Cs2 is simply not playeable

I recently began playing CS2, having logged less than 20 hours, on my brand new Legion 5i with an i7-14700HX processor and RTX 5060 graphics card. Initially, the gameplay was smooth, with settings on high at 1600p and frame rates ranging between 200-250. However, I encountered a significant issue as the game began to perform poorly, yielding unplayable frame rates such as 11, 15, and 30. In an attempt to resolve this, I tried various solutions, including uninstalling and reinstalling the game and even resetting the laptop, suspecting potential malware as the cause. Fortunately, after the reset, the game became playable once again, but this improvement was short-lived as the previous issues resurfaced. Could anyone provide assistance regarding this matter?
