Switch to other mod called pocket sand. I have seen users mentioning simple sidearms causes lag, probably because of incompetent code (excessive use of if statements, unnescesary conditionals or a while loop that should not be there). (-20% Consciousness: Cause->Incompetent code).

Ok thank you for the info ill check that mod out :).

@lego116 - Pocket Sand is a lite version of this with much reduced functionality - but you can easily prevent pawns auto-equipping better weapons from the mod settings under "triggers" - use best melee/ranged weapon , and you can force them to forget old weapons by right clicking the offending weapon in the sidearm's button (next to draft)

Please note the "force forget" appears to not always work for wood or some reason

I don't get it because here: https://docs.google.com/spreadsheets/d/12mAva1anZribuz6PmNoTJvTq5AdgarPyiB1cd1pFsMg/edit#gid=0 (got it from a performance modding guide on steam), they say that Pocket Sand lags and it's a great alternative

(I use Pocket Sand for now but I don't have enough pawns for the lag to be noticable)
