I'm so grateful for this low res scaling feature!
I'm making a native 1280x720 game quite heavy on GPU, and now it runs so well even on old machines.
I now have two profiles linked to global vars:
1 - 1280x720 scaled to supercrisp full HD
2- and the "low res" profile including the new scaling method + a full screen sharpen (20%) shader activated only for this mode.
Even on a full HD monitor, the result is not that blurry!
THX, THX, THX to the C2 team for this one!
