The 1.03 version of The Witcher 3: Wild Hunt is now available on PS4, and it's just in time to do a first test of our own in-house framerate tool, still under very active development but hopefully good enough to give reliable results. So, there it is, a comparison between the day one patch (1.01) and today's (1.03) on PS4.
A quick explanation, each vertical white line means a new frame has been detected. Each transparent line means a frame has been duplicated. A game locked at 30 (29.97) fps would show a perfect mix of white and transparent lines. A larger white line means the game outputs (temporarily) more than 30 fps, and a larger transparent line means it's going below 30. Enjoy! :)
