[BUG/FEATURE] Provide Color Space, Tone Mapping, CAS Shader Strength and post-processing effects controls in VR

Nvidia has one. Tick Experimental in the game-ready settings and then you can have the overlay in the sim. Plenty of common effects to choose from. It’s almost like reshade but not as comprehensive.

Do you mean in GeForce Experience? If so, some are not using it all all because they have either no use or this is taking taking unnecessary resources.

But more importantly, adjusting brightness and/or colors via a post-processing Shader is not solving the problems I’m highlighting in this post and this has nothing to do with the subject. Please let me try explaining what is happening, I’ll let you search online the technical terms.

Just looking at the output (to keep it simple I’ll use only 1 gray value from 0 to 1): the simulator is rendering a white square spanning 5 pixels which are displaying as a gradient of grays from 0.8 to 1.2, but it is clipped to the [0,1] range for display obviously and as expected:

Source: 0.8 | 0.9 | 1.0 | 1.1 | 1.2
Output: 0.8 | 0.9 | 1.0 | 1.0 | 1.0 (clipped)

a) Applying a Shader to lower the luminosity by 0.2 from the source (in FS2020):

Source: 0.8 | 0.9 | 1.0 | 1.1 | 1.2
Output: 0.6 | 0.7 | 0.8 | 0.9 | 1.0 (pre process -0.2)
Display: 0.6 | 0.7 | 0.8 | 0.9 | 1.0 (clipped) <— no loss of signal between output and display

b) Applying a Shader to lower the luminosity by 0.2 at the output (after FS2020):

Source: 0.8 | 0.9 | 1.0 | 1.1 | 1.2
Output: 0.8 | 0.9 | 1.0 | 1.0 | 1.0 (clipped)
Display: 0.6 | 0.7 | 0.8 | 0.8 | 0.8 (post process -0.2) <— loss of signal, it is just dimming the clipped white

NB: this is a simple illustration of 1, and only 1 of the problems with post-processing this (there is more like quantization errors, color shift, etc…)

In other words:

The rendering is done in an unclipped linear space, then it is tone mapped, and then converted to a non linear sRGB color space which is clipped for display, and this is why you can’t post-process what I’ve written above otherwise I wouldn’t have requested it.

Thanks for the insight. Actually, I was hoping they’d include those options in the sim too. I remember them saying as much early on in the development process a year or so ago.

GeForce Experience is not applicable to the picture visible in the headset (at least for the Reverb G2), it affectes only the picture on the monitor.

@stekusteku - same for Samsung Odyssey and any other HMD. Same for Reshade, Nvidia Control panel - all just afect 2D Monitors. We really need a way to adjust color saturation etc. internally. All the HMD with OLED Displays, although great displays, dont do this sim justice.
Colors are over saturated in sunlight, and there is absolutely no way to adjust them.
Other sims I finally got issue solved with mods, for FS2020 such solution is missing.

Attached a pic from my Odyssey (left) and Monitor (right), just to show the (harsh) difference.

bumping for more time for others to share their comments.

Brightness is way more than natural leading to washed out colors and an overall haze effect.
Any capability to adjust color/brightness/contrast would be most welcome.

I’ve added the following to the OP

Thank you! It is unfortunate they are only considering a “brightness” slider in the VR Q&A items (where does this one come from?!?) and on top of that, as an item of priority 2…

In all honesty this is something like 3 sliders in a UI and 3 shaders “constants” to add. If they didn’t protect their shader binaries we could do ourselves like I did in the past with XP11:

Hi, I agree with you, we should have some sort of color correction control and the most important being a SHARPEN filter such as the one we can find in iRacing and ACC. The iRacing one is absolutely amazing, it literally improves your VR experience in an incredible way.
I have a G2 (LCD panels), and I find it to be the opposite for me, I am experiencing washed out colors with a lack of contrast (I understand haze atmospheric effect decontrast things, but still), especially when in a full sun light scenario.
I find, in my case, the visuals being the best at dusk or dawn, I am not super crazy about their sun light shader, I find their lighting most pleasant and pretty when in an ambient, more diffuse lighting scenario, but that’s just me.
Let’s vote for CC parameters : )

I have aRevert G1. It is way too bright in the sim, cockpit interiors are perfect, but outside, even on a very average April morning Illinois, it’s blindingly white.

I often resort to using the yellow filter “night mode” or whatever it’s called on the quest 2 to save my eyes!

Brightnesss/contrast/colour adjustments would deliver a massive improvement to picture quality for no performance loss, its probably my number one feature wish

updated the OP with more information about the chromacity primaries suggestion.

Most definetely a feature I would like to see as I fly only in VR since I got the G2. But the view from within the headsed is too bright / washed out…

Not just VR, can we have these for PC flying as well? With HDR on I can’t fly with the cockpit view because the horizon is blazing white. It thinks I’m looking at the controls and the eye adaptation just bleaches everything outside the aircraft. In the default pilot position in most of the aircraft you’ll get more interior in the shot which forces this effect, even though you want to be taking in the scenery OUTSIDE. Nothing like having to go third person outside a plane to kill the immersion! It makes VFR impossible if you want to be able to see inside and outside at the same time!

After careful consideration I have determined that this message may be in violation of the guidelines, so as a precautionary measure it has been removed.

Do we have any updates with this issue?

In the Q&A this week Asobo said they’re going to look at VR Later in the year, so there will likely be no changes any time soon for this specific area.

Really wish this was worked on. It hurts my eyes with the intensity
