Modular Power Suits had to be removed as we have identified it as the cause of the increased bandwidth usage. It was added in the last update of a few days ago (Alice patch 9a) and provided higher-tier armor above IndustrialCraft 2's Quantum Armor. It easily consumed a sustained excess of 50-100 kilobytes/sec of bandwidth per player. For comparison, Minecraft usually does not hit a sustained 10-20 kilobytes/second for most areas. It used a disproportionate of CPU for the purpose of the mod. I'm afraid that we will not seeing it return at this time. If you made the items already, please post in this forum.
Can't speak for the people who liked this mod, but I am glad I will no longer have lag... Hopefully. Thanks Sk.
How does something like that even consume that much bandwidth.. seriously developers of Modular Power Suits.
