make the game use entire CPU?

[Konk]

running the Gunslinger mod, notice that my cpu usage is super low at like 15% and the game is stuttering all over. pretty sure its only using one core, is there a way to make the game use all 8 of my cpu cores?

Run Task Manager while playing the game and when it stutters exit the game to view the CPU utilisation to confirm what cores are being used. I can't remember which game it was but I had the same issue of only one core being used despite it maxing out while the other cores were on 0% utilisation and I did something that enabled all of the cores so the utilisation was spread. I'll try to remember what I did but whatever it was it was done via Task Manager so I didn't need to change anything in the BIOS or msconfig. I seem to remember it involved enabling something and then disabling it. Possibly Affinity but not sure and don't have access to my PC to check.

Nope, the game is strictly single-threaded.
Moving to OpenXray engine can give some improvements, but the porting project is still in alpha stage.

You can always use Process Lasso to make sure the game runs on one of the performance cores. That helps with some single-thread CPU-bound games.
