Is it possible using STP on Unity6 Web?

hi im using unity 6000.28 / URP / platform target: Web
i tested STP on Windowplatform, it works well but when i switch my platfrom to web. STP doesnt work under RenderScale 1.05 , and my Gameview turn on black. can i solve it?

STP (Spatial Temporal Anti-Aliasing) requires compute shaders and thus won’t work on the web.

Even if it did it would likely severely degrade performance in web builds, like most other post fx.

STP is being investigated for WebGPU, but isn’t available yet. It will most likely never be available for WebGL due to the compute shader requirement.
