Odds are they’re using an RTG to power it anyways. Titan actually has a much thicker atmosphere than even earth and it’s much farther away from the sun as well so solar isn’t going to be a good option to power anything they send down.
People always go on and on about framerate but I’d take 4k at 60fps over 1080p at 144fps any day. I never really noticed a differance over 60fps. But the resolution makes a massive difference.
Look at what they just did for the new D2R ladder season. There were literally no patches at all. They just reset the ladder. It’s not like there are any glaring problems cough cough mosiac cough cough that need to be fixed or anything.
