Only saw the yeb vs SIN fight... Will watch the recorded video's later.
On an unrelated note: I'm positively surprised by the performance of Street Fighter IV PC on my rig. When I've tried recording some random TF2 moments with FRAPS, the framerate would instantly drop to half of its previous rate (essentially making 'live' recording a pain), whereas Street Fighter IV is hardly influenced by it at all. Maybe one single frame - if that - is dropped with max settings, although I did opt for a slightly lower screen resolution. I know TF2's a poorly optimized game 'n all for the time being, but I didn't expect the PC version to perform this well.
That said: I wish Capcom was smart enough to handle their online mode properly for the PC platform. It's real annoying when an online match (sometimes significantly) lags because the other guy's computer can't run the settings he selected, which in turn leads to a rather finnicky framerate for both players. Even had two - three matches earlier that ran at 15 - 20 frames a second; goes without saying that these were very painful matches... Inexcusable. And what's worse is that this would've been a non-issue if Capcom had forced players to lower their settings (for online play only) until it was certain they could've achieved a specific and, more importantly, FIXED framerate.
Other than that: great port. Definitely worth the 20 (via Steam).
