Dynamic Refresh Rate Switching For Intel's DRM Driver

Even if it isn't G-sync, it sounds like it could be hacked into a G-sync-like capability if the display can change refresh rates fast enough.

Can any of the devs chime in and tell me what the difference is between this and the intel module parameter "lvds_downclock" ?

I was wondering if this also works with your normal monitor output.
My Full HD monitor supports a range between 56-75Hz and some also supports 24Hz.

It's a power saving feature that's been available on laptops for a long time. You can lower the refresh rate to save power by reducing the display clock if the system is idle.

I thought this is pretty new, even on windows? Since when is it available?

From what I gather, this is G-sync without that G-sync chip. Or am I wrong?
