Question GPU Usage drops over time whilst gaming ?

[Aazure]

Hi all, haven't posted here in a long, long time but figured this was my last hope since I couldn't find anything else online that solved my issue.

I'm having an issue when playing MHWilds where my FPS will slowly decrease overtime as I play until it becomes a literal slideshow. It seems like this is happening because my GPU usage is actually dropping from 80% (starting) all the way to 30% over time. I've tried lowering the graphic-intense settings to see if that improves framerate, but it actually has no effect.

Since it gets worse over time, I thought it was maybe due to thermal throttling. Through HWiNFO, I was able to see that neither my GPU, CPU, or RAM had thermal throttled/hit voltage limit a single time over a 3-hour period of playing Wilds (with lag and all). Some other posts with similar issues (in different games) had noted that it was maybe caused by a bad storage drive, but CrystalDiskInfo said both my boot drive and game drive are at 99% health (M.2 NVMes). Those same posts also mentioned problems with their RAM but I'm not well-versed enough to know what to check for when looking at RAM counters. Others said it might be an issue with an abnormally large pagefile.sys allocation, but I have mine set to system managed for all drives.

Annoyingly enough, other intense games don't cause this issue. If I load into other triple-a title games, my GPU will stay at 99% for the entire session and it won't ever drop its usage and my PC will sound like a jet engine with all its fans. I'm not sure if this is an issue with Wilds itself but I haven't seen others have this exact issue I'm having. If anyone has a possible solution, it would be greatly appreciated!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

Seeing how you have an Nvidia GPU, which driver version are you on for your GPU?

Annoyingly enough, other intense games don't cause this issue.
What other titles have you taxed the system with?

Try with DDU, remove all GPU drivers(intel, AMD and Nvidia) in Safe Mode, to manually install the latest GPU driver sourced from Nvidia's support site in an elevated command, i.e, Right click installer>Run as Administrator.

My apologies, I updated the post with the full information.

I was at first using 572.83, used DDU to revert to 566.36 in an initial attempt to solve issues, and when that didn't work I used DDU again and updated to 576.02 (current).

I've played Elden Ring, Helldivers 2, ARK Survival Ascended, Jedi Fallen Order/Survivor, etc. But I guess most recently it would be ARK Survival Ascended (~10 hours in March), which still didn't have this issue.
