>>90466343You're using the BetterRepack version right? The default screenshot hotkey is F11 and it'll take a higher quality version of the current image with no UI elements or anything. Though I would first press F1 to bring up the mod configuration menu, search screen and go to the Render Settings portion. Assuming you're not barely managing to run this on a potato you can upsample the images to improve them a little bit more as well.
If you're not using the betterrepack version then you've got a lot of downloading to do but a shitload more options if you do
