Performance Metrics

Analyze Test Configuration:

APITest 2014-07-26

Resolution: 1920 x 1080 - Test: DynamicStreaming GLBufferSubData

OpenBenchmarking.org metrics for this test profile configuration based on 100 public results since 27 July 2014 with the latest data as of 28 January 2024.

Additional benchmark metrics will come after OpenBenchmarking.org has collected a sufficient data-set.

Based on OpenBenchmarking.org data, the selected test / test configuration (APITest 2014-07-26 - Resolution: 1920 x 1080 - Test: DynamicStreaming GLBufferSubData) has an average run-time of 2 minutes. By default this test profile is set to run at least 3 times but may increase if the standard deviation exceeds pre-defined defaults or other calculations deem additional runs necessary for greater statistical accuracy of the result.
