I've been testing the update, and all works smoothly. A few things to note about enhanced resolution i've noticed:
If you enable enhanced resolution, the current filter you have applied will be disabled. This is probably a feature I imagine, as running a filter on top of the enhanced resolution will cause extra slowdown. It would be helpful to allow them to both be enabled if you're using high performance hardware like an Nvidia Shield or Galaxy Note 9.
Enhanced resolution will only apply to polygon based graphics. Any on-screen sprites or text will run with regular resolution and will have filters turned off. So just remember to turn off enhanced resolution if you're going to play a game like Suikoden 2, or any sprite based game, so you can use your filters (if that's your preference).
Final assessment: enhanced resolution mode looks beautiful! Crash Bandicoot, Metal Gear Solid, Tony hawk, etc, so much better and sharper!
Thanks for all your hard work Franco, and to the community members who helped as well.
