What changed?
.2 - updated some mods, tweaked configs. !If you are planning to play in singleplayer, you need to combine this with the Client version. !If you need a zip archive (jars), use converters from mrpack to zip - they will recognize and archive mods. Server version = mods to speed up chunk loading, reduce memory and CPU usage, as well as optimize other logic. !There are mods that may slightly affect vanilla seed parity. If it is important for you to keep vanilla world unchanged and you want to + will be playing with vanilla generation - you will need to remove this mod, and structurelayoutoptimizer.jsonc config file. (things may change, so it's best to double-check what is written on the official mod pages) Some configs have been changed. Configs I recommend checking or adjusting FerriteCore. C2ME. Recipe Essentials (can disable the recipe book). NeoForge itself. Some mods are from other sources, so they may not update automatically. It is recommended to check after downloading the modpack whether they have been updated: Cupboard. Structure Essentials. Recipe Essentials. Highly recommend these mods, not included because they don't align with Extreme Optimization! concept and "Base" / there is a chance that their optimization has already been implemented by another mod(s) / other reasons, but may be useful: !Don't forget to check whether they are for the server or the client, or if it depends on whether you are playing in singleplayer. AllTheLeaks - Designed to fix various memory leaks from mods. TwilightForest Thread Safety Addon - Makes Twilight Forest generation thread-safe and faster. (maybe already fixed in Twilight Forest) TerraBlenderFix - Fixes a performance issue caused by how TerraBlender injects its surface rules. (maybe already fixed in TerraBlender) Client Crafting - Makes crafting UI's much more responsive through eliminating the server delay. Better chunk loading - Controls the vanilla chunkloading. Redirector - Implementation to reduce the required memory of the game. Better Fps - Render Distance - Adds a few performance improvements to increase fps. Connectivity - Solves several connection problems like Login-Timeouts, DecoderException, Packet size limits, Ghostblock issues, Payload too large and more. fix GPU memory leak - Fixes some bugs which leak resources within GPU memory. A collections (lists) of mods I have dealt with: Really Recommend, But. Don't Know. Optional. If you're looking for something interesting: superresolution. • "Dependencies" may not show all the mods.
