I asked you to do that to see if your CPU could manage at least 45 FPS anywhere in any plane anytime because very likely that’s what I’ll be doing when I upgrade my CPU unless all these visual aberrations magically disappear which I sort of doubt they will and again the two screen issue is ginormous for me, so very likely I will stay out of frame generation, unless somehow that’s addressed as well.

For the longest time I was running 97fps with FG which is 48.5fps pre FG and my CPU temps were always very good thanks to the air cooler and the case I have. Would it stay there 100% of the time? No of course not but that is where having a display that supports GSYNC comes in. Even dropping the fps to 80 I still get the occasional dip as I did this morning to 70 but it is never significant enough that GSYNC cannot keep up with it. When you talk about these visual aberrations with FG I must be the luckiest person out there because I have never had a single one of them from the day I installed my 4090 to this day.

Do you use 2 screens?  You must be lucky because what describe is not unique to my testimony.  Cpt Piett reports it, sniper1 recently acknowledged strobing and many others on the FS forum.  Here’s a simple test you can do: back out of gate B 45 at KDENheading east at about 730 to 8:00 AM.  Use your default settings and pan the cockpit back-and-forth so that you can see the tarmac out the left side of the plane. When I do that at that hour with that light coming in, I get nasty strobe with any movement that’s the plane moving or panning. And if FG is turned off, all of that goes away, as well as the notorious glass cockpit aberration.  The latter is the least of the issues and I would put up with that if there were no other significant issues.  So try it with FG at 80, then turn it off and see if you notice any difference.

Long post warning!!

After tuning and tweaking, and then some more tweaking, inspired by Richard and Noel, I finally found the Holy Grail Settings for my system. 

Goal: Locked FPS at 80 with as much consistency in fps and frame times (i.e. smooth!). 

Method: Tweaked the settings to bring down main thread frame times which were my biggest limitation by far. 

Result: Consistent fps and frame times in Fenix V2 w/ FSLTL in real weather over France  at FL240 descending FL190.

Approaches into major hubs w/ AI traffic will have more stutters as main thread will be hammered. Having done a capture during ILS 26L to Gatwick I got average fps 74.3, smooth 99.7% with FTV <2ms at 91.4%. So I'm not able to smooth things out completely in these kind of situations, but I can definitely live with that kind of performance. 

Hopefully the following settings might be useful, and I'm now back on the thread topic 🙂

System:

• FPS locked at 80 in RTSS with front edge sync
• Process Lasso: FSLTL assigned to E-cores, everything else default
• Hyperthreading turned on in BIOS
• AutoFPS with target FG-FPS 75, TLOD max 300 (TLOD base 1000 AGL), no autoOLOD, auto cloud quality on
• Proton VPN at best server for Bing Maps streaming (depends on server congestion)

NCP global: 

• G-sync windowed and full screen
• DSR at 1.78x DL
• DSR smoothness: 20% (0% = sharpest image)
• Resolution 5461x2880 at 120Hz (native)
• Max frame rate: off
• Preferred refresh rate: highest available
• Shader cache size: unlimited

NCP MSFS:

• Anisotropic filtering 16x (off in sim)
• Low latency ultra
• Prefer max performance
• Shader cache size: unlimited
• Negative LOD bias: clamp
• Texture filtering: high quality
• Trilinear: on
• Triple buffering: off
• V-sync: on 

Nvidia Profile Inspector global:

• Force G-sync on window + full screen
• DLSS 3.1.11 DLAA: off
• DLSS 3.1.11 preset: F
• DLSS 3.1.11 scaling: 0.80x
• rBAR feature: enabled
• rBAR options: 0x0000001
• rBAR size limit: 0x0000004
• Memory allocation policy: 0x0000001 moderate pre-allocation

MSFS:

• Full screen
• Resolution 5461x2880 (same as in NCP for G-Sync to work)
• DLSS in ultra quality mode
• FG on
• TLOD controlled by AutoFPS
• OLOD 200
• Anisotropic filtering OFF (16x in NCP)
• Glass cockpit refresh rate: medium
• Rest of settings ultra/highest
• Photogrammetry on
• Rolling cache off

Usercf.opt:

• Shadows Size 6144

Image quality:

I find that for me, DLSS ultra quality at highest DLDSR resolution possible (for me that's 5461x2880) gives an absolutely razor sharp image with no blurring or ghosting whatsoever. With G-sync correctly configured, panning is butter-smooth.

Haha, just like tweaking. I actually enjoy it, lol! Been tweaking whilst flying though, so I guess that's a win-win 😅

Now stop tweaking and fly and enjoy the sim 🙂

Glad you finally made it to the holy Grail lol, welcome it truly is a wonderful place

What do you gain by having Anisotropic filtering off in game and on at 16X in NCP, doesn't the game use 16X as well?

Not much except for slightly better AF quality. It's subtle, so this is based on personal preference.

Thanks, I have the same card and I undervolt mine, I get little better performance and the card draw less power and runs cooler, take a look at this, I use his performance settings.

Thanks for linking that vid, I am now using his settings and my card is running approx 4-5C cooler.  This will really help this summer when my room will get a little warmer.

Ok that is decent news.  You did 7850X3D?  The absolute worse rate for me now is around 34 but 95% of scenarios its 100% stable at 38.  4090 seems to get more out of the 9900K than the 3080Ti did. I have Gsync but I rarely ever dip below the lock. I have to think with that CPU I should be able get to 50 rock solid the way I'm set up.  And for the rock solid razor sharp image quality 50 would be way good enough.

Did you try the test?  Did you verify there was no change in image quality with panning and taxi out the left side on the tarmac heading east after pushback out of gate B45, with FG on and off, they're identical?

 

 

 

I use TAA with FG MOD and DX12. Graphics quality is my top priority. I don't like any of the DLSS modes since it makes the cockpit panels blurry.

I think most simmers have the same opinion as you. I’m also a graphics quality aficionado, and find that upscaling the resolution using DLDSR then adding DLSS in ultra quality gives an even better image quality than TAA in 4K.

So its better to use the FG mod with a 4000 series GPU that has DLSS and Frame Gen? Never knew that

Does it beat TAA RS 160 do you think?
