I understand that there have been a few similarly named threads as of late, however I believe that the source of my problems might be unlike the others.
Previously in G-Mod 12, I had been able to project dynamic shadows through the use of flashlight console commands, and in the G-Mod 13 Beta I had been able to cast dynamic shadows with lamps. When G-Mod 12 had updated to version 13, I was completely unable to cast dynamic shadows, though normal shadows were still present. I do not seem to have this problem in other Source games. I have repeatedly validated my game cache, reinstalled the entire game multiple times, and even tinkered around with some of the console commands, though still to no avail.
My video card is a GTX 660, so I don’t think any of my problems are due to hardware obsolescence. All my graphics settings are at maximum and I have frequently checked for updates for my video card.
I’ve been having this problem for a long time now and I’d like to know if there’s a way to fix it.
