So basically I'm just wondering if my gpu is preforming as well as it should.
1080Ti Rog Strix
Ryzen 5 1600X
16 Gb ram
1440p Monitor 144Hz
It's just i noticed that when i first built the computer (a little over a year) the fps levels on eg Cs:Go were upwards of 250 most of the time and then maybe a few dips for above 200.
However over the past while the fps has gone down considerably from 250 to 150/170 at best on cs. This is across all my games. Any help is much appreciated.
If the gpu is in some way or form (however unlikely) would it be possible to get Nvidia to replace it? This is wishful thinking in terms of a worst case scenario especially since the computer is just over a year old.
