Same here I can't seem to find them either.

Just bumping this as they seem to be missing still

It is not an issue but part of the overhaul. Your Yield comes from crusher (+50%) and purifier (+another 50% for a total of 100%), speed comes with scaling up your base (more blocks) and efficiency is basically done by upgrades in the tech tiers.

Fusion and fission has incredible amounts of output,making energy almost obsolete.

So to make this answer more clear: Industrial Overhaul removes the modules intentionally correct? That should be listed somewhere in the mod description because modules are a pretty big part of optimization for a lot of players new to IO.

I would suggest the addition of something else near the upper end to increase speed, rather than just increasing the number of modules - mostly to combat the lag that having a ton of refineries can cause (given how SE's engine works). Not sure what to propose though.
