Abilities causing lag/frame drops?
Has anyone else experienced lag or frame drops directly tied to abilities going off in game? The game will be running great, saying I'm getting around 250-300 fps with a ping of 50 ms, then I'll throw an ability and it'll just freeze for half a second, then go back to running smooth. It happens when others throw abilities too. And chain 2-3 abilities at once, I could be blind for almost 2 seconds. Team fights are almost unplayable. And the entire time I never get a drop in frame or spike in ping.
I have a good computer (Intel I7 6700, Nvidia GTX 970, 16 Gb RAM, etc) so I wouldn't think it's frame drops. But I also have decent Internet (6-7 Mbs down, 4-5 Mbs up) so I wouldn't think it's lag either. So I'm just at a loss. I thought maybe someone else knew about this and a way to fix it.
Thanks.
Also, I never post on here so I have no idea if this is on the wrong board. Sorry!
