I recorded some 4K 60FPS gameplay of Dissidia Opera Omnia.
This was a pain to get working, as I had to leave my computer on overnight to finish the Batch Download and after it finished, it turned out Nox can't boot this game into an actual battle for some reason, likely just an arbitrary restriction in the game itself.
However, I downloaded Bluestacks and that works for this game. I wasn't to hot on using that again because last time I used Bluestacks, it got pretty annoying and intrusive after a while, and it wasn't that fast. However, I must say, that the new Bluestacks 4.0 is actually really good. Other than ads occasionally being a thing unless you subscribe, it works really well.
Opera Omnia really benefits from being in 4K and on PC, as it's an actual 3D rendered game and not just using sprites like FE Heroes and KHUx. While those games do look nicer in 4K, they are mostly upsclaed as most of the assets are built for a 1440p resolution at most. 3D graphics scale to your native resolution that you set though, so Opera Omnia takes full advantage of that.
The game's interface works really well for PC, to the point where I think Square Enix should release this game on the Windows Store or on Steam, and give it cross-compatibility with the mobile version.
It's been a while since I played the game but I might get back into it. I might even start a second account to do a playthrough of it, like with FE Heroes.
