Throttle (ver 14-Nov-2021) Freeware Throttle asks your system hardware (ACPI throttling) to modify the clock speed going to your CPU, rather than using software "delay loops" or HLT instructions to slow your machine down. This method provides very smooth slowdowns without any incompatibilies with software. Throttle is not a TSR and uses no memory whatsoever. When running, no program will be able to detect it, nor modify its settings. In order for throttle to work its magic, it needs to talk directly to the chipset on your motherboard. Only certain chipsets created after 1996 can be manipulated by throttle. If the program cannot find a compatible chipset, it will simply terminate with a notice.
