Replying a bit late, I've had a crazy school week. I did everything you advised me to.
First I ran the DISM.exe and sfc /scannow. I got no output. Everything was fine there. I have ran these commands before in the past and I did get something twice that was then fixed by sfc, but not this time.
I checked for updates. None came up.
I downloaded the first driver you sent me. I have gotten that driver from the manufacturer site in the past, so I'm glad you confirmed I went to the right site. But at that time, I believe I downloaded it with all other recommended drivers. This time I only downloaded only the VGA driver without using DDU. Once done I tested some games. The sims 3 stuttered when I panned throughout the world and buildings were to be loaded. I then tried to launch my spiderman remastered game. It told me the driver I had was outdated, or a similar warning message. When I tried to play it stuttered in some parts badly, especially while zipping around through the city. I then played Control. The game currently lags when unpausing after pausing the game, there is an immediate stutter problem I always had. Also, to my eyes it seemed like the graphics are slightly blurry, hazy, rough around the edges. The driver did not fix these problems.
So then I decided to install the next driver. Again I did not use DDU. I checked spiderman and gameplay is smooth, as far as I can tell it's the way it was when I played it earlier this year and I didn't have graphics problems. I checked the Witcher 3. Smooth gameplay (only noticed one tiny stutter when entering a cutscene but think that's fine) and graphics look good as far as I can tell. I tested a couple other games briefly, Portal, Subnautica 1 and 2, metro exodus, minecraft (it reported good fps when I tested too). All fine.
I then did your changes to the sims 3 file successfully too and my graphics driver was detected. The sims 3 however is still experiencing stutters. However, I'm less worried about that. I think what I will try is apply some guides I used to get the sims 3 to be more optimized. There was a time my game ran wonderfully, and it was after applying those fixes/mods when I remember I was tired of it stuttering. I'm still not sure if these stutters are expected, since as far as I remember the very first time I booted the Sims 3 after purchasing it, it ran ok I think and maybe only started lagging over time/long save. But that was 2 years ago so my memory might be unreliable, so perhaps it did stutter a bit. But sims 3 should be hopefully fine, I will update in a few days how my attempt to fix it went.
So basically, seems like almost everything went successfully, for most of my games so I'm happy.
The game with the biggest issue however, remains to be Control. After installing the driver, I did not open the game. Instead, what I did was uninstall and reinstall the game so I could basically start from scratch with it since I was afraid maybe something fundamentally was corrupted after the number of times I fiddled with drivers earlier this year to try fix my issues. Ok so after I reinstalled the game, it loaded. I noticed that the graphics seemed better, the way they looked when I originally played, meaning high fidelity, no blur or roughness like I mentioned previously. However, when I pause and unpause the game I get that 2 second stutter before the game plays smoothly again. I played some combat in the intro section, seemed fine. Then I came to a dialogue scene, and then the game started lagging to an infuriating level. I saved a video of it. The scene moved aggravatingly slowly and not totally smoothly, but the characters spoke at a normal pace when it was their cue in the scene. Once the dialogue ended finally the gameplay was smooth again, it was weird. So something is still wrong with this game. I'm not sure if this is still a graphics driver problem.
Finally, here attached are the screenshots of my task manager, where you wanted to see the memory mainly. It's ok if my apps are shown. I don't mind. I disabled almost all unneeded apps on startup as you said. Now when I open the task manager, without opening anything else, memory is sitting at about 30-32%. Not sure if that is normal now.
