Sure.

Rendering isn't teh problem for WipEout HD. You have to note that we go
down from 1080p to 720p. Btw; 1080p > 2x720p, pixelwise. It seems like that
the problem lies within the geometry, i.e. memory bandwidth. Doubling the
frame rate cuts the bandwidth in halve with respect to a frame. That means
that the current code isn't able to deliver the same amount of geometry
within halve the time of a single frame displayed at 60fps. Possibly WipEout
HD has maxed out the (aggregative) bandwidth of the PS3. In this case only a
reduction in geometry can solve the problem. I think the game can be
optimized a little bit further, but I don't believe that they will be able to
optimize the code such that the same amount of geometry can be transfered in
halve the time, i.e. 1/120ms. If this would be possible, then one can argue
why they have wasted so many resources prior to the 3-D version, leaving as
with a game that shutters a bit on the Fury tracks. Personally, I don't
think that SL has wasted any bandwidth. The guys at SL know (knew) their
stuff and that's why we can enjoy the game in 1080p@60fps in all its glory.

SSHD does run in 720p@60fps in 3-D, but SSHD has almost no geometry when
compared to WipEout HD.

And if you ask me, I would vote for a reduction in geometry (possibly realized
as an in-game option) to be able to play WipEout HD at 720p@60fps in 3-D.

30fps? No thx.
