This file targets Minecraft 1.20.1 on Fabric with Java 17. Install only this target file. The tested Oculus setup requires Connector and Forgified Fabric API. This is not a native Forge file; Oculus frame generation is blocked.

MC FSR 0.3.0 Beta

This beta adds optional AMD FSR 3.1.5 temporal upscaling. It keeps FSR 1 as the default and FSR 2.1.2 as another optional temporal method. Frame generation remains a separate option and uses AMD FidelityFX SDK 1.1.4.

Changes

• Added temporal shader support for the verified Iris and Oculus configurations on supported Minecraft versions.
• Added support for the original Complementary Reimagined r5.9.3 pack and Euphoria Patches 1.10.5. Verified effects include the default behavior, LONG_EXPOSURE modes 1 and 2, and RENKO_CUT. The pack treats LONG_EXPOSURE and RENKO_CUT as mutually exclusive.
• Added the Fabric 1.16.5 temporal shader path. Iris and Distant Horizons remain incompatible on this target.
• Kept transient TAA and jitter changes in memory. MC FSR restores the shader pack's compiled behavior when temporal upscaling is off. It does not edit pack files or save temporary setting changes.
• Preserved the settings behavior: Apply saves, Cancel and Escape discard, and Reset Defaults changes only the draft until Apply.
• Prepared separate 1.12.2 files for stock Forge and Cleanroom. Only the stock Forge file is in this CurseForge upload set. Cleanroom publication is on hold until a safe loader route is confirmed. Neither file adds temporal shader-pack or active Distant Horizons support.
• Added author metadata, an original project icon, the MC FSR MIT license, and bundled dependency notices. These release-packaging changes do not change executable code, shaders, or native libraries.

Verified scope and limits

Linux rendering checks passed for the listed configurations. On Minecraft 1.20.1, Oculus uses the Fabric file through Connector; it is not a native Forge build, and frame generation remains unsupported with Oculus. Windows DLLs build, but Windows GPU runtime behavior is untested.

Eight root Minecraft 26.3 Distant Horizons clients rendered successfully but timed out during database or world close. Clean shutdown remains unverified. No performance, latency, or frame-pacing gain is claimed. Motion data comes from the camera, not individual objects, so moving entities or shader animation can show ghosting.

The historical DeceasedCraft test ran with shaders disabled. It does not establish support for DeceasedCraft or Homestead with active shader packs.
