My brand new 2019 Macbook Pro 16" (macOS v10.15.7) suffers from severe GPU throttling after 30 minutes of playing Civilization 6. The freeze causes visual GPU artifacts that extend beyond the game's window while consuming 1100% CPU. In Windowed Mode it is sometimes possible to force-quit Civ6 and recover system stability. I've read online that these thermal issues do not occur with top-line AMD Radeon 5600M GPU.
Is there any known software fix that can prevent this catastrophic breakdown, perhaps by limiting the GPU clock's speeds?
Personally, I invested in this machine as a musician and a professional programmer to do live music and video performances, so if the GPU freezes in the middle of a concert, that will be unacceptable. Machine details:
- Machine: 2019 Macbook Pro 16"
- Processor: 2.3Ghz 8-core i9-9880H
- GPU: 8GB AMD Radeon 5500M
- View Mode: Full Screen or Windowed
- Graphics Detail: Low to Ultra. Seems to happen faster at Ultra.
- Displays: No external displays.
Suspected causes in order of likelihood:
- Flawed Thermal Design on MBP16. My machine idles at 70-85degC out-of-the-box.
- Badly applied Thermal CPU Paste at Apple's factory
- Faulty AMD Radeon 5500M drivers
- Faulty 5500M Hardware (GPU)
- A bug in Civ6. Unlikely because this should not cause visual artifacts outside of the game.
In the meantime, I am in a battle with Apple to replace my £3200 Macbook Semi-Pro.
Here is a related question, but mine should not be considered a duplicate.
