Ugh this input lag is killing me! I've played with every possible configuration and gotten to the point where the game "feels" like it's playing at the normal speed, and yet the lowest slowdown rate I can get is 9%.
This wouldn't make any difference to me normally - I mean, if the game looks and feels as though it's running 60FPS, that's usually good enough for me - but it just so happens that I have developed a new-found interest in score runs, thanks to this game, and would love to take a shot at the High Score board. But the slowdown rate cap there is a very reasonable 5%. So looks like I'll be sitting that one out until there's either a patch for the input lag, or I find some other solution.
In the meantime, I'm working on ending Stage 3 with as massive a stock of lives and bombs as I can muster. If the first three stages are any indication, I have a feeling that the rest of the game is going to be like the first ten minutes of Saving Private Ryan.
