Ok. Could be that the CPU working on something and the GPU is waiting for instructions. Maybe took at the possibility of throttling too. How are the temps of the components under load?
BTW I see Windows 10 in that screenshot. And the version of the driver is marked red. Is that for a reason?
Good suggestion. Though I did check and temps are within safe ranges. They’re also not at a point where throttling would start.
I guess it says Windows 10 because WINE is set to act as Windows 10. As for the driver, I assume it’s like that because it’s the Mesa driver which the game doesn’t recognise as it’s instead expecting the Windows proprietary AMD driver.
Cheers.
