BPlus is good, but as you've identified, you can't set 60Hz and you can't tell the user to go into Display Properties in Windows and change it either just for your game.
Don't worry I'd never use Ceil or Floor on the maths, I only round for the drawing. What I'm saying is if you man is at position 33.1, using Ceil will put him at 32 which may be 1 pixel inside a wall or whatever so I prefer to use my rounding method. Rather than calling that function it can be inlined for speed instead such as DrawImage(whatever, Floor(x#+0.5), Floor(y#+0.5) and as DrawImage should really be part of a function that draws all your sprites, you should only need to type it once!
