Yo,
I seem to be getting around 30 - 45% GPU usage on everything maxed. It jumps erratically between 70 and 40 fps and just doesn't want to settle. Lowering settings helps a bit, as it ends up reaching the 80s and 90s at times, but it still keeps making too many erratic jumps to be playable (and I did not buy a 1080 to play on low settings :^) ). Vsync actually makes it worse.
I have an R5 1600 OC'd to 3.75GHZ on stock cooler, so I'm sure I'm okay on the CPU front.
I would check if it's just the starting area acting up, but it crashes just before I get to the end so it keeps making me restart
