Well, just figured I have left my video card operating at lower clock speeds on core and memory to simulate a GTX 1070, so I changed back to stock speeds, and comparing with Ultra now it is running minimum 25 FPS and 35 FPS faster, so average 30 FPS which is good. There material on the FFT still not doing much, I have added some lerp for coloring, some SSS direct into material pin (not simulated), depth fade and got 347ps/136 vs, not shabby.
Im using for now a disc shaped plane large enough to hit the horizon, with high triangle density in the middle and lower density as the radius increase, total 31K triangles. Idea is to put the plane to follow the camera next, but so far it is good.
The visual from above is quite pleasant, even very far, so visually I like it. The Tessendorf technique for the middle is great but I still don’t like for the shore. I am following up the latest work released notes from Tessendorf and other techniques applied to it, particularly to the shore, so I might have a taste of what it looks like soon.
