I just upgraded my GPU from a evga gtx 660 to a sapphire 7950. LoL ran perfectly on the 660 with fps at 60 solid, never dropping. My new 7950 however, is getting gpu spikes to 100% randomly and the fps drop to around 30... Idk why this is happening. Tested out the gpu with more demanding games like planetside 2 and it runs that game perfectly maxed out. Please help i want to enjoy LoL without lag!
