Massive frame drops in CS:GO

[Moldy]

I've been having some really bad frame drops in CS:GO where it drops from 299fps all the way down to 50fps when i'm looking into smoke.I didnt have this issue just last week when when i had my old OS but i bought an SSD so i went for a fresh install but now i have these massive frame drops.BF4,WT,R2TW all work fine but CS:GO has been bugging me.I have an R9 290 with the latest 14.12 omega drivers an i5 4460 and 8GB of RAM.I have tried re-installing it multiple times (once on a new hard drive and i deleted all the old CS GO files from the other directory) but to no avail.I have also tried to verify the game cache on steam multiple times and it didnt work either.

Umm, Im going to have to guess driver issues.

I'd do a clean install of the OS then install all my drivers.
