CPU slow down

CPUSLOWDOWN

Reduces a program's CPU usage by suspending and resuming all of its threads according to the specified ratio. Since the minimum timing resolution that the system can use for this operation is 1ms, (1/1000th of a second), high ratios may make the game appear choppy. This flag doesn't suspend high-priority threads.

CPU max usage

CPUMAXUSAGE

Same as CPUSLOWDOWN, but operates more selectively. This flag only suspends process threads that are consuming more CPU than the selected ratio. This option can't be set at the same time as CPUSLOWDOWN.

Ratio


Allows you to set a ratio for the slowdown used by the above flags. For example, a value of 2 will produce a ratio of 1:2, suspending the program for 1ms and then running it for 2ms, reducing that program's CPU usage by 33%.
