Hello guys i want to ask can i increase my fps in LoL cuz when i do the Graphics to Very High my fps is max 19-20 min 12-13 i want to know if i can do something about this i tryed with game booster v3 and nothing.... please help!!

You can try unchecking the 'Wait for vertical sync' option in your in-game video settings.

Doubt it will make a large difference, you should probably not be playing high settings if you have 20 fps. Maybe it's only me but I rather play at a stable 40 with low settings than some messy 10 fps with Highest.

Well my processor is 2.16 Ghz 3GB RAM and 128mb videocard, the problem is only in my videocard.......

Set graphics low enough so you get a stable FPS, at least 30 is recommended for good in game experience.

I set my graphics at Very Low at all things and my FPS is 19 MAX!!! WTF ?!

What resolution you use? Might be a good idea to use lower
