I have updated my nvidia drivers, comepletely uninstalled then reinstalled LoL, I ahve uninstalled pando media booster as well as Akamai netsessions, (i have read that they both are very abusive and eat bandwidth) but nothing has changed. I tried a custom game with all bots and the exact same thing happened. it ran fine for like 7 or 8 minutes, then the fps dropped to 20...then 15...8...etc...the ping spiked a few times at like 200-300 but even when the ping stayed low, the FPS never recovered. It would bounce around between 1 fps and 15 fps, SOMETIMES getting as high as 20-25. The game is unplayable. I have checked my wifi and it is fine, I did a speed test and it was fine. I ONLY have issues when playing LoL and ONLY since last patch.
