(Must preface...I only downloaded the demo and played around a bit, did not even learn how to issue orders, just kept hitting 'Next Turn' so these are very preliminary remarks)
I would like to echo the requests to be able to bump up the resolution.
Movement on-screen is OK, but camera panning is choppy.
Not a fan of the look of the water...I understand the desire to have a visible representation of sea-state, but the water reminds me of 3D-Art (which I can't see)

The ships look great.
Is there a way to slow down the battle reports? I mean the little scrolls that show up and tell me the results when ships are firing at each other. They flash on and off so fast I can't get anything but a brief impression.
I hope to spend a little more time to actually learn the gameplay and I look forward to it - despite my complaints, I'm excited by this game!
Oh, my system is Athlon 3200+, ATI X800, 1 GB RAM so pump those graphics
