The PlayStation 3 is more complicated to develop on than the Xbox 360 - and it's harder to get games "running fast" as a result.
That's according to Enslaved dev Ninja Theory, which has created its new action adventure for both systems - and made PS3 exclusive Heavenly Sword.
"We have found that it's usually harder for us to get things working fast on the PS3," A Ninja Theory dev going by the name of Lusty posted on the studio's forums.
"It's a really powerful piece of kit but it's a little more complex to work with than the 360."
"So maybe there is slightly more work being done on the PS3 as we can be pretty sure that if we get it working at a decent FPS on PS3 then it's going to work on 360 too."
The rest of what Lusty had to say is much more neutral and mitigating.
"We're actively developing day to day on both PS3 & 360; we have the same number of PS3 and 360 kits in the studio. A lot of work is also done on a PC build as we don't have enough kits for everyone..."
"We've also got a load of automated tests which we run on all platforms. These are not just to find bugs but also to check on performance issues. We know that it's really important to maintain a high FPS with absolutely no slow-down or spiking and this helps us to do that."
"... all platforms get equal love."
We're sure they do Lusty, we're sure they do.
Microsoft is sure that the 360 is going to get a boost from Kinect, claiming that Kinect's launch can be bigger than that of every console in history - including Xbox 360 itself.
Enslaved is due for release in the UK next Friday (October 8).
