DLSS issues

[joshkbaker]

Screen effects cause some DLSS issues with the screen being cropped when using these effects. You can reproduce this by adding the Nvidia DLSS package into your project, apply 'maximum quality' or 'maximum performance' settings on the DLSS and watch the screen crop.

I think this is actually caused by the dynamic resolution feature, not specifically depending on DLSS.

Was there ever a solution for this? Really needed to use dynamic resolution but I also really like your effects.

Thanks

There is a section in the custom passes page on Unity called 'Dynamic resolution' support. It says this: "If you want to use DLSS and/or dynamic resolution on your pass, and you need to interpolate or sample UVs from color / normal or velocity, you must use the following functions to calculate the correct UVs:"

#include "Packages/com.unity.render-pipelines.high-dynamic/Runtime/ShaderLibrary/ShaderVariables.hlsl"

//...

float2 UVs = ... //the uvs coming from the interpolator
float2 correctUvs = ClampAndScaleUVForBilinearPostProcessTexture(UV); // use these uvs to sample color / normal and velocity

I have no idea how you'd implement that to your post-processing

still no solution to this issue ?

You can actually make it work with DLSS. You need to adjust injection point like this:

It works on 2022.2.16, HDRP 14.0.7.

Confirming this fixes issues on Unity 2022.3.4f1, HDRP 14.0.8. Thanks!

the problem we are not allowed to use 2022 :/ we stuck with unity 2021

I found a solution! At least for Unity 2021 and higher. Open the Glitch.hlsl file and replace _ScreenSize to _PostProcessScreenSize everywhere! That's all!
