Nah I'm fine, the game works fine as it is. Considering the amount of vns I have installed it'd be more of a hassle than it's worth trying that.
Some of the options are pretty obvious, like changing window size (there doesn't seem to be in-game option?)(default 1280x720, changed it to 1600x900), scaling (default bilinear, changed to anisotropic) and a few others. Some on the other hand like those involving the graphics card I'd rather not touch lest I know how to reset if something goes horribly wrong...
