I am making now small scene with island and lake water around it , so i am using this great to make water and waves. Though i’ve came to conclusion that this is really resource hungry 
What is the best way to do big water surface with your , ufna ? The shape of the island is not square , you can see that on this screenshot : ://dl.dropboxusercontent.com/s/qdlrc51bjbhgpsb/shot_140810_204117.png
So am i correct thinking that i should place blueprint patches near the edge of the land and after that make one big flat plane of water with just normals ? As even these patches i’ve placed are already dropping my FPS pretty much - i have GeForce GTX 860M , to be clear i am running BattleField 4 on full settings without AA with about 40-50 FPS.
Thanks in advance !
