Panic Button has handled many a high-profile port for Switch, and with some astounding results. The company has been involved in projects many thought impossible for Switch, and they all required a great attention to detail. That said, it seems Panic Button's latest project was the toughest yet.
In an interview with NintendoEverything, senior producer Cody Nicewarner commented on the challenge of bringing DOOM Eternal to the Switch. You can see his full statement below.
Doom Eternal is a technically demanding title. Our starting point, with all the tricks we brought over from previous titles already in place, was comparable to how Doom (2016) ran without any optimizations. So yes I’d say it was the most difficult title to bring to the Switch.
