towor Hi there,
① Please update the graphic driver. Please go to NVIDIA official website, and download the correct driver according to your EX model and serial number. https://www.nvidia.com/en-gb/drivers/
② Please repeatedly press delete key as soon as you turn on the PC, go to BIOS. Please send us a picture of Main page, we will check if you need to update the BIOS.
③ While playing CS2, open the Task Manager (Ctrl+Shift+Esc) and go to the “Performance” tab. Check if any other processes are using a significant amount of CPU resources. If so, identify and close those processes if they’re not essential. Additionally, monitor the CPU usage of CS2 itself. If it’s consistently at 100% or close to it, there may be an issue with the game’s optimization or a conflict with other software.
