So, I literaly just update to the new Nvidia Geforce Experience software and I origionally thought this had no effect. However, I now find that whenever I press 3 or more keys, some of the keys (usually one or two), stick in game, cusing me to move/jump randomlly without touching any of the keys. This issue does not stop when the Geforce experience program is closed, however I am 99% 100% sure this is the issue.

TL;DR-
ISSUE: Keys Sticking (in game only)
CAUSE: Nvidia Geforce Experience program (Version 3 and Up)
TEMPORARY SOLUTION: Don't update to the new version, but if you have, end all Nvidia Process via Command Prompt and close the program via the notification tray.
PERMINANT SOLUTION: Unknown

UPDATE:
After a few minutes of extra digging (less time than I anticipated), I have found that, by ending all the processes started by the Nvidia Geforce Experience, the problem seems to no longer occur.
