Hello, i have been researching the advantages of limiting for a few days but never limited frames before and now really confused applying to my PC.

I turned ON V-Sync both in-game and NVCP. Monitor's G-Sync ON. Locked fps to 60 in NVCP. FG ON. Set monitor's hz to 144. Did i applied right because i'm confused on the setting frame limit option in sim which appears %33-%50-%100 ? Set it to %100 currently. 

Or is it enough to just lock the frame to 60 from NVCP and turn ON the G-Sync?

My specs; 

7800X3D

64GB DDR5 

RTX4070

2K 144hz G-Sync Monitor

Set your monitor refresh rate to 120Hz, lock FPS with MSI Afterburner to 60FPS with Front Edge Sync, disable G-Sync in NVCP and in game and enable FG in the sim. That's what I do and it works very well, always 60FPS and no stutters with DLSS set to Quality. I don't use any apps like Auto FPS and the like.

You can just use nVidia control panel, without any 3rd party app.

The settings recommended by blurbusters and universally accepted as the best, are:

• GSync on in nVidia control panel
• VSync on in nVidia control panel
• VSync off in game
• FPS limited to monitor refresh rate -3 (I limit them to 60 because it's more than enough for FS and to save my ears from the RTX 3090 fans)

 

 

If you are using frame generation, it enables low latency mode, which should stop your frame rate ever exceeding your monitors refresh rate.

Whats the VRR range of your monitor? 

Don't turn on V-Sync in game, ever.

Why?  I get tearing if I don't...looks awful when panning.

Turn it on globally in the NVcontrol panel.

Gotcha...I'll try in NVCP instead.  Anything different I should expect?

It is normally what is recommended through various tests over the years. 

Also,  for new cards DLSS3 Frame Generation is best experienced with Nvidia Control Panel's VSYNC On + G-Sync ON + no framerate limiters since Reflex limits FPS for you.

Its Asus vg27aq, 60 to 144hz (165 with oc if i'm not wrong).

Ok i'll turn off the in game vsync off then. I thought both ON overwrites each.

I use FG but fps exceeds hz of my monitor (using 144 currently) airport to airport, 160 sometimes 180 fps.

As @Alvega states using RTSS' Front Edge Sync along with enabling G-sync if your display supports it delivers the best of all possible frame limiting options as of extensive testing done in late 2022.  Here are its major benefits over v-sync and NVCP:

1.  Delivers the consistent lowest frame time variance.  The lower the frame rate is, the more low FTV matters at it plays a major role in the perception of smooth animation.  Once frame rate are very high it becomes less critical.  Here is an example of what exquisitely lower FTV looks like when captured by CapFrameX.  This was a native lock at 30, doubled w/ NV FG:

2. It offers runtime capability to adjust frame rate on the fly literally simply by user-assigned key presses.  It's helpful to be able to increase or decrease the lock while flying as you for example enter a super complex arrival.  I prefer keeping about 10-15% headroom over the frame lock so that for example if the wide-open native rate is say 50, I will set the RTSS lock at not more than 45, which doubled if I desire to 90FPS-fg.  Sometimes I will leave it at 45 w/o FG because image quality and stability is the absolute best over any kind of FG, but I pay for that with lower frames.  45 is still descent though I too am spoiled by higher rates, while at the same time detest some of the graphic artifacts that are associated with NV DLSS Frame Generation.  Anyway it's a nice feature not to have to restart MSFS in order to effect a change in the frame rate lock.

Thank you, i'm turning of vsync in game. One question; i shouldn't set my monitor to 144hz while i set the max frame rate to 60fps in NVCP right ? Both should set to 60 ? Rarely i play BF2042 that's why i wanted to ask.

FG can't exceed the HZ of your monitor as it uses ultra low latency mode by default, which SHOULD cap the frame at slightly below the max refresh rate which in your case is 144.

Your G-Sync will only work between 60-144FPS if thats it's VRR range, so, I wouldn't cap at 60, because if you dip just 1 frame below that, G-Sync will disengage and then re-engage, causing a shudder effect. You need some head room, try capping at 65... 

 

However I have a question, if you are pulling over 120FPS, why on earth do you want to cap it? It should be smooth and stutter free, as Noel has alluded to in his post above, the higher the FPS, the less you notice frame time variance.

You can keep your monitor at 144 Hz, it will run at 60 with GSync on anyway. So you don't have to change your refresh rate when you return to the desktop.

Thank you very much for such detailed information, i'll take a look at your thread this evening and try to tweak.
