this mod is amazing but I can't use it even on my beefy gaming pc in bigger bases because of the tick lag

A temporary easy improvemnt would be the new fanmod
''No Bot Charging Repair Turret (Redux)'' until further fixes from the author. It gave me a significant improvment.

That doesn't fix the UPS problem...

Yeah, it just eases the pain a bit.
I honestly think the mod is dead, the author has been inactive for so long I don't dare to hope fore any improvements.
Persoanlly I just use the mod for the early game and after I reach abt 10k bots it's time to part ways.

with ''Buggies Nuclear Bots'' I rush uranium and then transition out of the turrets.
That mod also has some nice settings to adjust how broken or not it can be.

Hey guys, This has bugged me as well so I have created a fork: https://mods.factorio.com/mod/Repair_Turret_2

There is some more changes I missed about this one, some things are not fully tested but the UPS gain in my case is insane - went from about 20-30 to smooth 60 with beam paths enabled

My guy, you think I didn't get the mod on release? Bold
