here's my wkSnow config:[Snow]
Enabled=1
Size=Normal
Particles=0
ForceNoSnow=0
Particles=0 is an invalid value for the game. That means "use the default" and forces the regular amount of snow. Game crashes with 0 actual particles. You can set Particles=1 but at least 1 snowflake will still fly.
You can also enable "God Mode" (Ctrl+Alt+Clear) and press Ctrl+Shift+Num- two times to make the snowflake freeze in place. Lastly, you can use Size=Small and the snowflake will just be 1 pixel (multiplied by your current gfx scale) in size.
As ridiculous as it may sound, this is the solution for now. However I will probably add an option to disable debris directly in SuperFrontend (this should be an easy flip). It will not even perform simulation, so you should see the difference in performance.
