# Objective
- Enable `wgpu` profiling spans
## Solution
- `wgpu` uses the `profiling` crate to add profiling span instrumentation to their code
- `profiling` offers multiple 'backends' for profiling, including `tracing`
- When the `bevy` `trace` feature is used, add the `profiling` crate with its `profile-with-tracing` feature to enable appropriate profiling spans in `wgpu` using `tracing` which fits nicely into our infrastructure
- Bump our default `tracing` subscriber filter to `wgpu=info` from `wgpu=error` so that the profiling spans are not filtered out as they are created at the `info` level.
---
## Changelog
- Added: `tracing` profiling support for `wgpu` when using bevy's `trace` feature
- Changed: The default `tracing` filter statement for `wgpu` has been changed from the `error` level to the `info` level to not filter out the wgpu profiling spans
