Regarding the issue of turning off the small core of the CPU

Hey everyone, I bought a new CPU, i5 13600KF. Compared with my previous CPU and other hardware configurations, this hardware upgrade has brought a big leap in my experience. This way, I can use 3D Scanner and other 3D design software with ease.
 
At the same time, I will also use the new computer to play games, but recently I encountered a strange thing. I can't log in to my Red Dead Redemption 2. It always shows me that the activation failed, but I clearly logged in with my genuine game account. I have played it on other computers before and it can run normally. I saw someone on the Internet who encountered a similar situation. I heard that it was related to the multi-core design of the CPU. I need to turn off the small core to enter the game normally. Therefore, I would like to consult everyone's opinions here and how to do this.
 
Thank you very much

Remove unneeded link

Hi, welcome to BC.

Please remove the link to the 3d program.  It is not part of the issue. There fore this would be spam.  

There is enough information on the web to figure out what should be done and what others are doing.  IMHO play another game.

Windows 11 should correctly handle Performance/Efficiency cores.  Windows 10 does not.  Anyway to turn off Efficiency cores, in order to use only the Performance cores, it's going to be a setting in the BIOS - possibly under "Advanced CPU Options" or similar. This is going to vary depending on your motherboard's abilities, and the manufacturer, but some allow cores to be individually switched off, others may have a single option to disable all E cores.
