How to make CSS to lag less with more bots In non steam?

To reduce lag in CSS (Counter-Strike: Source) when using more bots in non-Steam versions, consider lowering the game's graphical settings to improve performance. Adjust the number of bots and their difficulty, as having too many high-difficulty bots can strain resources. Additionally, ensure that your system's drivers are up to date and close any unnecessary background applications that may consume CPU and memory. Finally, consider optimizing the game’s configuration files for better performance.
