Some users have been complaining to Capcom because of the way Street Fighter 4's net code is shaping up.

Complaints from the community are mostly stemming from an interview Yoshinori Ono gave to Play Magazine that stated they won't be able to use the same net code from Super Street Fighter 2 Turbo HD Remix because the CPU and GPU use in SF4 is much higher. Having HD Remix's net code in the game would create performance issues.

Word on the street is that this would get rid of the 'rollback' effect which produces frames of animation to help eliminate perceptible lag when playing online.

Capcom manager, Seth Killian, chimed in on the Unity boards to tell people to chill about their worries that Street Fighter 4's net code won't be up to par.

It will be interesting to see how SF4's net code ends up. Anyone who's played on GGPO knows it's the best fighting game experience for online play currently out.

That said, Capcom may have something better up their sleeves, but if for some reason it doesn't work out, I certainly wouldn't mind decreasing the graphics and other things for a better online experience.
