Steam forums are such a dumping ground for questions that never get answered so I'll try here, as if it would yield better results.
Something that has had me pulling my hair out lately is the fact that it will not launch. I played it perfectly fine earlier this year (about a month ago), max graphics even. Although I uninstalled it after it "Got old" to make disk space for another game. When that one "got old" too, I came back to Black Mesa, only to find that it crashes my display driver the moment a map loads. I've had that issue before on Counter Strike Global Offensive, Left 4 Dead 2, and Portal 2. I was able to fix them though, I can't remember exaclty how, I think it was -autoconfig or something like -width -hight, not sure. I kick myself for never writing it down each time.
If its of any significance the times I launched it with -console mode, the console had 3 instances of "shaderapidx8::created3dtexture: invalid color format!"
Occilates between either launching and crashing immediately; Launching and then crashing the display driver (Intel graphics..... has stopped workign and recovered) forcing me to end the process manually in order to prevent a crash loop followed by a BSOD; launching and playable, but display is 100% nonfunctional...
I once even got a stable version that didn't crash, albeit the screen was blank. I loaded a map (blindly) via the console and everything seemed functional... except the display. I've tried the windowed mode, the dxlevel thing, the borderless thing, several resolutions, safemode, only one that provides interactive interface is launching it with -console in the paremeters which prevents the background.bsp from running on start.
I've swam through several forums both here and on the "official" site, have not yeilded any results. I've reinstalled 4 times now, verified the files 2 times each.
All other source engine games work flawlessly (except Garry'smod, though most of the problems there are caused by the horrible integration method of the steam workshop) Half Life 2 runs flawlessly. The Black mesa I'm talking about is the retail version.
And as a typical protocol for help threads of this nature, here's my DxDiag printout: Operating System: Windows 7 Home Premium 64-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_gdr.150427-0707) Language: English (Regional Setting: English) System Manufacturer: Dell Inc.

and with that, I return to sitting and twiddling my thumbs. You provide some optimistic insight on to my problem, and you'll become my favorite person on the planet or something. I'm at the point of begging.
