Bad news: when I played this I was using a different plugin than I am now since the last update to the emulator.

I can confirm that me text was blurry as well though. The problem is that the text is not rendered by the engine the same way the environments and characters are. You'll notice similar things in say DQVIII where the character models will be smooth and gorgeous but the faces will look terrible because they are textures that don't upscale with resolution.

That being said your shot looks really good, but if you system can handle it, turning the resolution up higher might smooth out some characters more. If you set your window size to say 1920x1080 and then set your internal resolution higher on the plugin page it will act like intense AA. I don't have a system that can handle it, but I've seen shots of people running the game with GTX590s and doing a display resolution of 1920x1200 but an internal resolution of 3840x2400 and it looks insane. I'll see if I can find some again. Really though, just crank up your internal resloution as high as you can go and still get good framerates, or alternatively just trial and error with using scaling and go as high as you can before you run into issues.

As a side note, what renderer are you using? I'm using the Direct3D11 (Hardware) renderer, so some of what I'm talking about may or may not even be relevant to you.
