Scatterer Effect on Mac Performance?

[Zosma Procyon]

Does the Scatterer addon have an adverse effect on the performance of KSP when it is running on a Mac? Does it slow the game down?

I've been narrowing my performance issues down to scatterer only. All other mods (Spectra w/out scatterer, planet shine, EVE) are working fine. I see 90+ fps on my M3 Max Pro at 4K resolutions (but I choose to play at 2K for obvious eye strain on the UI).

I go from 120-90 fps to 30-25 fps when I bring in scatterer. I love Spectra/Scatter on my Windows rig with a RTX40xx... but yeah... Whatever post process technique scatterer is using, doesn't play nice with Mac OpenGL/METAL, etc.

I know this is an old thread... apologies!

I think I have further narrowed my performance woes down to Clouds and Scatterer. Scatterer by it self runs decently well. Basically, my mod list in short:

  √  Spectra                                       v1.6.5      1.12.5                                                                       
  √  Spectra EVE Minmus geysers                    1.6.5       1.12.5                                                                       
  √  Spectra Scatterer                             v1.6.5      1.12.5                                                                       
  √  Spectra Scatterer for Minmus                  1.6.5       1.12.5                                                                       
  √  Spectra Scatterer Jool shine on Laythe        1.6.5       1.12.5                                                                       
  √  Spectra Scatterer vibrant sunsets             1.6.5       1.12.5                                                                       
     Spectra EVE 64k Kerbin clouds                 2.0         1.12.3  <-- nope                                                                     
     Spectra EVE Kerbin and Laythe snow            1.6.5       1.12.5  <-- have not tried, but says its laggy

I can mix and match a manual install of Scatterer and other Environment enhancement mods. But no matter what, when I introduce a mod that brings in clouds, I get drastic FPS hits. In closing, the above looks and performs well on an Apple GPU.

 

A little off topic, but once in high orbit, I found other performance hits related to how many Kerbals were being displayed in the bottom right of the screen. Limiting that, or out-right turning it off increased my FPS. Neat find.
