March 25, 20215 yr Without changing anything that I'm aware of, I noticed today, my best frame rate was 30fps. This seemed odd, as on previous days I would see up to 40fps on my OSD even with the poor performance from the last update. What's odd, is that turning vsync off restored my occasional bump up to 40fps. What's even more strange, is that vsync (when on) remains set (unchanged) at 60fps which is the frame rate of my 4K TV monitor. I checked Nvidia Control Panel but there's nothing to see there - everything is default as it was a week ago when I put this new system together. What could cause vsync to ignore its own setting and lock to 30fps? Anyone have any thoughts?
March 25, 20215 yr Vysnc will try to lock your framerate to your monitor, if you have more than 60fps and your monitor is 60hz it will lock it to 60fps If you fall below 60fps it will half the hz of your monitor, in your case 30fps. This eliminates screen tearing and stutters as your video card would be pushing 50 frames a second and your monitor is outputting 60

That makes sense I guess, but I’m fairly certain I was running with Vsync enabled set to 60Hz just the other day and it was not capping my frame rates to 30.
March 25, 20215 yr There was a bug where the game vsync set to half the frame rate. not sure if it was ever fixed. The workaround was cap frame rate for MSFS in your graphics control panel for your GPU.

I get 15 FPS whenever i set ingame vsync to 30Hz and 30 FPS when set to 60Hz. 😄 Intel i9-13900K | Gigabyte Z790 Aorus Master | RTX4090 | 2x16GB Corsair Vengeance DDR5-6000 | Be quiet!

March 25, 20215 yr I am getting tearing, regardless of my Vsynch settings in Nvidia or MSFS (it's odd), haven't fully isolated it yet. I upgraded the same time this last update came out, so it may just be that I reset something, maybe I'll re-install the driver on the next update or something.

March 25, 20215 yr I have the same issue so I always leave vsync off. I have a freesync monitor though, which does prevent tearing as long as the frame rate doesn't dip too low.
March 25, 20215 yr I set V-Sync to 30 in game, and that gives me a maximum of 50 fps in the game as my monitors refresh rate is 100, it seems that setting V-Sync to 30 will lock your fps to half your monitors refresh rate., but it will dip down tp 30fps under heavy load, setting V-Sync in game is the only option that works for me without getting flickering after UK update, but it works just fine.

March 25, 20215 yr I set mine to Vsync 30 inside the sim. Waste of time - 8 fps on the edge of class B airspace! 😆 Edited March 25, 20215 yr by bobcat999 Rob (but call me Bob or Rob, I don't mind).

The workaround was cap frame rate for MSFS in your graphics control panel for your GPU. That would explain it. I have been away from the sim for a few months, hoping things would get better... boy was I wrong.

There is some talk of Nvidia adaptive vsync having behaviour like this. At any rate, the most plausible explanation is a bug. As there are certainly a few of those. 🙂
March 25, 20215 yr Author Interestingly, someone else has had the same observation as me over on the official forums... Quote You know I saw the same thing yesterday, that my FPS never went above 30, since the problems started though thats a good thing because before the problems I could hold 40 and after only 15, I think there might be something going on, on the server side which is limiting the fps/bandwidth your getting from the server… While I can't imagine it's a server side issue, it could be that something tends to trigger this vsync bug and both of us have triggered it at around the same time. Either way, it's ver strange.
March 26, 20215 yr I set my frames in MSFS to 60 with VSYNC on and a frame limiter in rivatuner to 45. I stays at 45 in most areas and keeps my GPU from sounding like a turbofan. ASUS Prime Z490-A / i7-10700K / RTX 4080 / G.SKILL Ripjaws 32GB / Lian-Li PC-O11 Dynamic case
