I managed to update Windows via "Windows Update Assistant" from Microsoft's website, I've ran a 3rd benchmark with my updated OS that I will post below. I am still experiencing the same issues as above though, I do not think its Windows 10 being more demanding than Windows 7 as what I'm seeing is the exact same as it was before. There doesn't appear to be any clear culprits in my task manager, and everything is reporting fine but there's still a very noticeable amount of lag.
Primarily I've been playing Dead By Daylight and Dauntless, I always have Discord open and would normally watch Twitch while playing DBD (this would cause a slight amount of frame drops) but not while running Dauntless.
DBD I've had to run in the lowest settings since I got it and since this problem started it has been performing as though my browser we're open all the time with quick spikes slightly worse than that. I bought this game in September 2019 and it has ran acceptably until now.
Dauntless on the other hand has been giving me an unstable 40fps but reporting 59-60 in MSI after burner, I also had to run this game in the lowest settings to achieve desired fps but since this issue started i haven't seen anything smooth during game play.This is a free game and I started playing it in December 2019 this too was running acceptably until now.
I have also purchased Human Fall Flat after these problems arose and it will start degrading in performance relatively quick, which I find odd as I believe it to be the least demanding. I didn't play this before the lag but I know this shouldn't be happening as my younger brother can run it fine with his GeForce 710 (the bad one!) and a 1st gen intel cpu.
I reinstalled Left 4 Dead 2 which I used to run before I upgraded my PC in (almost) max settings with next to no issues, it is now experience a tiny amount of lag. My old PC had an i3-2100 @3.1ghz, a GeForce 210 1gb and 4gb ram @1300mhz. I can't associate this lag to the issue as I didn't play this before it started.
Overall my PC is performing worse than it was and has been since before I switched to Windows 10 and persist with the same intensity now that I do have Windows 10. The Benchmarks I've taken are all reporting fine and I have none from before the issue to compare them with but this issue wasn't present mere days ago and still exists now while attempting to do most anything I've done. If there's anything else I can do to fix this or at least properly identify it I still need help.
