I have a 12700K/3080Ti. Currently trying out DX12 and DLSS Quality at 4K with TLOD at 245.  I flew into FT KMIA in the PMDG 737 and performance was superb. I am locked at 30 (1/2 monitor refresh rate), but FPS never dropped for even a second - and absolutely no stutters whatsoever. I did get both FPS fluctuations and stutters at the same airport in SU9.

However, VRAM consumption is high. I did not run out of VRAM, but it was at 98 percent after landing at KMIA.

My personal taste for 2D would be 40-50fps minimum. The difference to me between 30-60 is noticeable. For VR, 30fps is great which is what I currently get around.

DX12 appears to be doing what I suspected all along for folks with powerful gpu and lots of vram. Smoothing the sim out big time.

How was performance before ? 

Good already.

I am not following FPS in the sims, unless it's XP11 and I have to ensure it doesn't drop bellow 20 fps, but in XP11 I usually get stable 60 fps.

In MFS I opted for 50 % VSync and I am more than good with it.

Just enabled Real Traffic and made a flight into LPPT - Wow!  

Anyway, might be placebo, but after all of my test flights, with and without DLSS, and mostly in XP12, I get the feel that the sim performs even more fluidly than it already did.

I feel like there is no point for me to use DLSS with my 3080 at 1440p....Thoughts?

I have to think DX12 uses as much VRAM as it can, but that does not mean it can't dynamically adjust to lesser amounts of VRAM.  Reports here seem to suggest you will use more VRAM than you did in DX11, no matter how much VRAM is on the card.   That's an encouraging report.  Do you find evidence of better utilization of your multicore CPU than w/ DX11?

When you run a higher resolution than 1080p you are less likely to notice the drop in image quality with DLSS and are more likely to get better performance.

Right now (in flight) cores 4, 5, 6 and 7 are at 100 percent most of the time, but they do occasionally drop to less than that. Cores 8 through 12 are about 20 percent. Cores 13 through 19 about 20 percent or even parked - same for cores 0 through 3

Is that significantly different than in DX11?

I never really paid attention to core use in DX11. I have only had this new system for about 2 weeks. Before that I had a 4790K/1080Ti

DX12 and DLSS at Quality : I can see from FRAPS that more cores of the CPU are being kept busier than before but in terms of FPS I can’t really tell the difference compared with before on my PC. VRAM use seems similar too. 
 

What I have noticed - could ofc be placebo -  is slightly different-looking textures (noticed the runway at EGLL: seemed more granular and rutted and convincing somehow), better sky/ clouds, better contrast / gamma and less/better nuanced saturation. 
 

this on a 12900ks 3090ti 

I could see the difference between DX11 and DX12 while using Fenix A320. I have the 11900k with adaptive boost at 5.1ghz and temps are much higher with DX12 because is using more cores ( better multithread process).

That’s probably one of the reasons it doesn’t stutter anymore? 

Any one seeing that the displays in the Fenix are less sharp with DLSS (quality) and DX12 enabled compared to TAA ?

Yes, even with DX11. I have turned DLSS off for now..
