Strange FPS issues after a Driver update - where rolling back did not fix the issue

So I am unsure as to whether this is the correct subreddit to be posting this on, but anyway here goes:

So After updating my graphics drivers to a newer version (driver version 391.24 - aimed at optimising for FFXV) I started to have some really strange issues with FPS. I first noticed this while playing FFXIV. I was getting < 30 FPS in an area where on the previous drivers i would get ~120 FPS. So at the time my reasonable first solution was to roll-back the drivers. Doing that did not help, as the game would run fine for a while, say 30 minutes up to an hour, at the original FPS. After which point the FPS would drop back down to 30, or in longer gaming sessions <10 FPS. I did also attempt to lower the graphically fidelity of the game, but that did not result in any change in the framerate.

I am having a similar occurance in PUBG as well... However, this situation is more interesting. When in the PUBG lobby, (soon after pc restart/booted up) it would run at a smooth 60 FPS, Then within an hour that would drop down below 10 FPS. However, although the lobby is having major FPS issues (again not solved by down-grading the graphics) The game itself when playing a round, runs over 80 FPS (V-synced to 60).

And having mentioned it in the previous paragraph, I have noticed that upon restarting the computer both PUBG lobby and FFXIV would run at their original FPS before this issue. However after a while of the PC being on (whether I was playing the games or not) the games would still show the same issues. I have also noticed some issues when using Google Chrome

Ultimately what is making me very curious about the whole situation, is that some games are completely unaffected. I just spent an hour and a half in Sniper Elite 4, and the game ran at a solid 60 FPS for the entire time that i was playing it. I noticed no issues in the playing of the game, or through any of the menus. The only other program/game that seems to be showing issues atm is the Unreal Engine, which was running between 10 and 20 FPS.

Hardware (The computer is intended for Game-Dev and Streaming/Video Editing along with Gaming):

• Intel i7 6700k (not oc)
• Asus ROG Strix GTX 1080 (not oc)
• Seagate Barracuda 2TB (where all the games are stored)
• 32GB of RAM

What i have tried:

• Complete clean install of the driver (in this case the more recent 391.35 Drivers) - Done by completely removing all nVidia software from the computer then downloading the driver installer from nVidia's website.
• Uninstalling nVidia HD Audio Driver and GeForce Experience (as i had seen people mentioning them as issues, and They are easily re-acquired when installing new drivers)
• Clean installs of the games I was having issues with (FFXIV and PUBG)
• Checking for windows updates
• Monitoring CPU/GPU Temps while in and out of game (never getting higher then 60°C on either)
• Monitoring Clock speeds of CPU/GPU, both of which were hitting their registered Clock/Boost speed.
• Lowering Graphics settings to their lowest setting - which didnt affect my FPS in anyway in the affected games.
• Running benchmarks (Unigene Heaven / Furmark) and finding no issues
• Running the FFXIV specific benchmark and being awarded the highest tier ("Extremely High" iirc - This was ran after closing FFXIV due to the FPS issues)

Any help would be appreicated and if you require more hardware information then please ask.
