--- Comment #35 from Jeff MacLoue  ---
Verified The Witcher 2 EE (latest GOG version) - the rendering issues are gone
with multiply_special = 1, no perceptible drop in performance. multiply_special
= 2 also works fine. multiply_special = 0 gets the black spots back - no
surprise here.

PS Unfortunately couldn't verify the performance - the game lacks FPS display,
and GLXOSD didn't work right away. Specs: Intel Core i5-8600K, 64 Gb RAM,
GeForce 1050 Ti/4Gb VRAM
