As i didn't see mentioning it anywhere:

The effect of the mysterious Radeon bug has been greatly reduced.

I finally can play again with activated particle effects. There are still some issues left - getting blinded (screen turns completly white) based on position in some gals, some Termite Mounds blinding, big colored bars in some gals hiding you and your enemies from view but overall I can really play and fight with activated particle effects - big thx to the dev team.

This is definitly a good 'nerf'
