We just had a 3 day lockdown which gave me an opportunity to experiment with a 2070 super, 3080 and 3090. I built 3 almost identical machines all with same type of ram, asus x570 boards with 3950x, 5900x and 5950x cpu's. I've been trying different combinations with the parts and drivers etc. 

I understand there's not meant to be much "gaming" performance difference between the 3080 and 3090, but I can barely get a 2% improvement over the 3080 and it's basically performing like it's the same card? 

Have any 3090 users found there's anything unique they had to set for the 3090 to max it's potential in MSFS or other games?

I also found what most people have been saying, that the random stutters are mostly present on the 3080 and 3090. As soon as I put the 2070s in the same PC, the frame rate drops as expected, but the random stutter / pause is gone. Driver doesn't seem to have any influence on the stutter. I'm not maxing out any CPU cores with any cards when it happens.

One of the Asus Rog Strix X570 boards is the F (my existing board) while the other two are E versions. My HP G2 will only run from the USB headers on the F version of the board.    All of the E version ports give the common headset error 7-14

What monitor or VR headset are you taking on?  Sounds like your cpu bound therefore the 3090 isnt going to show much differenece until the performance improvements come out with Sim update 5.

Hi Precog. Reverb G2 is the VR I'm using at the moment. I haven't done any comparisons in 2d as I never use it.

I've been monitoring each core in win resource monitor and at no time have they got above 70% with my MSFS VR graphics settings (everything is up high). Maybe the resource monitor is inaccurate and there are brief spikes happening that don't show on the graph?

Is your gpu at 100%? If so,I'd expect more than 2% I provement from a 3080 to a 3090.  I have a G2 with my 3080 and with my settings I'm GPU limited.

yep gpu is limited. I'm floating back and forth between 28-37fps on average in VR and WMR openXR, with both cards in MSFS. 

The same thing in starwars squadrons and project cars 2 between the two cards in VR, although they both achieve higher fps than MSFS. I would have thought I'd see a little bit more between them. Maybe there's a larger gap with some of the other games like Cyberpunk.

This is on average the same FPS which I get on my Oculus Rift but with only a 1070 ti.  I think that shows how much the game is unoptimized at the moment. According to MS it should be much better in the next sim update. 

Anyway, 28 to 37 fps on the MSFS ingame display should be quite smooth in VR. Those ministutters, do you have them always or is there a difference on looking directly straight over the planes nose and f.e looking directly to the side, like left wing ? For me that was the case and I had only ministutters when looking sideway to the wings, after I put ASW off in Oculus Tray tool, this problem vanished and now its always absolutely smooth. Maybe your VR headset has similiar options ? Also on which plane did you test ? I would recommend testing on small planes like C152 or the ultra lights, bigger airplanes are not optimized for VR yet.

Hi Rucki. I've only tested msfs using the two helicopters, though the small performance difference between the two cards is happening in all the games I've tried so far.
