ConsumeSample()

void Spices::NsightPerfGPUProfilerHUD::ConsumeSample

(

)

Samples to be periodically fetched and processed by the sampler utility classes. Caveat: If this is not done, the sampler can fall into an irrecoverable state. Choose maxDecodeLatency to cover for a large-enough delay. Frame boundaries are recorded so that per-frame values, of e.g. draw call counts, can be shown as well as per-sample values.
