Just a heads up. With the latest Nvidia graphic card driver installed (595.97) you cannot turn the "Enable HDR lighting" option off in P3D. For those of us that use the RTX Dynamic Vibrance option the HDR option has to be turned off for it to work properly. I reverted back to the previous driver (595.79) and the HDR option can be turned off again.

Edit: Forgot to mention that in order to turn off HDR in P3D you have to open the P3D cfg file and change HRD=1 to HDR=0. With the newest driver even if you have HDR=0 it will still be on in the sim.

I just loaded P3dV5 with the latest 595.97 driver with a 5070TI GPU and was able to enable and disable the HDR Lighting and the setting does change the lighting in the sim. I do not use the RTX Dynamic Vibrance option that you mentioned. What does it do? Still do not have the effects like fireworks, chimney smoke, water fountains, etc.

Very strange. I have a RTX 3080 and with HDR=0 in the P3D cfg file the HDR lighting is still on in the sim.

RTX Dynamic Vibrance is a new Nvidia feature that enhances in-game color, clarity, and contrast. It also improves visibility in darker scenes by boosting saturation. You need a GeForce RTX 20 series card or newer to use it. Think of it kind of like Envshade.

Actually it sounds more like Reshade rather than Envshade.

Envshade modifies the actual shaders of P3D itself i.e. those shader files that exist in the folder \Lockheed Martin\Prepar3D v(number)\ShadersHLSL\ 

Where as Reshade and this NVidia option exist outside of the application (P3D in the discussed instance).

In actuality I've been using Reshade for years in P3D as well as in the various games I choose to play on and off alongside P3D.

A big advantage of Reshade is that it runs outside of P3D and you can pop open the interface and modify the look and feel on the fly so to speak 😉 , also a big plus is that Reshade uses very few resources (assuming you're not trying to do anything over the top).

Reshade has a huge number of shader options, including one called Vibrance which does much the same as the NVidia version, and options like tiltshift as well as many others, you can also define custom screen shot configs.

I typically use  ~5 Reshaders with P3D v4.5 to manage the following.

• colourTemp (how warm or cold the graphics are)
• depthshading (yes, even though P3D v4/5 has no depth shading built in, it is possible to add a degree of such)
• lumaShapening (sharpens just the luma component)
• debanding (debands, used mostly for the sky)
• autoExposure (dynamically adjusting the exposure - how bright P3D looks) 

Fun fact... there is an auto exposure option built into the P3D v4.5 shaders just like in v5, however it is not enabled, I gather the dev crew didn't complete it fully within their release timelines.

The below screen pic shows a very small list of only the shaders I am currently trialing/working with, in reality there are hundreds to choose from.

Cheers
