// Class : PStatGPUTimer
|
|
// Description : This is a special type of PStatTimer that also
|
|
// uses a timer query on the GSG to measure how long
|
|
// a task actually takes to execute on the GPU, rather
|
|
// than how long it took for the API commands to be
|
|
// queued up.
|
|
//
|
|
// This class may only be used on the draw thread.
|
|
//
|
|
// At present, it tracks both the CPU time (like a
|
|
// regular PStatTimer does) and the GPU time, which
|
|
// is recorded using a special PStatThread.
