I just started playing L4D2 to see if it worked. It turns out that it does except this pesky lighting bug. This happens sometimes, and other times it doesn’t. Any help would be great.
have you tried uninstalling/reinstalling? assuming you own a legit version?
I haven’t tried that yet. This ‘effect’ takes place less often when i verified and defragmented the files.
What GPU are you using?
Try different graphics settings… textures and stuff.
And upgrade your drivers.
