Need some helps with my FPS, I've noticed it slowly dropping over recent patches and haven't found a fix. I've tried a ton of guides from multiple different sources and nothing seems to be helping. usually sit around 50-250 while nothing is happening and in team fights it can drop to below 15 and usually results in my death.
Intel Core i5 2.8ghz
16gb of RAM
Nvidia Geforce 960 2gb GPU
x2 500 GB HDD
Gigabyte motherboard (Not sure of the name)
800W corsair PSU
In game settings:
All very high except no V-sync, character inking and anti aliasing.
Nvidia settings are all default, all drivers up to date (Version 375.70).
GPU isn't overheating/Not spitting out hot air, same with all other hardware. 0 dust on any of the fans.
I've tried everything up to the point of reinstalling, id rather not do that as it never seems to help. Tried the Riot support guide for FPS also.
Any help would be appreciated, I should be getting way more FPS then I am and im confused as to why im not.
