Hello again dear community, I want to thank all the participants and the creators, the wonderful forum that you have created together, I am learning a lot from you about how to optimize my pc to the maximum so that it works as well as possible in virtual reality.
I always fly in virtual reality, I never fly in a 2d monitor.
Today by chance I have seen that in the 2d pc graphic configuration, I had the lod of the terrain and of the objects at 200, I have lowered it to 100 both and when I have re-entered the aircraft in vr, it has given me the sensation that The graphic quality was worse inside the Hp Reverb G2 and curiously the performance was worse !!!.
how can it be possible???. It is possible that by touching the 2d pc configuration these changes affect the virtual reality experience without having touched anything in the virtual reality graphic configuration menu ???.
My brain and my eyes are playing tricks on me. After this feeling I have started looking for information on the internet and there are people who claim that the 2d graphic configuration affects the results of graphic quality and performance in virtual reality.
Can this be possible??? There are even people who claim that the higher the level of graphic detail is configured in 2d pc, the better performance is obtained in the graphic framerate of virtual reality.
Is this relationship between the 2d pc versus vr graphic setup true?.
Well it’s hard to measure visual changes but you can measure performance changes. I use CapFrameX to measure. Usually I’ll take a measurement, then change a setting and compare the results. That’s probably what you need to do. Set a baseline then change a PC setting and see if you can measure a change. That would tell you definitively if the PC setting affects VR.
The 2D settings are used to generate the mirror that is being displayed on your PC monitor while you are flying in VR.
I turn my PC(2D) settings down to the very lowest low-end settings so that the graphics card has to do minimal work in order to generate the mirror image. Also, I set the resolution to be monitor resolution, but I set the resolution scaling down to around 30% so that it’s generating a very low-resolution version for the mirror image, since I don’t use that when I’m flying.
I record flights to MP4 (for uploading to youtube) using a flight recorder and then play them back in 2D using Ultra settings and a higher resolution and I notice quite a difference when I forget to turn it back to low-end settings when I go back to flying in VR.
It would be nice to be able to disable the mirror image when flying in VR so we can dedicate the full power of the graphics card to VR.
Interesting, I had also been wondering about this…. I wish there was a way to save your settings so it would be easier to jump back and forth between VR and pancake (2D) modes.
Well, MSFS does have separate settings for VR (3D) and PC (2D). It would be nice to have a separate set of settings for the on-screen mirror, or just be able to turn it off.
I tried turning the monitor off after going to VR and that went ok. Turning it back on caused a CTD. I also run the monitor at very low settings knowing the GPU can only pump a finite number of pixels
I believe the double eye image on 2d display (in Reverb G2 case) is taken from the VR rendering pipeline and is not dependent at all on the 2D display settings in the sim.
I understand from your words friend that when you forget to lower the resolution from ultra to low resolution in pc vr 2d, the performance is actually worse for you, right ???, sorry for the clarification, my native language is not English.
Guys, I tested it as I suggested to @predator038 and this is why we need to measure things. You can see below I set the LOD to it’s lowest values for both terrain and objects and it’s highest values in the PC section, so 400/200 vs 10/10. There’s no difference and I didn’t see any difference in visual quality either. Sorry but this is the data. Nothing happens in VR when changing the PC LOD values.
Please note that this is in SU8 beta and are measured for 2 minutes of flight in a Diamond DA40 using my Reverb G2.
