Struct GpuRendererSettings 

pub struct GpuRendererSettings {
    pub power_preference: PowerPreference,
    pub clear_colour: [f64; 3],
    pub uncapped_present: bool,
}

Caller-controllable knobs for GpuRenderer::new. Defaults target “highest-performance GPU, prefer Mailbox/Immediate over vsync” — i.e. the same configuration the GPU.0 probe used to measure the FPS ceiling.

Fields

power_preference: PowerPreference

Which adapter class to request from wgpu. PowerPreference::High (the default) picks the discrete GPU on hybrid systems; PowerPreference::Low the integrated/software one. The ROXLAP_GPU_POWER=low|high env escape hatch is resolved into this field by the roxlap-render facade (QE-C6) — this crate itself reads no environment.

clear_colour: [f64; 3]

Initial clear colour cycled by GPU.1’s empty render path. The voxel-rendering substages overwrite this entirely.

uncapped_present: bool

Prefer mailbox/immediate when offered; falls back to FIFO if the surface only supports it (Wayland under Mesa often does).
