia driver as well.

When I check for the optimization suggestion videos on youtube, most of the players get better FPS like 50+ while with even a 2070 VGA card.

I turned on the FPS monitoring tool in the simulator. (I don’t have the Steam version) It mostly stays in red and says limited by mainstream. When I’m in the menus and not flying, FPS is always green and above 100+

I don’t know what to try. When I ask about this, everyone is suggesting me to tweak the settings like turn off vsync and reduce that etc… but, with my settings I don’t think I would need to do that to gain an FPS over 40 or 50 in a Cessna.

What should I be looking at?



What is your internet speed like?

It’s 100 Mbit. Speed is good.

FPS in the air?

Also, have you tried the “pop out map and move to other screen” trick (if you can) that normally gives a healthy FPS boost.

It’s the same.

Do you mean press V during flight? Or something else?

Limited by main thread indicates that there is a bottleneck on the CPU side. The Sim is CPU intensive not GPU. Maybe try some tweaks on the motherboard.

try to monitor CPU frequency and temperature

At this point, I’d suggest benchmarking your PC with a popular benck mark app, and compare results. also, watch Temps. there is deffo something wrong here, but I can’t put my finger on it, this is leading me to thing thermal throttling (absolutely could be wrong on this)

How can I monitor CPU within the simulator?

https://www.cpuid.com/softwares/hwmonitor.html is a really good app to monitor pretty much anything

Yes I have it. I just don’t know if I could bring it up in the game. I think to check the cpu I should exit from Full Screen mode to bring the CPU ID windows up right?

That’s a bit weird because I have a 980Ti sli (and I guess Sli isn’t supported yet), i7 5930k 6/12T 32GB ram 512GB Nvme 960 pro and i have better results. Also have FTTH internet connection.

I’m in High End settings and i have your values when I fly in the middle of downtown NYC :smile:

Try to use CPUID HWMonitor to check your CPU/GPU usage and T°… I have to say that I’m pretty amazed at the low temperatures, my GPU never goes above 80 degrees.

Hope you could find your perfect settings, but there’s something wrong…

You should be able to just Alt+Tab to get to it, although if you start HWmon, then run the sim, then close it down, you can look at you maximum measurements within HWmon and see if anything looks too hot (personally certainly ang gpu/cpu reading about 80deg C is cause for concern). But alt tab should be enough to see if anything is a problem,

addendum I’ve had a beer, so I may not make sense.

unrelated to OP I also run 2x1080 sli, but I found sli makes things much worse, unfortunatly I think SLI is not going to be beneficial with MSFS. Absolutely turn that off if you can.

I run a Ryzen 7 3800X
32GB 3200MHz DDR4
X570 MB
Nvme M2 SSD
1Gig internet

I see a pretty consistent 40FPS on High or ultra anad CPU / GPU temps hovering between 60 and 70 degrees.
definitely nothing wrong with that.
I am also running 3 monitors at 1920 x 1080.

Thanks man, I will bench it on the same flight condition without sli activated. I’m curious to know your FPS values and on for what settings with your 1080…

BTW the 3090 The 3090 is coming out in a few days :stuck_out_tongue_winking_eye: :stuck_out_tongue_winking_eye:

I know avery useful mini softwrae (DeskPins) which is very useful if you want to keep a window always in the foreground
