CC:DirectGPU

Code running on a CC: Tweaked computer can draw true RGB pixels, lines and shapes through DirectGPU, with fast drawing primitives meant to run at GPU-like speeds. Monitors are detected automatically, and arrays of up to 16×16 blocks are supported with optional resolution scaling from 0.1× to 4×. A single block reaches 164×164 pixels, or 656×656 at 4× scaling, and monitor arrays can be arranged and set up manually.

Images can be decoded from JPEG, PNG and GIF files, usually in 5 to 15 milliseconds. Repeated frames are streamed with smart compression, which the author describes as saving more than 90% of bandwidth. Clicks, drags and keyboard input are detected directly on the monitor surface, and several computers can update the same screen safely because the design is thread-safe. Larger setups raise the pixel count and bandwidth use, so they need planning.

The mod requires CC: Tweaked. It is published for Forge and Fabric on 1.20.1, and for NeoForge on 1.21.1, with recent builds across 1.20.1 and 1.21.1. The author states that Fabric and Forge versions have been discontinued because of maintenance difficulties, and NeoForge 1.21.1 is the focus of development.
