This doesn't do anything particularly revolutionary, but it does give you a nice GUI with the ability to assign hotkeys to suspend/resume.
Useful if you want console-like game suspend to quick-switch between games, or if you're just trying to save on the electricity bill.
EDIT to add: suspended apps stay in RAM/VRAM, so be aware of your specs/game requirements if you're trying to achieve console-like "game switching". Also, could be incredibly useful for mobile gamers to save on battery/cool down the device a bit while not playing for a minute or two.
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.
Thanks for the tipp! Currently, I have a bit of a problem with hibernation. My proprietary gpu driver sends me to blackscreen and forces me to hard reboot. So that I might need to fix first. :)
Thank you for edit OP. I was wondering if this would be a good solution to trying to play 3 mins of Dark Souls while waiting for my rocket league teammates to join up. If I run two games at once my PC usually freaks the fuck out.
