Thank you for the quick reply! Ah okay, that's alright. The main issue that still seems to plague the steam release is that in DirectX 10 mode the game crashes after it loads ships, it is a very common issue and I was looking for a fix.
Otherwise, the "wobble" of the ocean or more like a vibration, and can be seen in this video https://www.youtube.com/watch?v=9TUkhcebdJE in the early moments between 10-50 seconds. The water vibrates quickly and I have this issue to a more severe extent, perhaps a physics issue? While it's not major it is quite distracting and doesn't seem to occur in the gameplay video you provided.
The game is running in DirectX 9.0c mode.
Thanks very much!
