Description
Hi,
Since the version 2.5.1 of Scummvm, the application takes 100% of the CPU when you play to a 3D Residualvm game like Grim Fandango.
While it takes less than 20% using Residualvm.
On M1 Mac, we cannot hear it, however on Intel Mac, the fan throttles.
Best regards,
Kergariou

Thank you for the bug report.
ResidualVM used to throttle the display to 60 FPS by default, but this was lost by mistake when merging the ResidualVM and ScummVM code. I have now added that back.
With ScummVM 2.5.1 there is no throttling by default, so it will go as fast as it can, and indeed use all the CPU available. However you can limit the FPS manually by starting ScummVM on the command line with
--engine-speed=60. There is more details on https://docs.scummvm.org/en/v2.5.1/advanced_topics/command_line.html.
