UrbanChaos.cpp

Abstract:
|
|
|
|
The sound system (Miles) uses a very high-resolution timer: 32ms. The app
|
|
has badly designed message loop code. Instead of running everything off the
|
|
loop, they have their movie playing code interspersed with a call to
|
|
empty the queue. Unfortunately for them, the queue on NT is almost always
|
|
filled with these timer messages, so their code to keep track of how far
|
|
along their movie is gets starved.
|
|
|
|
To fix this we reduce the timer resolution.
|
|
|
|
Notes:
|
|
|
|
This is an app specific shim.
