Heavy GPU/CPU performance spikes

Title: Heavy GPU/CPU performance spikes
Reproduction Rate: 100%
Blocker? Kinda yes.
Details: So it seems that water rendering is really heavy on the rendering system, my guess that the water rendering is not optimized. Or we need other water objects for Unity. Maybe so lighter objects.

Steps to Reproduce: In a scene walk near the big sea/lake and have the camera straight over the sea. You will notice huge performance hits. When turning away from the water it drops instantly.
Check screenshots.

I checked another scene where there is much water and I get the same performance hit. Ghost/Lag walking and graphs sky high. For some reason the FPS is really good, but game experience is the opposite.

 

Here's a little info from being logged in today. I didn't really play much though, travelled around, visted various scenes, did The Rise for a few mins,etc. I'm getting really high CPU usage at times, and memory usage is still building up throughout the day. I'm still in game as of 5pm EST and am now down to 3.8gigs of 16. By the way, @Feeyo , what is that overlay you are using and where can I get it?

 

Hey @Sorthious , I am using (Gallium3D Heads-Up Display) overlay for the graphs. This can only be used when using the open source drivers that make use of mesa.
I see you also use the amdgpu open drivers from amd, so you can also use it. You can use it for any game, just change the executable at the end.
