In Hexen: Death Kings of the Dark Citadel in the very beginning of the 3rd episode if you turn to your right you will see a large pillar and it will have exploding “puffs” of fog around and behind it. However, this only seems to happen if I am using jXCCP_123.pk3. If I use jXCCP.pk3, I see only darker clouds floating in the fog (similar to the sky). This is with an Intel CPU, Nvidia GPU and with build 926.
Each gives a different feel to the environment.
Are people with AMD equipment also getting this effect?
