Water rendering

[ricktoberfest]

Was just reading an article about an unnamed game that put massive tessellation on everything including unrenderred water that got me thinking about the water in DCS. When my textures are slow to load in when joining a multiplayer server, the ground starts off as water. Will my water setting on HIGH be rendering that water underneath all the regular terrain that loads up on “top” of that water? Therefor having an effect on performance even if there is no visible water nearby? Or does DCS stop rendering the water underneath the ground textures?

This has been explained in the past that the way DCS does the water is the most efficient for the DCS World engine.

Any chance you have a link to that please? Searching on my phone through Tapatalk just brings up any conversation that’s mentioned water. I’d like to read up on this some more. I do remember way back there were issues with this that got fixed (maybe even before DCS world 2). I was just wondering if water settings on high had a performance impact even in Nevada where there is almost no water and being stuck at work can’t check

Generally, anything higher order in the Z-buffer (depth buffer) is not rendered. Known as Z-culling. This applies to nearly all games post-1995.

Hmm. Just for clarification I found the article again and it was about Crysis 2 putting tessellation on flat surfaces and water meshes that were underground and not rendered (possibly to give Nvidia cards an advantage as at that time they had faster tessellation than AMD did)

Was a very long time ago this was discussed. Will be difficult to find. Considering an empty mission over very basic land at the edge of NTTR, pre VR, I could get way over 120FPS no problem and I've always used high water, it's not relevant anymore. Cities steal FPS more effectively.

Yup, and if we built a proper coast and water edge, the polygon count of the maps would increase immensely, and most certainly affect how big maps could be vs performance.
