"To be completely honest, we're having a tough time doing it due to our lack of experience and knowledge in terms of porting to PC. First we thought it would be a breeze, but it's turned out not to be the case. We're still developing right now - we're crunching right now.
"In Japan there's not much of a PC market and we haven't really taken into consideration that audience before. That's one of the reasons why we haven't been able to step up on the PC platform until now."
Uchiyama went on to confirm that it hasn't fixed the frame rate problems that had hobbled certain parts of the game on consoles.
"In terms of the frame rate for say, Blighttown, From Software sincerely apologises for that happening [in the console version]," he said.
"In terms of the PC version, the quick answer is no, [we won't be fixing the frame rate problems]. Because we wanted to get the PC version out as soon as possible, it's more strictly a port from the console version. We haven't been able to step up into doing any specific optimisation for PC.
"However, in exchange for that, we have prioritised adding new content for both original players and new players."
