I need a system for a game (I will tell in private if you tell me what kind of game).
That system should freeze 3d rendering when the window game is in background but keeping all other game functions working, (or with an hot-key)
and restore 3d rendering when the window pass in foreground (or hotkey).
I think it can be done with [url removed, login to view] injection.
Stopping directx rendering should lower gpu usage around 0%.
Please bid only if you know what you have to do.
