Let's talk about FPS Drops.
Over the last patches my frames are getting to 50-60 spikes for about 0.2-0.5 secs.Im getting frames from 300 to 140 (80-100 on nexus side or hard teamfights).I saw that you get spikes most of time you trade 2 vs 2 or 1 vs 1.These spikes may not be a problem for someone who has an 144hz monitor but at 60hz it really feels.It is a big jump from 200 fps to 50.
Before saying that is my pc.There are my specs:i5 6600,gtx 950,8gb ram.
Made tons of tests,there is nothing wrong with my pc.I even cleaned it from dust,the problem is still there.I saw that im not the only one who has this problem,the boards is full of this problem,but I really hope riot will focus more on REAL PROBLEMS than on what skin they should get the next patch and what price it should be.Performance problems are #1.
