The Steam Linux game benchmarking advancement that was talked about in the earlier article is help from Valve in being able to gain rights from game publishers to redistribute OpenGL game traces to use as benchmarks for newer AAA Linux games that otherwise don't support automated benchmarking. That article though went over some of the downsides in benchmarking Linux games with OpenGL traces. The Metro Redux testing advancement though was something that coincidentally also got finished up this past week.
A few days back I wrote about being able to finally get the Metro Redux game benchmarks running in an automated manner under Linux to the point that we're now able to test it with the Phoronix Test Suite. With Metro 2033 Redux and Metro Last Light Redux now running well for our testing purposes, I've carried out performance tests of these two games with twenty-two AMD Radeon and NVIDIA GeForce graphics cards on Linux. Besides looking at the normal FPS result there's also frame latency metrics, power consumption data for each of these graphics cards, performance-per-Watt metrics, and GPU thermal results. If you're wondering what graphics card works best for your needs for OpenGL 4.x Linux gaming, here's an interesting look with the Metro Redux titles that premiered on Steam for Linux back in December.
