Description
Feature Request
I confirm:
- [] that I haven't found another request for this feature.
- [] that I have checked whether there are updates for my system available that
contain this feature already.
Description
Some old game like Commandos runs too fast on modern Linux PC.
These games often relay on empty loops to delay.
It is better to have an option to slow down the virtual CPU and make those empty loops as slow as an old, like a 486DX chip.
The option can be relative, like 1/2, 1/3, 1/10 of the host CPU speed.
I do NOT need it to be precisely some CPU chip models like 486DX100.
Justification [optional]
Wine is not designed for old games. And slow the virtual CPU down is not needed for normal windows applications.
Risks [optional]

Research direction
The issue names no files, tests, or entry points. Start by locating Proton's existing CPU-timing or game-compatibility work, then determine where a configurable relative slowdown could be integrated; done means an option can slow legacy games by ratios such as 1/2 or 1/10 and is validated with an affected game.
