240 - 300 fps instead 120 in fast sync

[Red_Pilot]

In both MT and ST when I use fast V-sync I see 240 - 300 fps 

although my videocard setting is 120. In others options of sync everything is ok (I can have exactly 120 fps). I can't imagine what is the reason for that. I use f-sync in DCS with in-game sync on, but if this one off result the same / videodriver  has been updated / DCS has been updated / W 10 / i7 / 3070ti / 64 RAM

P.s all others game also works in fast sync ok

where are you setting the limiter? in DCS or outside of DCS? Fast Sync itself does not limit FPS.

If you are using G-Sync there is no reason to have any form of Vsync enabled, fast or otherwise. Just cap your frame rate at your monitor’s rate or 2-3 fps below that. I’ve read that the in-game limiter causes problem plus it doesn’t allow fine adjustments, so this cap is best done in NCP.

I don't use G-sync

Ok I saw you’re using Nvidia, I figured a 120Hz screen would be VRR. Do you use FreeSync? I don’t imagine FreeSync needs Vsync enabled either.
How are you getting 300 FPS? It seems like you could just turn up settings to limit that. You can of course solve this problem by setting a max frame rate in Nvidia Control Panel

No FreeSync.. In IL-2 GB I get 120 FPS with fast sync and it works there as usual. It would be better gives you skrins of my settings, but currently I limited by the forum. And yes, 300 FPS because of DCS I think.

Well you can solve this by entering the value of your monitor’s refresh rate for Max Frame Rate in Nvidia Control Panel. If you see tearing try 2-3 FPS less. Although Fast Vsync is supposed to eliminate frames above your refresh rate, not sure why it isn’t working for you. And you could consider raising your graphic settings since your frame rate is so high, you could make the game look much better.
