### *Example Input Text:*

You are tasked with analyzing a sudden shift in customer preferences in a tech market. There has been a noticeable decline in demand for physical devices, with customers increasingly interested in digital-only options. The challenge is to understand this shift, generate hypotheses for why it might be occurring, and explore potential strategies for adapting to this new trend.

### *Processed Output with System 1 and System 2 Thinking:*

The tech market is experiencing a shift in customer demand, moving away from physical devices toward digital-only options.

[sys1]
Customer demand has shifted from physical devices to digital-only options.
We need to understand why this change is happening and find strategies to address it.
Key factors may include cost, convenience, and technological trends.
[end sys1]

[sys2]
**2.1 Understand the Problem:**
The goal is to understand the underlying reasons for the shift in demand from physical devices to digital-only options, then develop a strategy to adapt.

*Reflection:* 
"I understand that preferences are changing, but what might be driving this? Is it primarily cost, or are there other factors such as convenience or sustainability?"

*Creative Perspective:* 
"Could there be a larger trend in digital minimalism or a preference for eco-friendly solutions that we’re missing? What unseen motivations might explain this shift?"

**2.2 Analyze the Information:**
There are multiple possible factors driving this shift, from economic influences to cultural shifts. It’s essential to isolate each factor and understand its impact.

*Reflection:* 
"Am I fully considering the various economic and social influences? Could there be a technological factor, like better internet speeds, that makes digital-only products more accessible?"

*Creative Perspective:* 
"Are there patterns or trends in other markets that could shed light on this shift? Could this be part of a larger trend toward virtual experiences?"

**2.3 Generate Hypotheses:**
1. Customers prefer digital options due to lower costs. (Confidence: 0.8, Creative: 0.4)
2. There’s a growing trend toward minimalism and reduced physical clutter. (Confidence: 0.7, Creative: 0.7)
3. Digital products offer greater flexibility and ease of use. (Confidence: 0.6, Creative: 0.6)
4. Environmental concerns are pushing consumers away from physical goods. (Confidence: 0.6, Creative: 0.8)
5. Advances in tech make digital-only options more functional. (Confidence: 0.8, Creative: 0.5)
6. Pandemic-era remote work increased demand for digital solutions. (Confidence: 0.7, Creative: 0.6)
7. Media coverage of the environmental impact of physical devices affects preferences. (Confidence: 0.5, Creative: 0.7)
8. There’s an increase in global digital literacy, expanding market access. (Confidence: 0.6, Creative: 0.6)
9. Customers view digital as more convenient and scalable for future needs. (Confidence: 0.7, Creative: 0.5)
10. Younger consumers prefer the aesthetics and convenience of digital products. (Confidence: 0.6, Creative: 0.6)

*Reflection:* 
"Have I considered all possible influences? Are there any surprising factors that could explain this shift?"

*Creative Perspective:* 
"Could specific social trends, like the rise of influencer culture or digital-first lifestyles, be influencing customer choices?"

**2.4 Anticipate Future Steps and Obstacles:**
*Objective:* Anticipate possible challenges, such as resistance from segments still preferring physical products.

*Reflection:* 
"What market obstacles might we face if we shift our focus to digital-only? Are there sub-segments that still prioritize physical products?"

*Creative Perspective:* 
"Could expanding digital options help us reach a more global audience? Are there emerging trends that we could leverage in our strategy?"

[end sys2]

[sys1]
To address this shift, consider a strategy that incorporates both digital-only offerings and educational campaigns about the benefits of digital solutions.
Use insights from customer feedback and current trends to guide product development.
Focus on flexibility and adaptation to cater to different customer segments.

gfx-rs is a Rust project aiming to make graphics programming more accessible and portable, focusing on exposing a universal Vulkan-like API. It’s a single Rust API with multiple backends that implement it: Direct3D 12/11, Metal, Vulkan, and even OpenGL. We are also building a Vulkan Portability implementation (gfx-portability) based on it, which allows non-Rust applications using Vulkan to run everywhere. This post is focused on the Metal backend only.

Expanding Portability Testing

After improving functionality and performance of gfx-portability’s Metal backend through benchmarking Dota2, and verifying certain functionality through the Vulkan Conformance Test Suite (CTS), we decided to expand our testing to other projects. We were especially interested in finding projects matching the following criteria:

Open-source: allows us to easily debug issues and add or modify existing macOS window and surface support

Already using Vulkan for rendering: allows us to simply load gfx-portability on macOS in place of a Vulkan driver on other platforms, because gfx-portability implements vulkan.h

Lacking strong macOS/Metal support: potentially enables macOS users to be able to run these projects natively for the first time

Fortunately, we quickly found two projects which matched our criteria: RPCS3 and Dolphin. Similar to our experience with running Dota2 for the first time, we immediately hit some missing functionality in gfx-portability, and discovered various issues with the projects.

RPCS3

RPCS3 is an open-source Sony PlayStation 3 emulator and debugger written in C++ for Windows and Linux. RPCS3 has a Vulkan backend, and some attempts were made to support macOS previously.

The gfx-rs team started macOS integration by adding surface and swapchain support, and in the process identified a number of blockers in both gfx-rs and RPCS3. The RPCS3 developers were extremely helpful, and both teams were able to collaborate to quickly address the blockers. With the blockers addressed, we were able to render gameplay within RPCS3.

Dolphin

Dolphin is an emulator for two recent Nintendo video game consoles: the GameCube and the Wii. We noticed Dolphin was actively working on adding support for macOS, so we took the opportunity to test it with gfx-portability.

While testing Dolphin, we noticed some further minor bugs in gfx. Fortunately we were able to quickly address these issues, and soon begin to render real gameplay. The Dolphin developers have been actively working on additional improvements to support macOS and we’re excited to help this support to progress even more.

Adding Continuous Releases

For anyone wanting to try gfx-portability for themselves, we have started automatically releasing binaries under the portability repository under the GitHub latest release. We create these automatically by running continuous integration against the latest tag, which will build and upload binaries to the corresponding release. Currently we produce MacOS (Metal) and Linux (Vulkan) binaries, and plan to add Windows (Direct3D 12/11 and Vulkan) binaries soon as well.

We added these releases so users don’t have to buid gfx-portability themselves in order to test it with an existing project. The binaries are compatible with both the Vulkan loader on macOS (as a typical Installable Client Driver expected by the Vulkan loader) and by linking the binaries directly from an application (the application calls functions from vulkan.h as usual).

Conclusions

The initial focus on specific areas of CTS coverage and running Dota2 has proven to be a success. We were able to run RPCS3 and Dolphin on top of gfx-portability’s Metal backend and only had to address some minor issues in the process. As we continue to test additional real world use cases and expand CTS coverage, we expect stability and performance to continue to improve.

We gained great feedback while assisting RPCS3 and Dolphin to run well on macOS, and we look forward to helping other projects in the future as well. There are many projects only target Vulkan or OpenGL for rendering, yet would still like to be portable to other platforms, and the Vulkan Portability initiative aims to make this possible.
