Low FPS on Acer Nitro 5 AN515-54

MrRakso11

I have a Nitro  with the GTX 1650, I bought this laptop year and couple months ago, I used to play games such as Metal Gear 5 at 60fps, Valorant at 70fps but like a month and a half ago this games started dropping frames like crazy. Metal Gear 5 constantly runs at high 40s and Valorant is dropping to  mid 50s and high 30s when the action gets too heavy. Neither of these games are graphically demanding either so I shouldn't be experiencing this. I haven't touched any of the settings, I only play when the computer is plugged in, set to high performance, I have the nvidia control panel set to the Nvidia graphics card globally, all the game graphics are optimized via Geforce Experience. Some games still run at 60fps, such as Resident Evil 6 but that's a 9 year old game and even then it does drop to 50 sometimes. I checked the fans and everything is fine, they spin well and are clean. I've been playing on the same desk I've always been playing and I never had a problem with blocking the airvent so its cant be that either. I updated all my drivers and updated my BIOS aswell and nothing has changed. I defraged my hard drive as there's where I install all my games because the SSD is too small. 
 On the Nvidia control panel I set the Physx to the GTX 1650, maybe I should change that to integrated graphics? 
Also, I should mention that the battery doesn't last as much as it used to. But that shouldn't matter right? I always have it plugged in before playing but maybe that's affecting somehow?
Please help!!
