I've only played three levels but I agree about the audio and video
stutter. Does seem wrong to release a game that routinely jerks, the
sound breaks up, and the frame rate slows down (and I am convinced it's
not my pc at fault - so there!!). But aside from that, I have liked
what I have played so far. Graphics are fantastic. Perhaps Valve can
release a deluxe version which plays smoother - be it with reduced
polygon detail to remove the slow frame rate and uneven left right
movement, or a version which is identical to the current one in detail
but with the bugs removed.
I think Half Life 2 - the deluxe version, available as a large Steam
download would solve all the problems. :) Perhaps Valve is working on
it.
