Xbone
Essentially, gameplay on Xbox One now appears to rely on a similar double-buffer v-sync set-up to the PS4 game, locking its frame-rate to 20fps during these lulls in performance. This means that the reading on our graph is consistently lower on patch 1.07 as compared to 1.05, where it was free to waver between 20-30fps freely. On a matching route through the bog, frame-rate can be up to 8fps slower on the latest version of the game.
PS4
With the new patch installed, the PS4 version doesn't get off lightly either. A route through the bog shows frame-rates lower than our original 1.05 test, where its lock at 20fps holds more consistently as we pass through the boggy thicket. On top of that, even traveling through simple countryside roads (or Novigrad's central city) continues to produce single-frame stutters every few seconds - a rough point we had hoped would be ironed out by now. Overall, little has improved in PS4's bid for a smooth 30fps reading here, and in fact, the tail-end of our Novigrad test shows dips to 25fps as we hit the marketplace - something not seen on the last patch.
Conclusion
So back to the question: should you install patch 1.07? Even with its negative impacts on frame-rate on PS4 and Xbox One, it's hard to overlook the wealth of positive changes to The Witcher 3. Weapon stats are rebalanced, the inventory systems are streamlined, and bug fixes too numerous to mention bolster the core package. With the new movement system, everything is snappier, with crowded pub areas now much easier to navigate. The switch to 1.07 is recommended overall, but with some reluctance: we were promised improved performance and it's surprising to see that this controversial area of The Witcher 3 actually seems to take a hit with the new update.
