No, it won’t help. It just suspends a task and going into sleep then won’t help. Maybe disable suspend and change to hibernation. This would work. You most likely would need to enable it first:

Powercfg /h on

On a commandline.

You can try out easily with e. G. Procexp from sysinternals (a great Taskmanager-replacement too!). You can just suspend your game and try it.
