Pre-Text - I posted this a while ago on other forums like r/TechSupport but didn't get really much traction, so I'd like to try again here. The only comment I received was that it might be a Windows version problem, but I am on the most up to date version of windows, and other people I know do not have this problem.
Graphics - RTX 3070 Ram - 32GB CPU - Ryzen 5 5600x Monitors VG248 - DP 24G2W1G4 - HDMI
Games - EFT, Apex, Sandstorm Insurgency, Hunt Showdown Settings: Vsync - off, Borderless Windowed, Overall - medium
For some reason whenever I play these types of "hardware intensive" games, and I try to watch a youtube video at the same time, the video stutters a bunch and cannot consistently play anything above a 480p resolution. By stuttering i mean, sound will continue to play perfectly fine, but the images will freeze and stutter, on rare occasions the video buffer will freeze too, causing the video loading icon. Often times, after 5 or so minutes of this glitchy playback, youtube's auto resolution adjusting algorithm will bump my video quality down to 480 or even 360p, where the video will start playing like normal again.
Other types of media like music, movies from other websites, videos from other websites, etc. hardly if not ever perform the same way that youtube videos glitch out. Also when I am not playing these games, youtube works fine - can consistently load 1080p videos with no problem
Other people I know who do the same thing as me (play games while watching videos), with significantly lesser set-ups allegedly never have this issue, which makes sense because this issue makes no sense to me to begin with, or they have no idea that their resolution is being automatically lowered. I feel like my hardware is far too superior to be having this VERY NICHE level of technical issues, but it's happening and it has me stumped.
What I need help with: Understanding why my YOUTUBE ONLY videos lag/stutter/bottleneck when I play "hardware intensive" games and how to fix it
