Outspoken YouTuber John “TotalBiscuit” Bain has used his massive social media following to issue a punishing put-down of The National Gallery in London, slamming the tourism icon for having a locked frame-rate on its artworks.

During the three-hour long video, Bain takes aim at some of The National Gallery’s priceless historical artworks, dismissing Goya’s Portrait of the Duke of Wellington and Gossaert’s The Adoration of the Kings as “unacceptably slow”.

“How can anyone call this a triumph of the form? This is the worst frame-rate I’ve seen in my life,” Bain exclaims in the video. “Appalling. Absolutely appalling. ”

Bain goes on to explain how he was ejected from the Gallery by what he calls “the thought police” for pushing through a barrier and trying to open up Vincent van Gogh’s Sunflowers in an attempt to find the .ini file which keeps the frame-rate so low.

“In 2017 there is absolutely no excuse for the artwork of 1888 to be this ugly for me to look at,” he concludes.

Bain’s followers have vowed to make an exhaustive catalogue of all the art in The National Gallery which fails the “FPS Test”, distributing a list of the offending paintings and sculptures at the doorway to all visitors.
