Ahh, I have tested it myself! I made a copy and tested it with and without getKey->K. The one with ran slower.

Frame speed or movement speed? That's the important part.

Movement speed. I haven't developed it enough for frame speed quite yet.

I'm writing my first major Axe program and I noticed that the speed isn't much faster than BASIC. Is this because my TI-84+ is too old? :(
No it must be the way you are formatting your code. A 84+ runs at ~15MHz no matter how old it is.
Maybe
Er, no. The EOS kindly automatically reduces the CPU speed to 6 MHz before running assembly programs and applications so that any timing code runs the same. You're expected to explicitly set the CPU speed if you want to run at full speed. However, BASIC programs automatically run in fast mode.
Well true, but I was mainly talking about how his calculator is no slower then a newer one.

"getkey" has to test ALL the keys and return the one that's pressed.  Its also an OS routine, which makes it even slower.  In addition, the arrow keys repeat very slowly when held down.

getkey(KEY) only checks ONE key so its super super fast.

I changed to getkey(#) and mine runs faster also, thanks.

I'm pretty sure the reason getKey->var is so much slower is because it's interrupt based, as is TI Basic's version.
