TimeBasedMovement vs FramesPerSecond (PBsnake as example)

Here PBsnake in 2 variants:

TimeBased and with SetFrameRate(15) implemented.
What is your opinion?

PBsnakeTBM.exe = PBsnake TimeBasedMovement
PBsnakeFPS.exe = PBsnake FramesPerSecond

Hi,

I think the time based movement could be better if you would use a hires timer.
'Cause EllapsedMilliseconds is updating in 15/16 milliseconds-steps.

Best regards

Right! I will make a better example at home.
With this (new) example you will see why a TBM implementation gives you a smooth look an a game like PBsnake.

Sadly hehe... I stumbled across this oddity also ( under linux its 1ms ). Under win2k also delay(1) is more like 10 ms.

Thats bad! We need a solution which is working for all supported OS.
I want port PBsnake to all supported OS versions at a later time.
