In game when i move my mouse my fps drops, usually i get over 100 fps so when it drops to 30 when standing still in the nexus when moving the cursor around it gets annoying. Do i need to reinstall or is this a known bug? also this is with the beta client
I'm having the same issue.
I found a fix, the problem was the wrong graphics processor was being used. you need to go to the nvidia control panel and manage 3d settings. then go to program setting (may take some time to load) and check to see if league is in the list, if it is click on it and change the preferred graphics processor to the nvidia processor. if league is not in the list you need to click add and add league to the list.
