Gah, what the hell. I couldn't get it to run at a proper speed at all.
You're seriously going to write it off as unenjoyable just because of that? ![Undecided :-\](/forum/Smileys/default/undecided.gif)
It works fine for me too, and that was with GsDX (or whatever it's called) version 9xx or something. I recently updated it to 16xx. Let's just say thatI had a nother game that would chug at 4fps (yes, 4)... I can spew what my config settings are at if you like.
As for Ban, I prefer bosses over stages mostly too. I mean sometimes I can enjoy stages in a shmup. But most of the time, I find that they require most of the memorization in a shmup, which I HATE. Even in touhou, with its short stages, I still hate them. Almost half+ of my deaths and bombs are during stages, which is caused not by lack of skill or something. But out of failure to remember t hat "zomg wave of baddies that spam bullets like no tomorrow that nobody can possibly dodge easily spawns on the left side and oh shit I'm on the right *bomb*".
I do like my stages to be somewhat difficult provided they aren't trivilized by doing each and every part in it "right" however. I find stage 3 of stella vanity is a great example of this.
