//Dynamic tuning changes the values of the base algorithm parameters (derived from targetIPS) to adapt, in real time, to
// different number of invocations/sec (mostly affects number of iterations to average).
// Dynamic tuning can have a slight negative effect on the behavior of the algorithm, so it's preferred to have it off.
//Currently it looks like it's around 750/sec on all systems when playing at 100% speed (50/60fps),
// and proportional to that speed otherwise.
//If changes are made to SPU2 which affects this number (but it's still the same on all systems), then just change targetIPS.
//If we find out that some systems are very different, we can turn on dynamic tuning by uncommenting the next line.

//Additional performance note: since MAX_STRETCH_AVERAGE_LEN = 128 (or any power of 2), the '%' below
//could be replaced with a faster '&'. The compiler is highly likely to do it since all the values are unsigned.
