Hi,
I currently have a
Rtx 3080
Ryzen 9 3900x
32gb 3200mhz ram
Sabrent rocket pci 4.0 ssd
Would I benefit from upgrading to a 5950X cpu by a margin? I’m currently not happy with the fps (15-20) I am getting in VR and am willing to invest, but it has to be at least 8-15 extra fps. The 5950 vs 3900 reviews I can find are from end 2020 and flight sim did receive substantial cpu updates so I was wondering wether I would still benefit around 10 fps.
Thanks!
Have you tried the NIS scaler tool for VR?
you might gain a couple of fps but not 10-15. with a G2 with its high res the sim is gpu limited meaning its the gpu that makes all the difference, not cpu. check for yourself - look at the in game developer tools performance monitor. if you’re gaming at 1080p on a monitor then a cpu upgrade would help.
can u overclock your cpu? try that. i have a 5 yr old i7 7700k that does the job at 4.5ghz.
15-20 fps is low for your spec, what openxr resolution do u use? what msfs render scale do u use? what settings do u use in game i.e. are clouds on ultra etc?
In nvidia control panel set fps to 30 with v sync on and vr frames to 2 also I set my motion reprojection to 80 in openxr and 100 in game.
Ever since I did the 30fps thing its smooth as butter 30 feels like 60
My settings in VR are:
no settings in openXR / dont use it
Ingame
Render scaling 80%
AA: TAA
TLOD: 200
terrain pre caching: low
terrain vector data: high
buildings: high
trees: medium
grass: low
OLOD: 100
volumetric clouds: low
texture resolution: ultra
anisopotric filtering: 16x
texture supersampling: 8x
texture syntesis: ultra
water waves: low
shadow maps: 768
terrain shadows: 256
contact shadows: low
windshield effects: medium
ambient occlusion: off
cubemap reflections: 128
raymarked reflections: off
light shafts: off
bloom: on
glass cockpit refresh rate: low
with these settings, I get around 30 FPS
I did not turn off HT/SMT in bios, should I?
In the FPS counter, the upper right block turns reddish, the 5 below are green and the bottom one is red. I don’t know what all these blocks mean?
Thanks for helping out!
I’m not sure, sorry.
30 fps isn’t alarmingly low. I suggest trying the NIS mod, i was too was getting about 30 fps, it gave me an extra 6-8 fps.
With 70% scaling and 90% sharpness it gives me about 3-4 FPS but the game does in fact looks worse, so I put it back…
edit, I also used the Nvidia NIS tool, uninstalled it and used the original microsoft openXR tool and instantly got 45FPS wit the same settings. went up with a lot of things to high/ultra, and am now on 30FPS 
I’m a bit confused as you first say this:
Then this:
Which one is it?
Also, you say:
If you don’t use OpenXR, does that mean you are using SteamVR? If so, use OpenXR instead as it is gives generally better performance in MSFS.
In any case, my system, which is similar to yours but has an i9 10850K @ 5.2GHz (hyperthreading off), performs very well in MSFS VR, especially since the last nVidia driver update to 511.23. With the following settings, I was pulling 28-35 FPS yesterday with the FBW A320NX on a group flight with about 20 people from ORBI to OMDB:
OpenXR:
Render scale Auto (which works out to about 80%)
Motion reprojection disabled
If these such views show your CPU is the one limiting performance, then a CPU upgrade would be worth it but I generally find that GPU is the one limiting performance in VR and if the GPU is not running at 100% then I’d be looking at what’s causing that first. From what you say here:
it sounds as though your GPU is not being fully utilised. Please post up your Developer Mode FPS view and a task manager screen shot showing GPU load and temperature like the one I made above.
Also, try updating to the latest nVidia drivers.
You should be getting much better FPS,especially with those settings! Try TLOD 100 (looks almost the same anyway) and 70% in OXR dev tools, then 90-100TAA.
Thanks for the long reply, I’ll test again when I’m home. But 1 question, right now I get about 22FPS with my settings above New York City (in the activities tab the explore flight). Would that be comparable to your flight? I don’t know where that was and how heavy the scenery was…
I just loaded up the NYC activity and mine starts out at 22 FPS over central park, but climbs up to 30 FPS in the minute it takes to get to the Empire State Building. This is at the settings I state above (ie. ultra/high mix and 2800 ish render res with MR off). This is a pretty tough test, so I wouldn’t take too much issue with low FPS seen here, but if your settings are much lower than mine, as you indicate above, then it is worth investigating further.
Thanks, I’ll take over your settings tonight or tomorrow and test it and post it back here. Might be that the cpu is bottlenecking after all (it can’t be the ssd or ram (32gb 3200mhz) I guess
I can’t thank you enough. I tried a lot of tweaking, but after I copied your settings I instantly got around the same FPS as you in NYC. And even better; the game looks better than ever before! It was a big surprise to me because I upgraded almost every setting so o thought this is only making it worse… but apparently setting the scaling to 80 in OpenXR does a lot of wonders (instead of ingame rendering to 70)
I also discovered how important the TLOD is; when sliding this from 200 to 400 I instantly lost about 10-15FPS so that’s basically the difference between playable and unplayable!
I’m glad I could help and that you didn’t need a CPU upgrade afterall
