Another tip this time for anyone getting the new fps bug:
For anyone who has an ancient PC (such as myself
![Wink ;) ;)](/styles/default/xenforo/vbSmilies/Normal/wink.gif)
); since the patch there seems to be some kind of FPS bug which you have to close the game and join again to resolve. After a quick read of the forums I found this isn't necessary and you can just
go start -> run -> taskmgr. End the process called LoLClient.exe which will be happily sucking the life out of your CPU.
By doing this my average framerate went from something like 30 to 50 (or 15 to 50 when I had the bug). The downside is that you won't end up in the post game lobby chat because you've basically closed the pvp.net client.
