WATCH THE NEW VERSION OF THIS ON MY CHANNEL USING SHADOWPLAY INSTEAD OF FRAPS
RECORDED @ FRAPS HALF SIZE SO VIDEO IS 720P
League of Legends running at max settings with fraps on a laptop GTX765M. Lost a 100fps due to fraps, without fraps it never drops below 80fps even in the biggest team fight. Shadows and everything are 100% maxed.

Without fraps-
Min 86fps
Max 234fps
Always 100+ except when something massive explodes on the screen like a Yasuo, Malphite and Nocturne ult all at the same times and it's still over 60fps so who cares.

Video is in 720p because I recorded it in fraps half size as I cba to wait for a 10 year upload
