Early OpenGL vs. Vulkan Linux Benchmarks With Talos Principle

[[Knuckles]]

As always, the adage applies here: make it run, make it right, make it fast.

We're halfway between steps 1 and 2

If you want to try something else to test, RetroArch has support for Vulkan already. It works with Intel's drivers, albeit with some menu bugs. They have also a libretro core that is specifically made for Vulkan.

My own short test i7-3770S, 4 GB RAM, 1080p, GTX 650 Ti 1 GB VRAM, Nvidia 355.00.27, settings: ultra, medium (modified to 2.1 mpx), medium, high.

Vulkan (64 bit): 45.8-46.9
OpenGL (64 bit): 61.6

Waiting for the profile. Btw. I packaged 355.00.27 with the SteamOS packaging, seems to work.

But does if have an auto benchmark friendly mode?

So far its looks like everyone is doing Intel benchmarks, but wasn't one of the big sells of Vulkan/Mantle to level the playing field between AMD's weak IPC vs Intel? Just wondering what things look like on say an FX-8350 or something.

You can launch it using the command line.

You can launch it using the command line.

You can launch from the CLI but I don't see anything there about replaying any automated test case, exiting gracefully, and any performance monitoring metrics.

That's really bizarre that Vulkan performance is faster than GL on windows but slower on Linux. The NVidia drivers are generally performing about the same on both.

It sounds to me like the NVidia Vulkan performance on Linux just isn't as good right now, for whatever reason. Unless someone can show that the GL performance is better under linux on this game, which seems doubtful.

Let remind the issue is the game engine itself which uses Vulkan as wrapper. Talos Principle is not yet optimized to fully use Vulkan features including multithreading. What the benchmark is measuring is only a port, it shows that Vulkan is functional.

Just press Esc to exit.

Performance monitoring, you can display fps (fps_show = "true") and also add performance counters (perfcnt_enable = "true") in the configuration file.

For automated test case, there is "demo" core using opengl 4.3.
