I found this video just in case you were wondering how it looks with an rtx 3090.. For me looks great but not what i expected.. 
 

 

There are so many factors that affect overall experience.

The sim looked just as great on a 2060 as it does on 3090.  A bit of smoothness came with running the latter.  CPU is still a big consideration.

He has pretty ordinary settings for a 3090.

For example his Texture Super Sampling is only 6x6, his render scaling is only 100 and the LOD is only at the GUI max of 200 .

He has also chosen to film near dusk, which may well be atmospheric but creates issues with big shadows and is washing out the scenery at altitude.

 

Upgrading from a 1080 to a 3090 has improved my experience very nicely; frames from 20-30 with most settings on high, to 40-60 with nearly everything on ultra. The clouds on ultra are stunning in some quite subtle ways, ground textures, water, reflections, shadows, everything really stunning.

But still the devmode counter has me as GPU bound🥴

My shift to a 3090 from a 2080Ti had me go to being CPU bound a lot of the time by my 9700K (at 4K). The recent update shifted that back a bit although photogrammetry is still CPU bound. I’m m now looking to get a Ryzen 5900x to unlock more performance potential.

I am not impressed either, I have similar framerates at 1440p/Ultra with 3-4 year old hardware. And the reason is always the MainThread curse, affecting flight simulators since the dawn of times.

After 4'36" you can see how the GPU usage and the framerate drop (even below 40 fps!) while 2 CPU cores are maxed out.

The youtuber could have done better by disabling 8 cores out of 16; in the future with DX12 the situation will hopefully improve.

From what I understand, I would gain 8-10 fps on upgrading to a 3090, it's not worth it considering that a 3090 would cost me about $2300 where I live. (Sweden)

I have a 3070 which is great for HD.  If I was running 4k I would have gone for the 3080.  A 3090 would be great, but the expense would be overkill for MSFS I feel.  For me, A CPU upgrade from my Ryzen  2700 to a 5600x is my greater priority.

The AMD graphics cards look interesting though.

I don't understand why so many people are interested in the 3090. You get 10% more FPS at best compared to the 3080. Save the 800$ & buy a 3080 now, and a 4080 in 18 months.

I do get that, and for my panel it’s almost certainly overkill for most gaming. But I don’t have any other very expensive hobbies (except maybe the odd bottle of moderately-pricey wine) so a once-every-5yrs treat which might also give more than 10% for some situations (esp. VR) is a justifiable luxury. In my self-affirming logic...

Obviously at the end of the day, you are your own master of coin & I understand the logic 🙂

Vram is another example f why. Especially for those of us still doing most of our flying in P3d. When msfs goes dx12 vram will be important here also

That's my main concern with my RTX 3070.  Only 8 gb of VRAM and I know from past experience, flight simulators do like a lot of VRAM.

I've seen my 3090 chew up above 10gb of Vram.  Question is what significance does 8gb limit have on performance when using fast cards that 3000 series are...

That's why if I can get one before a 3080, I'd rather have the 6800XT.
