I followed all those settings. I do use riva tuner but just to show the frames only. Maybe I'll try to just not have it running at all. Did you notice the jitters towards the landing of my last video? I'm on a 60mgz monitor. The monitor can run 75 megahertz, but I choose to keep it at 60 since my monitor on the side can only run at 60., It's a different brand and not the same monitor. . I don't know if that matters or not.

I haven't watched the video yet but I will,

Just exit RTSS completely and see if the stutters go. I now use the HWINFO plugin om my Streamdeck XL to monitor System info so I do not use RTSS anymore

But at what cost, a 4090 is not cheap, hopefully AMD can give it to us at a better price.

Get a 4070 or 4080 then? Way cheaper than 4090.

Keep frame generation on, it's absolutely game changing amazing.

Yup, you gotta see it to believe it. No more fighting to achieve frames or locking at 30. That’s a relic of the past now.

I have it turned on and it allows me to run three 75" monitors at 4K while also running an additional four monitors for my glass screens. With it off I'm limited to 2K on my external views.

Not directly related to the OP question, but looking at this video is the first time I can actually see the attraction of people getting seriously into the whole airliner/cockpit/serious simming stuff. A setup like that makes sense of it all - very impressive! Thank you for posting this.

Don’t use RTSS/Afterburner. Use NV Performance overlay (GeForce Experience). Or your TV/Display info/status overlay.

Turn it on. I can’t stand less than 60FPS. I’ll take the occasional dropped frame or stutter over having to live with 30FPS constantly.

Key settings to check:

• Make sure you have G-Sync enabled for both full screen and windowed mode - critical if you ever have a pop-out or other window up
• Enable V-Sync in Nvidia Control Panel (this with Reflex/DX12/FG (below) will cap your FPS at a few below your max refresh rate automatically)
• Turn off any and all frame limiters (Nvidia, game, etc) - not needed 
• Disable V-Sync in game
• Enable DX12, Frame Generation, Reflex Low Latency (they’re all interrelated)
• Try using DLSS for anti-aliasing vs TAA. DLSS can provide sharper details at a distance while TAA can lose these details completely, but DLSS may be slightly less sharp on instruments. 

 

tried your settings and working like a charm... thank you. (Do not forget enabling v sync in ncp.)

I have a 4070Ti, but 12GB VRAM is not enough at high quality add-on airports, and I have read that the 4080 with 16 GB is not enough either, especially in 4K.

I said this years ago, more VRAM is needed. Especially as we go 4K. 

I wish some manufacturer would release a card with expandable VRAM slots... But I'll keep dreaming...

FG works outside of major add-on airports with my card, but I see no reason to use it as I already get around 70fps without it, and in DX11 there is no problem with lack of VRAM at major airports either.

I have an RTX 4070 and my only issue with Frame Generation is the constant screen flickering.  Someone else said to turn off Flare or Bloom or something, and I did that, but to no avail.  And yes, Gsync is enabled.  I run TAA because I can't stand the blurry gauges in DLSS.

I'm confused reading some of the posts in here how you guys are getting VSYNC to work with FG on. 

I'm using 3 x 4K 50" TVs. Turning VSYNC on or off in the NVCP (or MSFS) does not actually have any effect on my system. Maybe its because of the triple monitors (I'm using three rendering windows via MSFS experimental settings as opposed to NVSurround) but I'm sure even when I disable the site monitors and just use the one rendering window (main screen) there is still no VSYNC when using FG.

There are a number of threads about this on the internet and no matter what combination of settings I try and can't get VSYNC to work. It important to me because I want to cap frames and ensure a stutter & tearing free display which requires V-SYNC (I don't have G-SYNC or FREE SYNCH or any other SYNC on these screens).

To answer the OPs question - I use it off for the above reasons. From time to time I put it on however FG only works on one (the main) rendering window so on a triple monitor setup you get smooth frames on the main display but without v-synch you can get tearing and stutters on the side displays. Its a little annoying. 

What I've also noticed is that FG does utilise a bit of main thread power. Turning it on my centre screen probably costs me 2-3 FPS on the side monitors. FYIW.

First off, there's no such thing as a stutter free experience in this game 😛  Tear-free, yes; stutter-free, no.

If you don't have G-Sync, you're just not going to be in an ideal place. It's interesting that you've invested in the absolute premium CPU and GPU but not G-Sync?  I'm not sure G-Sync works on more than the primary display... it only works on the "active" window or fullscreen game so I guess it depends how Asobo implemented multi-monitor support. But even if each MSFS display is a different "window", the main display is probably the most important anyway. 

You should try V-Sync FAST in NV Control Panel. That's what I used to great effect before I got G-Sync (but it was also before I get a 4090 with FG). That might help any tearing you're seeing... Dunno. You can also set a frame limit in NV Control Panel to 3 or 4 FPS below your refresh rate, or maybe even in game.  Although Frame Generation with Reflex and V-Sync on in NV CP should limit your FPS to less than your refresh automatically. At least it does with G-Sync. You really need to get G-Sync for the best modern display experience.

What is the refresh rate of your displays? What FPS are you getting?

I recommend anyone who wants to take a deep dive into these topics of G-Sync, V-Sync, Frame Generation, and Reflex Low Latency spend some time here.. https://blurbusters.com  The site is widely considered the authority on all things Nvidia.  That's where the settings I quoted above come from as a best practise.

Hi Bill,

As Virtual-Chris mentioned these are the settings I also use:

I use the above with my 55 inch Sony X90K @ 100Hz and the sim is as smooth as butter. Are you by any chance using or have used RTSS to cap frames in the past? RTSS does not play well with FG and I found when trying to use it small stutters were introduced. It is not still trying to set fps in the background is it?

I think I have CTD's with DX12. At least I did the last few times I tried it; Do these steps work for DX11?

Not sure... you can try them, but the whole basis for these settings are a combo of Frame Generation (DX12), G-Sync, and Reflex and how to minimize tearing and deal with FPS > Refresh Rate.
