Unfortunately not, I'm not even sure it's hitting 4k I'm running 3440x1440 (cropped on the width) but I'm still seeing more pixelation than I'd expect for 4k.. although TBH you don't notice the pixels after 5 minutes..
I'm on the same res and can't tell if it's just because of scaling or what but it almost feels like the view is zoomed in, I'm sure its probably exactly what it used to be like in fairness (maybe Red Alert is different?) but I know what you mean. Still looks awesome, it keeps the feel of the original perfectly.
Love the remastered soundtrack too
Do you know how to bring up the jukebox? I couldn't see a key binding for it, only next/previous tracks. Maybe that's another Red Alert thing.
