Dynamic Shadows Fix Okay firstly. I play Horror Maps. A LOT OF THEM! And thou, having Source 2007 games not letting me use "High" as an option for Shadow Detail, I went searching on the internet back and forth for a fix. (Lets face it. Dynamic Shadows look nice) I have found a workaround that has worked for me and will work for you.
- Go to the "Library" menu in Steam.
- Go to any Source game's Launch Options. (For me, Black Mesa and Garry's Mod) (Right Click > Properties > Set Launch Options)
- Copy and paste this in the Command Line: -force_vendor_id 0x10DE -force_device_id 0x1180
Go into the video settings for a BIG Surprise.
It may look grainy afterwards but check this link for Projected Texture tweaking.

FINALLY having a legitimate work around. Please spread this to Steam Forums, Facepunch etc.
From what I can brown townyze from this workaround, it makes Source think that you are using a powerful GPU where it can unblock Medium. When in reality your only using an Intel card. (However, this does not mean you are using that particular card.) And once again, please spread this to other Forums. Thank You and now... I gotta get back to finishing Hell's Prison.
IN DYNAMIC SHADOWS!!! Hope this helps! :D
