GTA SA frame delay?

[pethl]

Can somebody explain the reasoning of Rockstar
why they implemented a frame-delay in GTA SA?
Does it have something to do with the console releases?

I use the "San Andreas FPS Increaser.exe" made by Crazy Dude for GTAStunting.net.
The default / vanilla / standard modifier is 14?
14 what?
14 milliseconds delay?
I don't know how it exactly works,
but when I set the modifier to 0 ms, GTA SA runs like a dream!

My framerate was / is always capped at 60 FPS.
Never had any (real) Hickups what so ever when playing this game,
but with 0 ms it looks silky smooth!
Without it, (vanilla setting) it tears my eyes out of my sockets!
It's really a day-night difference.
Framerate is still 60 FPS!
Whats the deal?
