Portal 2 gets more DXVK Vulkan improvements with another update

By - | Views: 17,781

Valve's fantastic first-person puzzle game Portal 2 recently had a huge upgrade that pulled in DXVK giving it Vulkan support, with another update out now to further improve it.

As a reminder: this has nothing to do with Source 2. Portal 2 by default uses Direct3D 9 on Windows and OpenGL on Linux. For the Linux version, original Source engine games like this used a translation layer called ToGL to translate D3D9 to OpenGL. DXVK being added in gives the option to launch Portal 2 with "-vulkan" as a launch option which may improve overall performance.

Here's what's new in the latest update:

  - Improved Vulkan implementation
    - Overall performance improvements
    - Massively improved performance with Anti-Aliasing (MSAA) on AMD
  - Made the intro video skippable by any button on a Steam Controller
  - Added controller glpyhs to the main menu when using a controller
Bug Fixes:
  - Fixed the Super 8 teaser not playing on Linux
  - Fixed certain Unicode characters being displayed as garbage on Linux
  - Fixed text corruption in the challenge mode UI on Linux
  - Fixed a crash that could occur wrt. networking on Linux
  - Fixed the text color in advanced video settings not respecting the dark panel UI variant
  - Fixed Model/Texture detail defaulting to Low in Vulkan mode
  - Fixed the challenge mode timer being cut off
  - Fixed a crash after trying to play a demo without having the respective map
  - Fixed a crash when trying to load invalid VPKs

You can buy and play Portal 2 on Steam.

Quoting: mirvI really must find the time one day to sort out what is going wrong with DXVK on my system. Still cannot get Portal2 -vulkan to actually work, or newer DXVK versions in a system wine prefix, and I'm convinced that they are related.

I have the odd feeling that Valve will strip out the OpenGL backend and leave me unable to play it at all.

I can't speak for the portal2-bundled DXVK, but I had an issue with my system wine prefix a while back to watch out for -- especially since it's such an easy thing to miss. If it's an old prefix, be mindful that in recent years Wine started defaulting to 64-bit prefixes but as I'd been using the same prefix for years it was still 32-bit and I was trying to run a 64-bit app.

It's something about some extensions that are loaded, or the way they are loaded, or....something. Why, or how, this seemingly impacts only me I've no idea, and it's (so far) only happening with DXVK. I just need the time & motivation to follow everything through again and hunt down the exact source of the error.
There were some problems before that were fixed many package versions ago, so do need to confirm if it's still the same git commit where things no longer work for me.

I've nothing special about my setup, it's all normal, so it could just be as simple as not many are using my hardware setup, or those who it might affect aren't really using DXVK, or an old config file for all I know.
