3D rendering is locked to 30FPS even though the UI is rendered at 60FPS. So the game will report 60FPS even though it doesn't run at 60FPS. (?)
-If you disable the in game Vsync, it cannot be forced. And the game still renders at 30FPS (?)
-It doesn't have arbitrary resolution support. (Unlike other Falcom games of the same era that have been updated) Trying to force the game to render at anything beyond 1920x1080 (Via GeDoSaTo) results in the game being cornerboxed into the upper left.
-16:9 and 4:3 resolutions supported only.
-The in game MSAA doesn't work unyou disable "Depth of Field" and "Backbuffer" for MSAA to work from in-game.
P.S: You have to set this in the advanced section of the configuration tool.
-The screen will flickering if you unchecked "Backbuffer" to fix this turn off V-Sync.

-Regardless of whether you use AA or not, there is a 1px wide line of garbage at the top of the screen in the center that can be extremely distracting.

-Closs Fade and Blur Effect parameters in advanced options become unchecked if you launch the game second time with "Depth Of Field" and "Use BackBuffer" unchecked.

-GOG version of the game don't have "memgame.txt" file in 3ddata folder for some reason.

-Ultra shadows looks a little aliased.
