Mine doesn't get these UPS spikes after latest patch - did not use py just a bunch of other mods - just no way adding as many stuff but did have a UPS drop - I notice it since I use a CPU limiter early on when it doesnt req as much so I notice these minor things early on.
The spike happens fast, but it went from ~0.17 to 0.09 whenever it spikes - prob when it runs through stuff on x tick, much better concidering its a fresh map
