There are various quotes on Eurogamer where From Software explains the difficulty they are having porting Dark Souls to PCs. "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," says producer Daisuke Uchiyama. "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." He also admits that they are not including any PC optimizations, and have not been able to overcome the framerate issues the console versions exhibited in some areas. "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," he says. "However, in exchange for that, we have prioritised adding new content for both original players and new players."
