Dolphin 16:9, widescreen "hack." (Swiss Widescreen Hack works with less bugs IIRC.)
What exactly is this Swiss Widescreen Hack? I only know of the Widescreen Hack on Dolphin's graphics settings.
On topic...this port is looking pretty rough. I mean, the original game isn't much of a looker either when you get up real close to the character models, but at least it ran at 60 fps. They should have gone the RE4 Wii Edition route, take the better looking GCN version (in this case, better framerate), and include all PS2 extras. A straight port of the technically inferior PS2 version is pretty lame.
I took some comparison shots in Dolphin just for fun. 4x Internal Resolution,16x CSAA, widescreen hack, downsampled to 720p for easy comparison. I don't have the same expectations for a PS3 port, but I'd at least like 1080p. It's not like TOS is pushing tons of polygons and effects. Whenever I revisit this game, it'll be the 60 fps GCN version on Dolphin.
And before someone asks about the weird double vision in the second screenshot, it's a graphical effect from the original GCN game that's exacerbated when rendering at a higher resolution. From the Dolphin Wiki:
Double Image
The game utilizes a blur technique as a "focus effect". During normal top-down gameplay, anything in the center of the screen is clear, but the edges are distorted and duplicated. If the camera angle moves down to the character's level, the effect becomes a distance blur. This is not a problem with Dolphin - this is an actual game effect that the developers intended and is present on console. But at the higher resolutions Dolphin is capable of it can be very annoying. To improve this, enable the Tales of Symphonia GC Custom Projection Hack. The hack isn't perfect however: it merely shifts the blur off screen during normal top-down gameplay. When the camera angle changes the effect will reappear incorrectly, affecting foreground elements like the characters.
To enable the Custom Projection Hack, right-click the game in Dolphin and click on "Properties". Check "Custom Projection Hack" and click on "Settings". Under "Presets" make sure it says "Tales of Symphonia GC". Applying it to Disc1 will also apply it to Disc2 since they share the same GameID.
Guess they removed this blur technique for the PS3 version, so it at least has that going for it. Eye textures also look better. Really miss the outlines though.
One more screenshot from the first village. The game can still look quite nice at times.
