(Migrated from github.com)

A #1315-styled overview of the results of trying to compile and run all examples with all sysgpu backends on Win10 64 bit.

Mach: current mach master (8ef422777...)
Zig: 0.14.0-dev.2577+271452d22
iGPU: Intel UHD Graphics 620 (i7-8550U)
dGPU: NVIDIA GeForce GTX 1050

D3D12 versions were tested with both the iGPU and dGPU. Vulkan seems to ignore the Windows GPU setting, so the tests were only done for the dGPU.

Example	D3D12	OpenGL	Vulkan	WebGPU	Metal

Explainations

❓(Metal only): Fails to compile with the following error

src\sysgpu\metal.zig:2:20: error: no module named 'objc' available within module mach
const ca = @import("objc").quartz_core;
                   ^~~~~~

src\sysgpu\metal.zig:4:21: error: no module named 'objc' available within module mach
const mtl = @import("objc").metal;
                    ^~~~~~

As Metal is iOS-only and the error is ObjectiveC-related, this might be the expected outcome.

Nothing to do here really, this error is quite clear.

glyphs

Renders one frame every ~7 seconds on the iGPU. When a frame finally renders, a message like this being written out.

B:\c-workspace\mach\zig-out\bin\d3d12\Shader@0x000002CAD1123708(14,22): warning X3578: Output value 'vertMain' is not completely initialized

App is otherwise unresponsive and has to be killed externally (^C, task manager).

(Address after the Shader@ differs between executions and programs, position after address differs between programs).

On the dGPU, the program crashes after failing to allocate a texture:

core-transparent-window

This example behaves very oddly:

The window is not transparent but has a black background
Pressing left moves the window's right edge to the left and the bottom edge upwards as if up had been pressed.
Pressing right moves the window's right edge to the right and the bottom edge upwards as if up had been pressed
Pressing up moves the window's left edge left by a couple of pixels and the window's bottom edge upwards.
Pressing down moves the window's left edge left by a couple of pixels and the bottom edge upwards as if up had been pressed twice or thrice.
Pressing down or left while the window is very small can crash the program:

I might have snipped too much of some of the stacktraces in order to not make the issue longer than it already is. Let me know and I'll provide the full trace.

A #1315-styled overview of the results of trying to compile and run all examples with all sysgpu backends on Win10 64 bit. Mach: current mach master (8ef422777...) Zig: 0.14.0-dev.2577+271452d22 iGPU: Intel UHD Graphics 620 (i7-8550U) dGPU: NVIDIA GeForce GTX 1050 D3D12 versions were tested with both the iGPU and dGPU. Vulkan seems to ignore the Windows GPU setting, so the tests were only done for the dGPU.
