UPDATE June 4th, 9:00am: After just one week on the market, the PS4 version of Ultra Street Fighter 4 has received its first patch bringing with it a host of improvements and changes designed to address complaints in the original release. Straight away, we noted that the menu system has been bumped up to a proper 60fps, making a world of difference during navigation. The patch notes mention changes to anisotropic filtering to "decrease blur" but it would appear this effect is applied only to specific stages. Namely, the training stage is now much cleaner with higher quality texture filtering that almost completely eliminates the issue. Unfortunately, this does not appear to be a global change as most other stages that we tested appear identical to our tests prior to the patch. Anti-aliasing also remains missing in action, while the low resolution transparency effects also appear unchanged.
A number of players are already putting the game through its paces and reporting a decrease in input latency. Running a quick trial on our own setup, there does appear to be a tangible decrease in latency across the board. Using the same technique detailed below, this updated version appears to reduce latency by one frame, or roughly 16ms.
The patch also addresses other issues such as disappearing projectiles, various UI issues, and Decapre's teleport animations. We can't say for sure if all of these issues have been fully corrected but we didn't encounter any missing Sonic Booms during our session, which is a good sign. That said, Decapre's Air Scramble still comes out at a different angle compared to the other versions of the game. We also noted minor issues with the audio mix with certain sound effects seemingly playing louder than they should.
At this point, version 1.02 is looking pretty good and feels more like the version we should have had at launch. Issues remain and unfortunately, the PS4 port still doesn't feel like the definitive edition we were hoping for - but at least progress is being made in improving the product.
