I have just completed my run of all KH games on the PS4 (1.5+2.5, and 2.8). I had a big issue with 0.2 and Back Cover, which involves Frame Rate / Lag / Stuttering, whatever you want to call it. Sorry, I'm not a technical person so I do apologize if my use of terms is incorrect. What I experienced during 0.2 was jumpy camera movements, and slow down of frame rates during certain moments, for example when switching to Spellweaver Style Change. Another example would be if I would leave Aqua standing in one place, and rotate the camera around her with the Right Analog Stick, I would see jumpiness in the camera, it would never be fluid. Unable to complete a full rotation without some sort of jumpiness. Even just running, the camera would jump after a period of following behind Aqua during running. In terms of cut scenes, I would notice some serious dips in fluidity -- whatever you want to call it, frame rate drops or stuttering, it just looked awful. And as other people mentioned, incredibly jumpy even during the end credits scroll. While not as bad during watching Back Cover, it was certainly noticeable there as well. ... I do want to mention that I had absolutely no problems whatsoever during DDDHD. I also had no problems whatsoever on 1.5+2.5. I also want to mention that I've played other games such as Star Wars Battlefront 2 , Destiny, COD, Etc. that use modern graphics, and have never experienced anything like this. This leads me to believe this is an issue with just 0.2 and Back Cover, and not necessarily an issue with my PS4.
As far as tech specs: I am using a regular 500 GB PS4 (not a Pro or a Slim) and I bought it new a little over 2 years ago. I keep it in good condition and in a well ventilated area. My copy of the game is a disc copy. If there were any patches or anything I assume those have all been installed, because my PS4 always installs those automatically for games when they come out.
I am posting here because this forum has helped me out in the past when I posted here. Even though I've finished the game, it left me bothered and if I could ever fix the issue I may even replay it. More importantly, I'm concerned about KH3. I would not be able to enjoy KH3 if the gameplay and cutscenes are this bad....
I have done extensive research online, and while I see posts about this same issue, I have yet to find any real solutions. The one solution I have heard is to move the game to an external hard drive. I have yet to try this because I don't have an external hard drive that is compatible with the PS4. I am wondering if there are any other solutions? Is this just how the game is? Do these issues exist on the PS4 Pro, and if they don't, do I need a PS4 Pro to enjoy KH3 when it comes out?
Thank you so much for reading and replying! Hoping to figure this out one way or another!
