So up until recently League had run flawlessly on my computer. Highest graphics, no hitches, delays or anything of the sort. However recently that's all gone down the shitter. Spells will take almost a second to show up on my screen. They'll have happened, but the game's reaction, visibly, will be delayed by up to a whole second. People have been able to walk from the bushes into my mid lane without them appearing until they're on top of me.
I've turned down the graphics to literally as low as it will go, even frame capping, but nothing seems to work! League also seems to be the only game I'm having this problem on.
Anyone got any ideas what's happening to me?
