My 2070 SUPER 4K settings and suggestions - episode 2

This should be a capable CPU when using reasonable and capable settings. Do you mean regardless of trying my suggestions, you were getting these fps issues recently?

If so, could this be you’ve updated your NVidia driver and this is the main factor to the loss of fps? I’ve validated my settings with at least 2 drivers: 446.14 and 456.55

Since you have a Gsync monitor, have you made sure to also review the monitor refresh rate in the NVidia CPL like indicated in my post?

I did recently update my NVidia driver, I will verify. My monitor is set up to max refresh 144Hz on the NVidia panel as suggested in your guide. Maybe be a driver issue. Is it possible to revert to the last driver used or one current one you have tested with these optimal settings?

hello i bought a 2070 Super recendly and tryed out the guide directrly because im following it since long time and upgraded from my 1070 and the games looks on high settings Awsome!! before i had 4k native on the nearly lowest settings to get smooth fps with my 1070 and now with the 2070Super on high its breaking my mind and i have stable 30 fps ( limited by myself) and even at busy areas nothing changes

Thank you for sharing your experience and enduring patience! I’m glad this is helping you get a better experience too!

Hi @CptLucky8, would you be able to explain more why you selected Low Latency to “on”? Reading up on it, seems it requires more CPU processing power? Seems backwards to me if we’re trying to load up the GPU more?

I will say though, in my own testing, Low Latency does seem to reduce the micro-stutters I get even at decent FPS.

So you definitely have my thanks!

In my initial post I was saying:

What I’ve realized is that if you set the simulator to 60 fps it ends up rendering for example in average 55 fps (60-a). But if you set the simulator to 30 fps it won’t render to 30 fps but around 27 fps (30-b), even though it is capable of rendering at 55 fps. In other words, by the time the simulator renders the frame and by the time it displays it on the screen, there is a ‘synchronization’ point which prevents rendering fast enough to reach the maximum fps limit you’re configuring.

Any game capable of rendering at 55 fps (30+c) is definitely capable of rendering at a fixed 30 fps, instead of (30-b) but it seems it is not the case with FS2020. I’m not sure whether this is a bug in FS2020 ‘present’ logic, or a limitation because they are using DX11 or anything else, but I’m sure it is not normal.

Otherwise, if you’re ‘buffering’ the rendered frame, you also need to store them in VRAM and this adds up in 4K. These buffers which must remain allocated will prevent the simulator from loading up all the resources needed for one frame (potentially) and will therefore cause the simulator to stream vertex and texture data per-frame. Therefore I’ve chosen disabling as much buffering as possible in order to free up some useful VRAM.

The overall combination is working good for this card because it frees up enough VRAM while not loading it up too much with the balanced rendering settings, and in effect, I rarely notice the simulator needing to stream data per-frame.

In most rural and empty areas you have room to raise some of the settings if you want, and in urban dense areas fps will drop as expected but not much.

The only drawback I’ve not found a workaround yet is that if you’re for example flying and looking down the aircraft vertically in external view over autopen buildings (I test over Nice - LFMN), you can feel micro hesitations when looking at the buildings and scenery passing by beneath the aircraft. It resemble a film which is skipping a frame from time to time (think a dent in the rotating wheel skipping the film stock hole in an old movie projector). It is however barely noticeable when looking from the cockpit or down even at 75 deg angles.

This effect is most likely due to the ‘fast’ sync and my hardware trying to push up, but conversely, this might be proving these settings are the most efficient because the CPU and the GPU are pushing as much they can.

[update] This is judder and you might want read the new Monitor Settings (Freesync/G-Sync) topic in the 1st post. It you do have a compatible monitor you can eliminate judder with this!

And I thank you for sharing you feedback, it will certainly help others too!


Wow! Thanks for the write up! Absolutely amazing!

I’ve definitely seen the microstutters that you’ve described.

Given what you said, I get that disabling vsync makes sense, but, does that also hold true for frame limiters? Like I have Nvidia CP set to frame limit to 30. My 4K fresh rate is 60, but I can only get to 45 or so max. Would disabling the frame limiter reduce stuttering? I guess I should just test it LOL.

Thanks for dealing with an ■■■■ retentive performance geek. :joy:

Thank you for your kind words! I don’t know the answer but I’m looking forward the results of your tests!

I’m not seeing any difference in stutters if frame locks are on vs off. It seems in my case at least, the more I can load up the GPU over the CPU, the smoother sim I get.

Not sure what I’m doing wrong but on my PC I’m only getting 19-20fps. 4K at medium high preset. Ryzen 3700X with 2080 Super, 16gigs Ram and all SSD. Should be better right? Latest FS update as of this morning. Any advice??

I am also getting good results from 452.06 driver. That is the last driver that Nvidia stated it was optimized for MSFS. The newer versions have been optimized for other titles. May have negatively affected optimization for MSFS. I’m sticking with 452.06 until a driver specifically says it enhances MSFS.


Yes, agreed. I tried running a newer driver and it seemed that I lost a few frames in my controlled analysis experiment. :slight_smile:

Update: I’ve just added the following sections to the original post:

My identical setup - would you be so kind as to confirm your exact settings? Hugely appreciated Richard!

I’d like to give this a try because everything looks awfully pixelated since the last patch, however, I don’t have a folder called Microsoft.FlightSimulator in my Packages folder…? I am using the Steam version. I see Microsoft.ECApp_### and then Microsoft.GetHelp_###: no FlightSimulator in between there…

Is the useropt.cfg located elsewhere when you are using Steam? I obviously searched for the file but Windows didn’t find it.

Mine is in here (Steam version):

Thanks LOL No wonder I couldn’t find the file with Search… It’s not called UserOpt.cfg but UserCfg.opt…!!!

You might want to change that UserOpt.cfg to UserCfg.opt…


Okay, next problem: the changed setting won’t stick. MSFS reverts 0 to 1 again everytime I start the sim. Should I make UserCfg.op read only or something? If I do I won’t be able to make or save other settings, will I?

Never mind. Made it read only, loaded the sim but sharpen at 0 still looks the same. And awful.

Shouldn’t this:
be rather this:
In my case with 1.10.7 even after applying “Sharpen 0” in UserCfg.opt and the recommended settings in NVC, the trees look overly sharpened.

Super interesting post right here!

My ring:
i7 7700
16Gb RAM
Ulatrawide 3440x1440

Settings in Flight simulator are a mix of medium and high, just with the exception of Ultra in clouds (possibly, the best of the game). Nvidia desktop settings untouched leaves me somewhere between 30-33 FPS in low populated/high altitude. Between 25-30 in NYC.

I just tried the sharpening function in Nvidia control panel and lowering the internal resolution to 90% after reading the post and I don’t know…anything beyond 0.1 in sharpening introduces a lot of artifacts, specially in distant objects or reflections.

I don’t know how you guys manage to get clean image with Nvidia Sharpening on. Digital Foundry also recommended it in their video but there must be something on my end which doesn’t allow it to show any advantages.

Besides that, great recommendation!
