How are you limiting your frame rate?

[ShezA 176]

Try the frame rate limiter in the MSI Afterburner/ Riva Tuner SS. Works really well with the unlimited setting. RTSS/Afterburner also has some other great features where you can monitor key GPU/CPU parameters on screen.

Yes, I'm surprised so few say they use it. I use P3D UNLIMITED, NO VSYNC, NO TB but RTSS ScanlineSync x/2 and it's great. And when I want to monitor performance MSi/RTSS has a great on screen display I can turn on and off.

I will try that next.  NvCP's Max Frame Rate of 30, using unlimited, vsync/TB disabled in-sim, and left the screen at 60Hz, initially looked favorable w/ a solid 30fps but yielded a lot of stutters in a moderate demand scenario w/ ample CPU/GPU headroom.  Nothing so far compares favorably against unlimited/vsycn to a 30Hz capable screen.

Are you running in full screen mode? (I know it’s not true full screen) 

Do you have g-sync enabled for full screen only or full screen and windowed? 
do you have any other addon windows open and are you on single monitor? 
also, make sure you have vsync forced to ON globally in your Nvidia control panel. 
Do you have VRR selected in the sim menu? 
also, is your g-sync module working ok? Try the Nvidia pendulum software to test it. I once had a broken g-sync and the pendulum software confirmed if for me. 

Windowed mode (But also seems in full screen), Gsync is enabled for full and windowed, single monitor, running v4.5 HF3 so I don’t have the explicit VRR check box option, Pendulum demo works fine.  All CPU cores on 7700K below 100%.

Does Low Latency Mode come into play does anyone know, for P3D?

And how about new "Hardware-accelerated GPU scheduling" feature in Default graphics settings?

Thanks.

Probably not a good place to ask for help but since we are on topic, I tried to limit at 30FPS in Nvidia but got flashing black screen.  Tried turning on Vsync and triple buffering, same thing.

So I went back to limiting in sim w/ no vsync and/or triple buffering and black flashing went away.

Thanks.

Low latency mode doesn’t work with DX12.

Possibly the magic trick is the new vrr setting in P3DV5 then? That’s what I’m using ..

What is the scanline sync setting you are using? -1?

Yes. x/2 parameter -1

OK for me it appears -2 is better. Will keep testing.

This works with v5 period

Unlimited fps in sim  ✅

VSYNC enabled in sim ✅

Triple buffer enabled in sim ✅

Monitor set to (30Hz Monitor) ✅

 

Flawless victory 🤩🤙🤪 in pretty much every scenario in my sim including areas where insane amount of heavy addons are present (all stress areas have 30fps)

And in v4.5, and in V3.4!

I have been following the work arounds for this, and for people who don't like 30Hz refresh rate.  Until today I had no luck whatsoever including using NvCP's Max Frame Rate limiter at 30 w/ considerable stutters, but today I had a very good experience, comparable to your configuration (and mine) using Riva Tuner's scan line x/2 w/ 60Hz screen w/ vsync/TB/unlimited in sim.  The difference largely being the core that does the main thread sits at 100% using Riva whereas w/ vsync to 30Hz this core varies according to load.  I don't know what that means except I can say as far as core temp they were very much the same.   The Riva method did maintain a steady 30 except once or twice and the flluidity was on a par w/ vsync 30Hz, but on a 60Hz screen.

A lot has been written on the core balancing. I have always used Process Lasso and it perfectly balances the load across whatever cores I assign to P3D. Right now I am using HT on (it helps in overall PC fluidity for other programs) and in PL I use HT disabled specifically assigned only for P3D. So for my CPU PL assigns physical cores 0,2,4,6,8,10 to P3D and 1,3,5,7,9,11 to every other process. I don't use the Affinity Mask tweak.

I tried the Nvidia Control Panel 30Hz option but default scenery was very stuttery when taxiing at default airports. Ridiculous when in that scenery I could get 80+ with no limitations.

Turned that option off and switched monitor refresh rate to 30Hz. Unlimited with VSync on and Triple Buffering enabled. Works much better now with no stutters at default airports. Used in P3D v3.4 and v4.5. Only downside is mouse action is a bit stuttery but I can live with that.
