The first time around performance was perfect. No slowdowns, no bugs, no nothing. Firewatch is a silky smooth experience with absolutely nothing holding it back. I played a second time around to screw around with it, but only managed to discover one oversight. In the game you can pick up and collect a few things - they'll then remain in your tower the next time you visit or a new day starts. Near the beginning of the game you come across a stereo, which I decided to take on my travels to see how far I could take it. 99% of the time everything I pick up ends up stored in my tower with its own spot, as if Campo Santo programmed this in. Unfortunately the stereo didn't remain anywhere. To be honest, this is seriously nit-picking, and has no effect on gameplay whatsoever. It's a perfectly designed title overall.
For reference, you can see how your GPU will perform in comparison to ours with this set of charts.
NOTE: Precisely 50% GPU usage means only one GPU was put under load on the 295x2. This may indicate a lack of multi-GPU support.
