Release Notes

v0.18.0

Compare Source

Desktop OpenGL 3.3+ Support on Windows

We now support OpenGL on Windows! This brings support for a vast majority of the hardware that used to be covered by our DX11 backend. As of this writing we support OpenGL 3.3+, though there are efforts to reduce that further.

This allows us to cover the last 12 years of Intel GPUs (starting with Ivy Bridge; aka 3xxx), and the last 16 years of AMD (starting with Terascale; aka HD 2000) / NVidia GPUs (starting with Tesla; aka GeForce 8xxx).

By @​Zoxc in #​4248

Timestamp Queries Supported on Metal and OpenGL

Timestamp queries are now supported on both Metal and Desktop OpenGL. On Apple chips on Metal, they only support timestamp queries in command buffers or in the renderpass descriptor,
they do not support them inside a pass.

Metal: By @​Wumpf in #​4008
OpenGL: By @​Zoxc in #​4267

Render/Compute Pass Query Writes

Addition of the TimestampWrites type to compute and render pass descriptors to allow profiling on tilers which do not support timestamps inside passes.

Added an example to demonstrate the various kinds of timestamps.

Additionally, metal now supports timestamp queries!

By @​FL33TW00D & @​wumpf in #​3636.

Occlusion Queries

We now support binary occlusion queries! This allows you to determine if any of the draw calls within the query drew any pixels.

Use the new occlusion_query_set field on RenderPassDescriptor to give a query set that occlusion queries will write to.

let mut rpass = encoder.begin_render_pass(&wgpu::RenderPassDescriptor {
    // ...
+   occlusion_query_set: Some(&my_occlusion_query_set),
});

Within the renderpass do the following to write the occlusion query results to the query set at the given index:

rpass.begin_occlusion_query(index);
rpass.draw(...);
rpass.draw(...);
rpass.end_occlusion_query();

These are binary occlusion queries, so the result will be either 0 or an unspecified non-zero value.

Shader Improvements

// WGSL constant expressions are now supported!
const BLAH: u32 = 1u + 1u;

// `rgb10a2uint` and `bgra8unorm` can now be used as a storage image format.
var image: texture_storage_2d<rgb10a2uint, write>;
var image: texture_storage_2d<bgra8unorm, write>;

// You can now use dual source blending!
struct FragmentOutput{
    @&#8203;location(0) source1: vec4<f32>,
    @&#8203;location(0) @&#8203;second_blend_source source2: vec4<f32>,
}

// `modf`/`frexp` now return structures
let result = modf(1.5);
result.fract == 0.5;
result.whole == 1.0;

let result = frexp(1.5);
result.fract == 0.75;
result.exponent == 2i;

// `modf`/`frexp` are currently disabled on GLSL and SPIR-V input.

Shader Validation Improvements

// Cannot get pointer to a workgroup variable
fn func(p: ptr<workgroup, u32>); // ERROR

// Cannot create Inf/NaN through constant expressions
const INF: f32 = 3.40282347e+38 + 1.0; // ERROR
const NAN: f32 = 0.0 / 0.0; // ERROR

// `outerProduct` function removed

// Error on repeated or missing `@workgroup_size()`
@&#8203;workgroup_size(1) @&#8203;workgroup_size(2) // ERROR
fn compute_main() {}

// Error on repeated attributes.
fn fragment_main(@&#8203;location(0) @&#8203;location(0) location_0: f32) // ERROR

RenderPass StoreOp is now Enumeration

wgpu::Operations::store used to be an underdocumented boolean value,
causing misunderstandings of the effect of setting it to false.

The API now more closely resembles WebGPU which distinguishes between store and discard,
see WebGPU spec on GPUStoreOp.

// ...
depth_ops: Some(wgpu::Operations {
    load: wgpu::LoadOp::Clear(1.0),
-   store: false,
+   store: wgpu::StoreOp::Discard,
}),
// ...

By @​wumpf in #​4147

Instance Descriptor Settings

The instance descriptor grew two more fields: flags and gles_minor_version.

flags allow you to toggle the underlying api validation layers, debug information about shaders and objects in capture programs, and the ability to discard lables

gles_minor_version is a rather niche feature that allows you to force the GLES backend to use a specific minor version, this is useful to get ANGLE to enable more than GLES 3.0.

let instance = wgpu::Instance::new(InstanceDescriptor {
    ...
+   flags: wgpu::InstanceFlags::default()
+   gles_minor_version: wgpu::Gles3MinorVersion::Automatic,
});

gles_minor_version: By @​PJB3005 in #​3998
flags: By @​nical in #​4230

Revamped Testing Suite

Our testing harness was completely revamped and now automatically runs against all gpus in the system, shows the expected status of every test, and is tolerant to flakes.

Additionally, we have filled out our CI to now run the latest versions of WARP and Mesa. This means we can test even more features on CI than before.

By @​cwfitzgerald in #​3873

The GLES backend is now optional on macOS

The angle feature flag has to be set for the GLES backend to be enabled on Windows & macOS.
