Portal 2

This is a benchmark of Valve's Portal 2 game. The test profile assumes you have a Steam account and have Steam installed for the system. This automates the process of executing the game and using a standardized time demo.

This test will attempt to install the necessary game using your Steam account. If the test appears hung you may need to manually exit the Steam client.

To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark portal2.

Performance Metrics

Analyze Test Configuration:

Portal 2

Resolution: 1920 x 1080 - Renderer: OpenGL

OpenBenchmarking.org metrics for this test profile configuration based on 227 public results since 20 February 2021 with the latest data as of 12 July 2023.

Below is an overview of the generalized performance for components where there is sufficient statistically significant data based upon user-uploaded results. It is important to keep in mind particularly in the Linux/open-source space there can be vastly different OS configurations, with this overview intended to offer just general guidance as to the performance expectations.

Based on OpenBenchmarking.org data, the selected test / test configuration (Portal 2 - Resolution: 1920 x 1080 - Renderer: OpenGL) has an average run-time of 3 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.
