[GAMEPLAY] Frame issues until 2:00

Ever since patch 5.14, I've had strange issues with my framerate.

Though the game says I have about 80-120FPS (should be a constant 120 to begin with since I lock it there and usually have about 250FPS when unlocked), I get about two seconds worth of completely smooth, at least 80FPS movement and then my screen freezes for a fraction of a second, barely 0.1s, I would guess before it returns to a normal framerate.

Now the strangest part about this is that once I'm in lane and the minions arrive, at roughly 2:00, these issues completely disappear and my framerate goes back to a solid 120FPS.

I've tried this two times with Diana (Lunar Goddess) and once with Brand (Classic) in customs since I wanted to look at the new HUD myself. I also played ranked earlier today (Blackthorn Morgana) and don't recall having such problems, which might be related to the fact that ranked queues still have the old HUD as opposed to the new one.

I guess it's a weird bug with the new HUD (which I love, by the way) that affects framerate, but that makes me wonder why it disappears at almost exactly 2:00 into a game.

If you have any more questions you need answered to help fix this, let me know. I'll gladly assist.
