Read on the thread. I don't believe you set vsync in the sim with DX12 und FG, because it doesn't work, at least not here.

Yes, I had just read your OP and had responded. I never use DX 12. So I would not know if it works or not. I will now read the thread and see what you discovered. 
-B

If you are not using DX11, then frame generation is not possible? Or am I missing something?

Update:

I also tried some different settings in NCP concerning vsync. There are big differences, most notably between using "On" and "Fast". On feels definitely like using 30fps limiter (DX11 + no FG + Vsync half refresh in the sim, NCP no setting). However, using Fast produces real 60fps feeling, really fast, no stutters when panning, however does produce a screen tear here and there (most notable when changing views in the cockpit). I think I'll go with Fast. Also menus remain very responsive with Fast.

Where / how do you set "framerate generation" ?

FG is that good i have no vsync or fps limit on. I have an issue though with gsync which causes flickering, due to DX12 i believe.

Keyword: GSync. Not everyone has that.

Change to DX12, turn on Hardware Accelerated GPU Scheduling in the OS, and set Nvidia DLSS Frame Generation to On in the Option menu. Requirement: 40-series GPU (says so in the sim).

yeh i have it disabled due to the flashing issue, and its still all smooth

But one thing I must say after testing this. It doesn't feel really like 60 genuine fps.

Frame generation doesn't generate "genuine" frames.  It's interpolated frames generated by the graphics card (using AI I think), not actual frames generated by the game.

It's still pretty good, IMO.  You get a smoother experience overall with frame generation setup properly, than no frame generation at all.

 

That is true. However, I see, on my setup, it's more than this. Apparently, I always had Freesync disabled on my monitor, so I enabled it now, tested with Pendulum and now will try MSFS. Seems it does require a certain combination of settings.

Hello,

I just discovered framerate generation with my 4080, and virtually had my jaw dropped, going from some 35fps to over 80 (didn't A-B compare, but the situation on stand the same stand at EGLL (no addon), Fenix, cockpit, weather).

Anyhoo... while 80fps is GREAT, stuttery sim without VSYNC and frame limitation is worse than anything else.

I tried limiting with RTSS, but it's worse than bad. VSYNC in the sim doesn't work any more, no impact on the FPS.

Is there something recommended please?

Example 60HZ TV

FG on in the Game
In Nvidia panel: Max 60FPS and VSYNC on.
Smooth as butter

I think I reached pretty much my maximum:

GSYNC Compatible + Low Latency Ultra + VSYNC On in NCP.

Freensync enable on my screen.

No VSYNC in MSFS. FG on.

No tearing, pretty much stutterfree. Stable 58fps due to Low Latency Mode, otherweise it would go to 60fps, I believe this is the key.

Reference-post:

This is what I've been waiting for since like 20 years.

Now trying to break it, see what happens when FPS drop below 58 🙂

Definitely missing something. FG works great in DX 11. Perhaps the FG selector is grayed out for you, then you simply enable it in user.cfg (DLSSG=1).

That is one thing I prefer not doing. With DX11 natively, FG is greyed out.

This is the way to go… If you don’t have a display syncing frames with G-Sync or Free-sync you need to use NV CP V-sync set to fast. It’s nearly as good as a hardware solution like G-sync at eliminating tearing with minimal added latency. 

If you have a G-sync or similar display, v-sync is only relevant when FPS > max refresh rate. So turn v-sync off in NV CP and set your max FPS to 3-4 less than your display max refresh rate. That way FPS never exceeds max refresh and v-sync is not needed. G-sync will ensure a tear free image. 

Never use in-game v-sync as it is a latency filled nightmare.
