Hi guys!
I have problem with League of Legends, when the range indictors is enabled. But only on Windows 8.1 . In Win7 it works fine.

I'm using the display range indicators while smart casting option. If I saw my range indicators or I hover the mouse over the skills the FPS drops. I have enabled v-sync, it drop dorn from 60 to 47FPS. When I'm playing in disabled vsync, it goes down 106 from 146, so its a significant performance drop. I did everything I could: 
-restart machine for a few times 
-tried to reinstall graphics driver (AMD 14.4), even tried to install beta driver (14.6/14.7 betas. all of them)  
-quitted every other programs -> no change 
-tried windowed, borderless windowsed, full screen -> does not matter 
-set catalyst for performance -> nothing changed  
-my windows 8.1 is original, i have no pirated software

Other stange thing: when this FPS drop happens, my processor usage jump from 40-50% to 70-80%, but only on 1 core. What the hell?

Other games are working fine. (WoW,GW2,Deus EX HR, Dishonored...)

My specs:
GigaByte 970A-UD3 1.2
FX-8350 (no oc)
HyperX 1600MhZ 2x4GB CL9 (1.65V)
GigaByte 280 3GB (non-x!)
FSP Raider 550W

The temps are very good (in my opinion):
VGA: max 55C
8350: max 45C

I've already wrote to LoL support, but I think it's good if I try to solve this error/bug here too.

Same thing here Windows 8.1 on Asus N61JQ. Latest Driver for ATI Mobility Radeon HD 5730. Did not have this problem on Win7. Normal FPS in LoL for me is 60 and when i use range indicators my FPS cuts down to 20-40 witch is really bad. Also other games work fine like WoW,Borderlands 2, Dishonored, Bioshock2
