what the f-ps

I always thought I needed the highest, best, latest DLSS 4.5 presets to enjoy MSFS2024 to its fullest extent. little did I know that even a lousy RTX 4090 with an equally old fashioned Pimax Crystal can produce 90 fps,  it felt incredible so that I was wondering what's going on here, no kidding. I had never ever seen anything better than 50 fps, let alone 90 fps in VR:

here the fine print, extracted from above screenshot, again all 3 screenshots were in VR mode:

 

ok, I confess, that was with Preset K instead Preset M with the latest DLSS 4.5 and Performance Mode in MSFS 2024, but even QUALITY mode results in usually around 60 fps in my Citation GA flying under IFR today, mostly mixed ULTRA and HIGH settings. (ignore the 30 fps from Asobo in developer mode, they are just here to check game "render" resolution and upscaled VR "post" resolution). NVidia app in the heads-up top line says 60 fps. Who am I to disagree with NVidia - when they say 60 fps they mean 60 fps! 😀

for me 60 fps outweigh the slight degradation in glass cockpit clarity by far. btw: the slight fuzziness in the screenshot is from me holding the Pimax in one hand while pressing Print-Screen on the keyboard with the other. it looks much better in the cockpit than on the screenshot. I think from now on I will leave TAA and Preset M to the airline pilots.

A lousy 4090.  😆🤡

I have a 3080Ti. Wanna swap?

I have an older 3090 from my previous pc as a backup. I was thinking more of  like a 1080/2080 😀

but serious, even 60 fps with preset M feels great, these are the benefits of being a GA flyer without speed tape blurrz worries, in the middle of nowhere. at first I didn't believe the fps counter when I saw values beyond 60 up to 90 fps for the very first time ever in my Pimax. with DLSS 4.5 I can reduce game render resolution down to 50% by using Performance mode in MSFS and still enjoy great visual quality. we VR pilots without FrameGen need any extra fps  we can get. 

As a 5090 owner, I strongly disapprove this post.. 🤣

as a "virtual" 5090 owner, I apologise. but in return you should be able to see close to 100 fps in VR in similar environments, but realistically at least 60 in less demanding situations, which, if frame times (not fps, but reciprocal) are pretty constant, should be all you need.

As a 5090 owner,

you should be getting 70-80 fps with SMOOTH MOTION turned on. are you using that option in the NVidia app? you should, I only discovered that feature for me recently after playing with the new DLSS 4.5 NVidia app. I think they added that only some time last year, it went totally unnoticed for most MSFS gamers I guess. Can only use it in VR, otherwise in 2D with FrameGeneration turned on, you'll get pink flicker, but only on your 2D monitor, fortunately not in the VR headset.

What does this do in VR?

NM. I just saw the other thread dedicated to this topic. Cheers!

nothing, according to another poster.

100% fps increase (like FrameGen for VR) for me. finally smooth VR with Pimax Crystal resolution.

As a 5090 owner,

try night IFR, 1/2 mile visibility, real world weather tonight! you'll be rewarded with 100 fps in VR, if I can get 94 with my lousy RTX 4090.😀

Edited January 25Jan 25 by turbomax

With bad weather 1/2SM visibility, yeah I routinely get over 60fps too. One of the benefits of flying hardcore IFR: free extra fps...

But seriously, I treat MSFS2024 as a serious IFR practicing/training tool and cannot overstate how much it helps my real IFR flights. A big plus is SimBrief EFB integration - filing IFR within 2024 to use SayIntentions is so smooth and nice. 

I find it so extremely rewarding to land in CAT III conditions, something we could never do just with only our eyes which we usually tend to trust more than anything else, except that would end deadly in severe IFR. I enjoy the new found extreme high fps since NV 4.5 Smooth Motion, the best that has happened to me since MSFS 2024. 

check this thread and my LIGHT SHAFT comparison screen shots, need to have them OFF in low vis IFR:

LIGHT SHAFTS ULTRA

@turbomax How do you get so many FPS? What's your magic?

I am running MSFS2024:
- 7800X3D
- GeForce RTX 4090
- 32 GB DDR5 RAM
- MPG X670E Mainboard
- Pimax Crystal OG with OpenXR toolkit @ 90 Hz, Pimax Play 1.4.36
- DLSS 310.5, Preset J, "Balanced"
- Latest Nvidia drivers with Smooth Motion ON
- Win 11

That said, I think I have a very similar setup to yours (besides the RAM). In MSFS2024, I have everything on High settings (except for the clouds which are on Ultra), trees and grass are medium etc. I think there is no setting within MSFS which really costs me a lot of frames (besides the clouds, but I love them).

So there must be something outside of MSFS... Hardware Acceleration is ON, Resizable BAR is OFF... what else could have an impact? My system is not overclocked.

The Pimax Crystal OG should have a slightly better performance because of the Dynamic Foveated Rendering which the Lite does not have (although I have turned it off, because it makes the image jump a little bit in MSFS2024). I am running the headset on full resolution.

In MSFS2024, I am getting about 40 to 45 FPS (according to OpenXR's framerate counter) in a C172. Same goes to the Fenix A320, which is really smooth on performance.

Is there something I am missing? I should note that the latest Pimax Play update was rolled out to me yesterday. I was excited about their announcement regarding Smooth Motion not working which should have been fixed with this update. But I do not see a gain in FPS, but in smoothness.

I am surprised myself 😀

I was a hobby magician when I was a young boy, maybe that explains it? 

seriously, all I did is activate SMOOTH MOTION in NVidia APP with DLSS 4.5 (no Pimax Smooth Motion, OpenXR, STEAM VR  or whatever) and FOVEATED RENDERING in MSFS 2024 under VR settings with 50%.

those high 70-90 fps I only achieve in low density areas and smaller airports that I prefer instead of EGLL etc. and in IFR or night environments. otherwise 45-70 fps.

hokus pokus fidibus

 

62 fps, (Asobo fps counter does not see the SMOOTH MOTION interpolated "fake frames" but only its "real" 30 fps. Citation CJ4:

 

And finally, HAGS (Hardware Accelerated GPU Scheduling) must be turned ON in Windows Graphics settings for SMOOTH MOTION to work.

Hi

I think it's your DLSS version.  It has to be DLSS 4.5, the latest one which has only recently been released.  This is the game-changer bit.

post script - I'm probably just getting confused.  DLSS 310.5 is part of DLSS 4.5?
