The game can crash when one thread clears RunTimeToPSOUsage while another thread is expecting it to contain a PSO it is registering stats for.
Thread A: calls CacheGraphicsPSO()
Thread B: calls CloseUserPipelineFileCache() (which empties RunTimeToPSOUsage )
Thread A: calls RegisterPSOStats() that expects to find the PSO in RunTimeToPSOUsage and crashes if it is not there.
Regular playthroughs, if possible, repeat start / stop a match. As per the ticket, testing is not required, general coverage from company wide playtesting is sufficient.
