Pro's High Mode (checkerboard 4K, better textures, improved effects; capped 30fps) has framepace issues (don't you notice them?). Steady Mode (1080p; capped 30fps) and Lite Mode (1080p; uncapped, averaging between 40 and 50fps) don't have those issues, though. Even I couldn't play the High Mode because of the wonky framepacing and I'm usually absolutely not sensitive to issues like that.
Well, for people who don't like too much or can't play frentic action games and want to take time to make decision. Never tried it out, but I had a friend who beat the game like this. It's like a weird compromise to try to please fans of turn-based combat.

Yeah, that issue came after update 1.03 for some people with Overscan not disabled on their TV if I understood the issue correctly. Seems you have to enlarge the screen area in the PS4 OS menu, but yeah, it won't display other games correctly afterwards then (doesn't seem like they addressed this again in any other patch so far, so I guess this is the only temporary fix for you). Unless you instead try to turn off overscan on your TV and check if that solves it. Look for that option if your TV has it. It's often called differently for different TV brands/models. E.g. on my older Samsung TV it's under the image format/aspect ratio menu where if I choose Screen Fit it disables Overscan and shows the whole image (which makes a pretty big difference actually since otherwise your image is always zoomed in a bit and thus a bit blurrier, and you see less actual rendered image area).
