I find that some hard performance emulators can benefit from the resolution being lowered in order for shader enhancement quality + fps. However, if your desktop is in a higher rez and you choose in retroarch under video to put desktop to a lower rez, it never sticks on window resize.
So I would like to ask can we have a desktop rez option that can be remembered on window resize that changes the desktop rez to a custom rez when a core/specific game is loaded and reverts back to the original rez when retroarch is closed?
