All games stutter (on my old PC), regardless of how demanding they are. Help!

Background: I have an old laptop (8 years old, now). I only play games in which it meets the recommended requirements for. Most of the games I play are ancient (Rome 2 Total War (2011), Skyrim (2011), Doom (2016), Hell Let Loose (2019), (FFVII Reunion (2022)). In the past it played all of these games super smoothly, even with 2K texture mods, and typically on the highest graphic settings.
The problem and failed solutions: Within the last few months I noticed jitters/stuttering every few seconds on Hell Let Loose. I originally believed it was simply due to the game's recent updates, so I lowered my graphics from ultra (which ran 75FPS for the last few years)... to high... to medium... to low... I tried recommended Nvidia settings, and tried different versions of DirectX, with no positive results. Though the overall frame rate increased, the stuttering still occurred every few seconds, making the game unplayable.
I thought it could have been some other background issue. I uninstalled most of the applications that ran in the background (anti-virus, start up applications), cleared the SSD which the games ran on of a lot of storage, and cleared some space on the NVMe that the OS runs on. No improvements.
I updated the GPU driver and made sure it was set to gaming (I did have it set for video editing). Again no improvements. I then assumed that HLL was just now incompatible in its current form with my PC. That's when I learned ALL GAMES HAVE THE EXACT SAME STUTTER. Rome 2, which has always been buttery smooth, Final Fantasy, which I put down a few months ago, but was close to finishing now slide shows every 10 seconds. Freakin' A Dance of Fire and Ice, which should run on a potato, stutters!
EVEN when performing this benchmark, the same stutter occurred throughout. Same intervals, same drops.
WHAT CHANGED AND HOW CAN I FIX IT?
Note: My PC is primarily for audio. I run Pro Tools 2021.7 (perpetual), used my PC as a Dante receiver/transmitter to record 32 track multitrack, and can mix and master extensive audio sessions without any issues at all. This is purely a gaming issue.
