why is lol using such crap game engines and punishing them for it.. i mean i understard if i had bad hardware. but i use gaming ram a ssd hard drive and a older gtx 660 video card on a asus motherboard with quad core 3.5 ghz processor. there is no chance this is hardware issue on my end but lack of effort on their end.. never have issues with any other game ever. so why just with league what are they doing thats so different from other games ???
