All those are relatively new video cards aren’t they? I dunno maybe older video cards and slight changes to the config file will cause the flashbangs not to work, I dunno what to tell you man.
The x600 is 3 years old. The 8800s are about 16-18 months.
See if it still does that, it seems stupid for Steam to give those running DX7 an advantage. I bet they fixed it.
Also, I hate to keep bashing on CAL, but they aren’t exactly the most accurate source of information. If you go back a few years you’ll find some good lols on their forums.
