TAKING SCREENSHOT AT 4K ON A 1080P MONITOR
I’m experimenting with Nvidia DSR (Dynamic Super Resolution) to output a 4k image despite my 1080p monitor in order to produce much higher quality overlays for BASIC and POTATO performance profiles.
I think this can be done on AMD GPUs too using VSR (Virtual Super Resolution) feature.
This outputs a huuuuuuuuuuge 3840x2160 PNG screenshot weighting 8,55Mb taken on a 1080p monitor:
On a side note: considering how much my setup is struggling with 4k settings, have BASIC and POTATO a reason to exist on ultra HD resolution?
My RetroArch settings:
* Settings > Video > Output > Screen Resolution 3840x2160 (120hz)
* Settings > Video > Fullscreen Mode > Windowed Fullscreen Mode ON
* Settings > Video > Fullscreen Mode > Fullscreen Width 3840
* Settings > Video > Fullscreen Mode > Fullscreen Height 2160
My Nvidia Control Panel settings:
* 3D Settings > DSR factors: 4.00x
* 3D Settings > DSR Smoothness: 0%
* Resolution > DSR > 1080p, 3840x2160, HD (4.00x)
* Resolution > Refresh rate > 120hz
