Details for the PC version of Final Fantasy X/X-2 HD Remaster were released during a Square Enix livestream.
According to NeoGAF, the PC version will feature dual audio options. However, choosing Japanese dialog will change the subtitles and menus as well. There does not seem to be a way to mix and match. Just like the PlayStation releases, the game will be locked to 30 FPS. Square Enix is also adding a number of graphics options, including resolution, screen mode, brightness, texture quality, anti-aliasing, and more.
The games will also feature seven in-game boosters that alter encounter rate, gameplay speed, auto-battle, the HUD, consumables, Gil, and skills.
Final Fantasy X/X-2 HD Remaster released on PC today, May 12th. The collection is also available on the PlayStation 3, PlayStation 4, and PlayStation Vita consoles as well. The collection featured the international versions of both games, which included content that had been inaccessible to North American players before.
