Hi all, I have tried practically everything on this issue...I have a monitor that has a refresh of 75 with AMD Freesync, I have followed all instructions to get it setup within the Nvidia CP and Im also on the latest 517.48 Gameready drivers. No matter what I do there is a ton of screen tearing happening on MSFS2020 Should I just set my monitor to 60 instead of 75 the lock at 30? Would like to use the Freesync feature if I could...I tried the Nvidia G-SYNC Pendulum Demo and its smooth without any tearing on the G-Sync mode

My monitor is a Viewsonic VX2757 and my specs are listed bellow

Asus Tuf Gaming Plus B550
Asus Ryzen 9 5900X
EVGA RTX 3070
64GB DDR4 Ram 3600Mhz
EVGA 850W Power Supply
1 TB NVME PCIE gen 4
1 TB NVME PICE gen 4

Do you have Vsync off? I also have a Freesync monitor but mine has a refresh of 144. With Vsync off I'm getting FPS between 40 and 60 and no tearing.

Trying again, but yes tried with on and off

Same problem. Prior to Beta SU 11, I always had Vsync on but right after installing the BETA (with Vsync on), performance went to 15 fms and stutter city. This with every possible graphics setting allowed by MSFS with Vsync on. 

The only way to get back to my 30 fps. was to disable Vsync in MSFS. Now even if I set Vsync in Nvidia control panel, I get tearing in both 2d and VR. 

Using 2080 Super.

If you can set the monitor to 60hz, maybe try that with MSFS Vsync set to ON and 1/2 refresh which will lock you at 30fps.  I have a 60hz monitor and I have to run this setup to avoid screen tearing.  Another option would be to run Vsync set to 'Fast' in Nvidia CP and keep MSFS Vsync off.  Both of these worked for me but I stuck with running Vsync through MSFS.

That’s not the latest. In case it may help.
 

Had tearing too but could swear it stopped when I disabled VSYNC. Not sure though

Sorry I do have the latest one, its 522.25

Fast Sync is to be used when the GPU can deliver more frames than the monitor refresh rate. That's not his case here. He is not going to get more than 75 FPS, so Fast Sync is useless in his case.

And he has a Freesync monitor, shouldn't even have to use Vsync. 

I've played around with a lot of settings and I get a tear-free, flicker-free image with in-game v-sync off, g-sync off, and Nvidia Control Panel v-sync set to fast with no frame limitation.   I turned g-sync off because it introduces OLED flicker in dark scenes... turns out g-sync was doing nothing for me (I'm at 45-60FPS on a 120Hz panel).

(Not mine... copied from Reddit)...

Explanation of terms for those that are unsure:

V-SYNC - Framerate synced with monitor refresh rate (no tearing, input lag, increasing input lag as framerate lowers)

V-SYNC OFF - Framerate un-synced (tearing, very little input lag)

Adaptive Sync - At high framerates, VSync is enabled to eliminate tearing. At low frame rates, it's disabled to minimise stuttering. (input lag at high frame rates, tearing at low frame rates)

G-SYNC / FreeSync - Syncs refresh rate to frame rate (no tearing, minor input lag) (important to note that if maximum refresh rate is hit, G-SYNC will no longer be functioning so then input lag may be encountered if V-SYNC is enabled, input lag will not be encountered if V-SYNC is disabled but tearing will be) 

FAST-SYNC - De-coupled rendering and monitor refresh. VSYNC OFF but the monitor will only render completely rendered frames, thus eliminating tearing (MINOR input lag but NO TEARING! ) also it is monitor agnostic so it will work with any screen. It is analogous to hardware triple buffering but does not back-pressure the render pipeline.

It is a clever solution to the problem and requires very little overhead there should be no performance hit. It can still be used with G-SYNC for those that have systems that struggle to maintain FPS > refresh rate.

For me, although it sounds redundant, I have vsync on in both MSFS and Nvidia and that makes it look right. (SU10).

Nvidia fast sync appears to be best solution on my system - no tearing and minimal lag. I use Nvidia frame cap (58) and 144 Hz screen. It works way better than MSFS built-in vsync with respect to input lag. Unfortunately, Nvidia fast sync does not work with DX12.

VRR would be ideal, but I get annoying ghosting issues with frame rates under 70 FPS on my oldish Samsung monitor, so I don't use it.

I should add that I consider input lag to be very important because I use head/eye tracking (Tobii), which itself has input lag, and when I add the input lag from normal v-sync (either MSFS or standard Nvidia) on top of that, the camera movement lag becomes uncomfortably noticeable. People using mouse/joystick/gamepad for panning and camera movement might not have this issue with normal v-sync.

Unfortunately, there's another issue with Nvidia's fast sync - it causes MSFS to soft freeze with the Edge browser open on the same screen if using hardware acceleration. This can be solved by waking up MSFS with Ctrl-Alt-Del, so fortunately no hard restart is required, but it gets annoying when it happens.

Huh? That's exactly what g-sync is for.

Yeah, tell me about it. I bought an LG OLED specifically because it had G-Sync. But unfortunately, the only effect I could see was that it induced OLED flickering on dark scenes. Having G-Sync on or off made no difference to tearing as v-sync fast takes care of that. I really don't see the benefit of g-sync, at least where v-sync fast is an option.

I haven't got on DX12 yet. I wonder why v-sync fast doesn't work on DX12.  Is that global or isolated to MSFS?  Is it a bug, or will never work on DX12?  It's a real shame as it seems like the ultimate choice for tear-free, flicker-free refresh for me.

It is a Nvidia thing: https://nvidia.custhelp.com/app/answers/detail/a_id/4160/~/does-fast-sync-work-for-all-games%3F

The issue may be your freesync FPS range.  I can't find any hard specs on what it supports but for instance my LG 34GN850 needs 46 fps or higher to stay in freesync/gsync.  For comparison my other monitor a 27" Asus with an actual Gsync module can stay in gsync down to 27 fps.  So you need to stay above your monitor's minimum gsync/freesync FPS range to keep from getting tearing.  Your system should be more than capable of that in most cases, though you may need to turn down some settings a bit if you have a bunch on high/ultra.  My 5950X with a 2080 Super which should be pretty similar to your setup can drive a 34" 1440p ultrawide from generally upper 40's to my cap I set in the nvidia control panel of mid-50's without issue with mostly high, a few medium, and 1-2 ultra's in the settings including with weather, PMDG/Fenix/etc, unless I hit a really heavy weather or scenery area like say central London around EGLC for example or premium deluxe's KATL.
