Many fans praised the smooth running of the event, which showcased not only the Jackal's prowess to the world, but the venue itself.
The 23,000-strong crowd sang along between bouts to the likes of Sweet Caroline, and cheered as famous faces flashed up on giant screens placed around the ground.
Fans mingled with celebs such as TV star James Nesbitt, football legend Paul Gascoigne and Ballyclare world superbike champ Jonathan Rea at the packed ground, which is home to Linfield FC and the Northern Ireland international team.
The bill also saw heavyweight Tyson Fury continue his comeback by defeating Italian Francesco Pianeta on points. The IFA said it was delighted to have been able to help home town hero Frampton realise his dream of fighting in front of his local fans at the stadium.
"There was a 23,000 capacity crowd and the fight was beamed live to more than 30 countries - it was one of the weekend's biggest sporting events anywhere in the world," the IFA said.
Worldwide visibility for the fight - and the stadium - will help keep Belfast in the running for major sporting events, it claimed.
With the SSE Arena, Kingspan Stadium, and now Windsor Park, things are looking good for the reputation of the city as a major events host.
At the same time, the IFA said it was very conscious that the ground was located in a residential area.
"It's important to us to ensure that the local residents benefit from the presence of this world-class stadium right on their doorstep," it added.
"We're looking to host future events that will be good for Belfast and for the local community."
