Fps low and crash gameplay repair. For 4.21.

Since the new patch there has been reports of unusual low Fps and disconnects in the beginning of the matches. I have had this problem and thankfully figured out that my lolreplay was not compatible to the new patch which was causing problems. Make sure you exit out of lol replay or uninstall it to fix it. This may not be a solution to everyone, but it works for me and others atm.
