Enum GpuTier 

pub enum GpuTier {
    Unknown,
    Integrated,
    EntryDiscrete,
    MidDiscrete,
    HighDiscrete,
}

Coarse performance class for default-quality selection, ordered low -> high so callers can compare with >=. Each backend maps its native signals (memory budget, discrete / integrated, Apple GPU family) onto this via classify_tier.

Variants

Unknown

Unknown hardware: the conservative default, never the top preset. Sorts lowest so a comparison-based resolver treats it as the floor.

Integrated

Integrated / low-power GPU: the lowest quality tier.

EntryDiscrete

Older or small discrete GPU, or an Apple base M-series: entry quality.

MidDiscrete

Mainstream discrete GPU, or an Apple Pro: mid quality.

HighDiscrete

Enthusiast discrete GPU, or an Apple Max / Ultra: high quality.
