Comment on Microsoft is working to eliminate PC gaming's "compiling shaders" wait times

  Every driver update? There goes my idea to compile while the game is downloading.

  40 minutes??? Wtf?

  I have a Skylake CPU. I know if Microslop goes through with this, it’ll just be another “oh sorry, can’t run this software on your hardware. ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯ Please buy a new computer. Also SafeBoot and Intel for some reason.”

  … forty minutes?

  Good lord.

  I think the longest amount of time I’ve spent compiling shaders on a Steam Deck is for Cyberpunk 77, and it can’t have been much more than 5 minutes.

  … Either that or trying to get a Switch emulator to properly pre-compile shaders.

  But anyway: This is an unaviodable thing that has to be done when the game relies so heavily on GPU shaders.

  You have to actually generate those shaders, before you can use them, and that’s gonna be specific to your hardware.

  So what MSFT is doing here is just pre-compiling them for I guess … every game they offer, with every Nvidia GPU/driver update, and then having a cloud system that allows you to download them instead of compiling them on your end.

  So basically its kinda like downloading a game + hardware specific driver, sort of.

  Also, I… I’m not sure, but I don’t think Steam does this.

  Yeah, its indicated that shader compilation is happening in the ‘Download’ section, but so are ‘File Operations’ - aka, cleaning up loose files and doing memspace management …

  I am pretty sure you are just actually compiling the shaders on your own hardware, its just visualized to the user as a step in the ‘Download’ section, to get across the idea that the game isn’t ready to be played untill all those steps are complete.

  Or, you can change a setting somewhere, and it just skips that step so that it isn’t part of the initial ‘Download’ process, and instead occurs the first time you hit play, or, after any game/driver update that has delta’d the shader code.

    Shaders are definitely downloaded on the Steam Deck. Don’t know about other hardware though.

      pulsegeek.com/…/shader-pre-caching-on-steam-deck-…

      Ok, so, its kind of both:

      Shader pre-caching means compiling GPU programs ahead of play to avoid on-demand stalls. On Steam Deck, the path usually includes prebuilt Vulkan pipelines distributed by Steam, plus local caches created by DXVK for DirectX 9 and 11 and by VKD3D for DirectX 12. This two tier approach mitigates runtime work and smooths frame pacing when new materials or post processing effects first appear.

      …

      Caches consume storage and can become stale after game patches or driver changes. When mismatches occur, the system may recompile anyway, so the saved time diminishes.

      …

      Shader stutter often traces to pipeline state changes that force compilation or shader specialization. With Vulkan, pipeline objects encode fixed state to avoid per draw setup, which shifts cost to creation. Pre-caching amortizes that by compiling pipelines during downloads or first launches. The effect is fewer spikes, especially during initial encounters with enemies, weather transitions, or new regions. Still, certain shaders depend on runtime constants or device specific details, which can prevent perfect reuse.

      So, you may be downloading various prebuilt components, and you may be pre-caching/pre-compiling local files based off of those prebuilt components, and the game/gpu/driver.

  Not played enshrouded in a while, should play again sometime. Ideally play some coop too
