Question Why is my GPU performance way worse than before ?

[Annsom]

So i was benchmarking my gpu that is an rtx 3070 cuz i saw a slightly performance downgrade (like 10fps) i made a clean drivers install and tried drivers from others date like 2023 but nothing changed, until i closed everything and opened furmark to make a last check, when i started to stress my gpu i realized that my gpu performance got way more worst than before (110 fps un furmark 1080p). How can i fix that? From 1 minute to another withouth changing anything my gpu got worse for no apparent reason...

Furmark and other benchmark programs don't tell whole story and with each version change difficulty and scores with it. Your main concern is in actual games and at 1080p it's CPU and system that have most influence. Windows can get "dirty" over time and lower performance. Also check temperatures of whole system and GPU and if CPU and GPU hit their best frequency under load.
