Performance and trade-offs
The creator's benchmarks used Minecraft 26.2 on Fabric with Sodium and Iris, at default settings and 4 GB of memory. An Intel Core i3 11th Gen with Intel UHD Graphics reached 48 to 55 FPS at 1920×1080. An i5 12th Gen with UHD 730 managed about 36 FPS, and an i3 12th Gen with UHD Graphics 30 to 40 FPS. An i5 4th Gen with HD 4600 reached 23 to 34 FPS at 1280×720.
The feature set is still growing. Planned additions include shader grass, better rain and thunder, improved Nether, End and underwater visuals, and experimental real-time ray tracing settings. None of these ship in the 1.0 release. Pair the pack with TAA-style anti-aliasing knowledge if you want to understand the edge smoothing it uses.
