ROG Zephyrus G14 help

I bought this laptop a few years ago, and so far - it’s been great. I game and work on it, and have had really no problems for the couple years I’ve had it.

I will say I’m not an expert, and think I’ve been keeping up to date on all the updates with everything, but I’m not 100% sure (I did the AMD 24.12.1 update today).

Recently though, I am having a hard time playing games. I can’t play Space Marines 2, and just overall, the laptop has become a bit slow/laggy.

I’m curious, is this because I’ve had it for awhile? Or maybe I’m missing updates?

Like I said, I’m not an expert, so I also don’t know if people usually take apart their laptop and clean it.

Sorry I’m a noob, but I appreciate your time if you respond 🫡
