Phoronix: Trying The Vulkan Dota 2 & Talos Principle With Intel's Mesa Driver (July 2016)

With an Intel Broadwell ultrabook I decided to try out the latest Mesa 12.1-dev Git state with the Intel Vulkan driver to see if Dota 2 and Talos Principle are running happy yet on this open-source driver stack...

Michael must be the only one who like to benchmark broken renderers

If you like broken things, just compile mesa and llvm with -Ofast that will be the fastest

on haswell it show me a similar screen than you, the difference is that it instantly crashes

[monstercameron]

this is a bit salty but I love how Intel's driver stack isn't very good yet AMD gets all the shit.

You still haven't said if you have tried with the Steam Overlay disabled. There was some talk recently:

Something about the steam overlay recently from Plagman: https://people.freedesktop.org/~cbri...ate=2016-07-22

Anyway, The Talos Principle plays actually the same on Ivy Bridge and doesn't instantly crash. So that's maybe a Haswell specific bug. Or it depends on the settings and you have different ones.

Intel's stack is still better for me:
I can run The Talos Principle with Vulkan on my Ivy Bridge GPU, but it is buggy.
I can not run anything with Vulkan on my Southern Islands AMD GPU.

Michael, try this repo and branch:
git://people.freedesktop.org/~jekstrand/mesa wip/retroarch

Jason Ekstrand has been working with the RetroArch N64 Vulkan core (paraLLEl) developers, on which you reported recently, to get the Ivybridge/Haswell Vulkan driver into a working state. I haven't tested it with Talos Principle, but apparently it helps a lot. It does work well with paraLLEl-libretro!

1/2 OT

Michael, id Software engine developer Axel Gneiting provided Vulkan support to an open-source Quake 1 engine:

Michael, try this repo and branch:
git://people.freedesktop.org/~jekstrand/mesa wip/retroarch

On mesa master:

git merge jekstrand/wip/retroarch
Already up-to-date.

I see https://cgit.freedesktop.org/~jekstr.../anv-cts-fixes with work for passing some tests, and https://cgit.freedesktop.org/~jekstr...anv-gen7-fixes doesn't have everything merged yet, but nothing else seems relevant.
Edit: With the latter branch merged it doesn't compile.
But I haven't tried Talos for some time on Ivy Bridge, so I'll do that now.

Edit: No change, still as broken as on my first try. Maybe it's different on Gen8+.
But this time I started with lowest settings and the large glowing particles are not there and it looks "almost" working. Only on higher settings is the view almost completely obstructed.

Thanks for info.
Just tried Dota 2 with vulkan switch and overlay off on Debian sid with 12.01-3 from experimental.
Loads the game and menus work, start playing and it seems to get stuck when time to pick character, flashes to loading and pick character screen.
OpenGL no problem.

Fair enough, it wasn't merged when I tried previously. At least it's being actively worked on.
