Description

JobHandleHandle to prewarming job.

Full graphics state collection warmup is only supported when SystemInfo.supportsParallelPSOCreation is true. Otherwise, behavior falls back to the legacy ShaderVariantCollection.WarmUp and 
count
restricts the maximum number of shader variants instead of shader variant permutations.
