Let's Discuss the New SR from my POV...

I love the new SR. It looks amazing it beautiful and the reaction to all of us in-game was hilarious as we were not expecting it. But there is one fatal problem. I run with sound off-lowered computer performance-and lowest settings on EVERYTHING. I ran with 10FPS and 99ish ping before the change. With all the new additions and changes I guess I got screwed pretty hard. I had a horrible Thresh game(he might be free but I am decent with him) and had one of the worst matches I could have for a support. I suddenly was hit with 5 FPS. over 100 Ping constant and the simple act of Qing had a slight delay. We got the push off hard because of our Irelia doing well top. But I could do almost nothing for my team. Not to mention I almost DCd 4 times because it got crazy in teammfights. So I ask: Are they going to change it more to make it potato-friendly? (a step down from toaster) Is it just the beta is why I get hard lag? OR will I not even be able to play it because of the changes? Either way, please tell me how I can make my FPS better, as I think I've tried everything. And I hope the connection to League isn't that bad in the future.
