How to Enable and Manage Upscaling Options (DLSS, FSR2, ...) in Unity HDRP with Quality Settings?

[playerwell]

I’m working on creating a settings menu in Unity 6 with HDRP and want to include Upscale options like DLSS, FSR2, FSR, STP and TAA Upscale. However, I’m having trouble figuring out how to activate these options via code and adjust quality settings (like quality, performance …).

I can access only DLSS and FSR2 through HDAdditionalCameraData where I can allow them and set the quality to custom, but there is also has issue. When I try to disable DLSS and enable FSR2 during runtime, the whole project crashes.

To clarify, Dynamic Resolution is enabled in both the camera and settings, and DLSS, FSR2, and STP are available in the Advanced Upscalers by Priority.

I’d really appreciate it if anyone could share some example code or documentation on how to properly handle this.

My Unity version is 6000.0.29f1 (HDRP: 17.0.3)

I just did something similar the other day, to find the answer I asked Grok on X

enable FSR2 during runtime, the whole project crashes

that’s definately a bug, issue tracker ticket needed

how to activate these options via code and adjust quality settings (like quality, performance …)

Camera.main.GetComponent<HDAdditionalCameraData>().deepLearningSuperSamplingQuality = 2(Q), 1(B), 0(P), 3(UP);
Camera.main.GetComponent<HDAdditionalCameraData>().fidelityFX2SuperResolutionQuality = 0(Q), 1(B), 2(P), 3(UP);
DynamicResolutionHandler.SetDynamicResScaler(delegate () { return 66; }, DynamicResScalePolicyType.ReturnsPercentage);

Untick force screen percentage from HDRP asset settings if it’s on, and adjust min and max percentage to your needs in order this to work

How can he change the Shadow Filtering Quality at runtime? - Fix coming

Hi, We have been inform recently that we can’t change Shadow Filtering Quality at runtime in HDRP (or any other settings). After investigation and discussion we have notice that the settings wasn’t use as intented but also uncovered a kind of big oversight on the public API for HDRP asset customization. Shame on us! Users can have multiple HDRP asset included in a build with different Shadow Filtering settings and swap them at runtime. This works but isn’t very flexible since you need to swap…

Can any/all HDRenderPipelineAsset values be changed at runtime?

I have found a way to adjust the private field m_renderPipelineSettings from the Unity API. The only setting that I cannot change at runtime is raytracing, so in order to do so, I have two hdrp assets that copy each others fields at runtime, except the only difference is one asset has raytracing enabled. I have two scripts to manage this. Here is my code to accomplish all of this. 8555150–1144097–HDRPAssetConfiguring.cs (1.78 KB) 8555150–1144100–HDRPFunctionality.cs (4.16 KB) 8555150–1144103–…

Sorry for the late reply, I was busy. Thanks for the reply. I reported a bug on December 22nd but there was no progress (still open). However, I will test again after updating my Unity version

It still crashes on .29, if you post tracker link here I will vote up

My Bug Report cannot be viewed on the Issue Tracker. Currently it can only be viewed on the Unity Bug Reporting Portal and there the Status is Open and no progress
