GregTech CE: Unofficial (GTCEu) is a 1.12.2 mod which aims to improve upon GTCE to provide the ultimate 1.12.2 GT experience.
A (very, VERY) brief list of some new features:
- Greatly improved performance and optimization from GTCE. Most users should enjoy improved RAM usage, FPS and TPS
- Fixed many GTCE bugs (invisible blocks, infinite amps)
- Improved player experience and QoL. Example: Different stone types of ores don't clog player inventories
- Completely reworked and improved fluid pipes and energy cables
- New item pipe system with huge throughputs and configurable logistics
- World generation improvements. Better performance, rebalanced ores. New virtual fluid veins for harvesting
- New content integrated from Shadows of Greg, Gregicality, GT5 Unofficial, TecTech, Nomifactory, GT New Horizons, GT IMPACT and more
- Fancy rendering effects including emissive textures and bloom
- Content added at every single tier of the game. No stone left unturned, this is a completely different GregTech experience from GTCE
And many, many, many more things...
