[Community Project] WIP Weather & Water Shader

Hi, we are using excellent project in our game and on the PC front, performance wise, everything is absolutely fine (Unreal 4.18.3 and 4.19.2). On the (original) Xbox One though - it is a different story. On 4.18 we managed to run the chapter that is using BP_ocean class to run at almost 900p at mostly steady 30FPS which at point is good enough for the original Xbox One (pre S version). Sadly, we cannot ship with 4.18 version of the engine and on 4.19 there’s a huge performance hit. For the records, on Xbox One X the same chapter is running almost all the time at a native 4K (using dynamic res option of 4.19). On the original Xbox however, even at 720p with the same settings like those in 4.18, the game is running between 20-23FPS. After a few debug test it is more than clear that is GPU related problem (frametime is between 65-70ms).

My question is - are there any specific 4.19 changes that can impact our performance and also, does anyone know any specific optimized settings just using the variables in the BP_ocean class?

Thanks in advance.
