[15.32] Uranium Ore causes bad Framerate

[Algo-ryth-mix]

Whenever my Player gets near to a Patch of Uranium Ore the Framerate drops severely (noticeably under 60, between 20 and 15). I only experience this with Uranium Ore. My Pc should be able to handle such a load pretty easily. (Ryzen7 1800x@3.85GHz 16Gb Ram & Gtx1070HOF 8Gb VDDR5). I noticed that some people have reported bad frame rate in 0.15 but I didn't find one that was so specific.
Attached are some images with screenshots &the log & the save:

Can you try if changing "Lights render resoltion" to minimum (0.25 I think) improves the FPS?

[Algo-ryth-mix]

changing this to 0.25 does nothing

Note that this also happens when using the Map + Radar View

Thanks for the screenshots with debug info. I think I fixed it for 0.15.33.

Out of curiosity - what was the culprit here?

On the screenshots I noticed big increase in draw calls (from 239 without uranium ore, to 2067 with uranium). We render draw glow layer over the ore. I move rendering of the glow to higher layer, so it doesn't break batching if uranium ore sprite and the glow sprite don't fall into the same sprite atlas.
Note: I saw the increase in draw call count on my computer too, but didn't experience any FPS drops. I have GTX 750Ti.

I can confirm that Version 0.15.33 fixes this issue, gliding over uranium ore is now buttery smooth
