Playing league of legends.
uncapping gives 300 fps so i cap my fps at 120 without vsync.
after 15 minutes of gameplay fpsdrops 119 and later on 118,117...
It may be a fluctuation, fps counter doesnt give much info.
what is interesting is quick close and reopening game fixes fps for 15 minutes more.
but my cpu is 49 C and gpu at 52 C at hwmonitor during game.
My all backgrouond applications are off
Background services almost off.
Ram usage is below 2 gb in game around fps drop. ive 2x2 gb 1333 hz oc ram. (9-9-9-24 to 7-7-7-20)
cpu is 1055t also oc. to 3.7 ghz
paging file is off.
prefetch off.
windows firewall off.
windows updates are off.
drivers are up to date.

to fix the issue i cleaned dust of the pc and renewed thermal paste of cpu ( which dropped cpu temps significantly but didint help to fps drop)

tried nvidiainspector profile also didint help.
as i said reconnecting game fixes issue for 15 minutes more.
thinking maybe ram is overheating but ive touched the rams they are just slightly heated. stock volt of ram was 1.5 , ive increased it 1.55 for oc.
could it be league of legends itself buggy? whats happening at 15 minutes into the game if its not heating? the ram usage of game increases but it wouldnt affect my 4gb ram at half full.

anyone have an idea?
