Description

Since the M1 update, my MBP gets tier1/24fps reported instead of tier3/60fps

2018 MBP
32 GB 2400 MHz DDR4
Radeon Pro Vega 20 4 GB
Intel UHD Graphics 630 1536 MB

Usually runs 60fps on the main monitor, and 30fps on my external (30 Hertz)
Main monitor (higher hertz, 60fps)

{
  "fps": 24,
  "gpu": "amd radeon pro vega 20",
  "isMobile": false,
  "tier": 1,
  "type": "BENCHMARK"
}

External monitor (30 hertz, 30fps)

{
  "fps": 30,
  "gpu": "amd radeon pro vega 20",
  "isMobile": false,
  "tier": 2,
  "type": "BENCHMARK"
}

Research direction

No file, test, or entry point is named. Start by reproducing the benchmark on the listed 2018 MBP with both the 60 Hz main display and the 30 Hz external display, then trace the GPU tier and FPS classification path. Done means the reported tier and FPS match the machine's observed performance across both displays.
