Enabling TAAU significantly cuts FPS

Summary:

In the latest beta preview, Using Deferred Rendering With PRIZMA Shader, enabling TAAU significantly cuts FPS. I go from 55-60 FPS to 30-45 FPS.

Settings are as follows - RD 24 Chunks. Shadow Quality - Medium. Point Light shadow - Low. Point light Quality - Ultra. Volumetric Fog - High. Reflections - Low. Resolution - 75.

Steps to Reproduce:

1. Enable Shader on Windows platform.

2. Enable Shader on REALMS server. Then enable Shared Resource Packs.

3. Load REALMS server on XB series X and enable deferred rendering. Enable Bilinear Upscaling and then try using TAAU Upscaling.

Observed Results:

Frame rate drops significantly. (59.0 - 60.1) Down to (35.0 - 36.5)
