The longer-term high/low stretches also show more variation with OpenGL hitting higher highs but also dipping to lower lows. The first clue is that the extreme minimum framerate for Vulkan still manages to stay above 40 FPS while OpenGL dips down to just under 30 FPS. However, as TR has been telling us for years, average FPS isn't the whole story. My Analysis: Obviously Vulkan isn't pushing the average framerate higher than OpenGL since Vulkan actually has a slightly lower average framerate. All tests are run with the game in 64-bit mode. The version of Talos Principle being tested is the latest public beta that is available as of April 23, 2016. I'm running a custom-compiled 4.5 Kernel with the 364.19 Nvidia drivers. In-game graphics settings include a display resolution of 1920x1200 with a matched 3D rendering resolution of 1920x1200, 2x anti-aliasing turned on, v-sync turned off, game is run in full screen mode.ģ. Run under Plasma desktop 5.6.3 with desktop compositing turned off prior to running the game, and Steam overlay disabled.Ģ. I ran the game's built-in benchmark in both OpenGL mode and Vulkan mode to evaluate the differences.Ī few notes about the test setup (hardware is listed in my sig.):ġ. My test subject for these benchmarks is the Talos Principle, which is running under Steam. As you can see from my sig, I'm rocking an almost 3 year old GTX-770 with 2 GB of VRAM, so I thought it might be interesting to test out Vulkan running on a non-bleeding edge card to see if there is any kind of benefit. So Nvidia has brought Vulkan out of beta in the 364.19 drivers for Linux.
