ok, pretty cool.
today I tried to load half-life and I get this little message: I tried updating my gfx drivers, but no change. I haven't changed any video options and I've never had this problem. the only thing I did steam related close to the time when it happened was I tried to download the SDK without having HL2 installed (i didn't know it wouldn't work without it, but it makes sense).
Was there a steam update recently? If I can't get it to work Direct3D works, but the general consensus is that OpenGL is better for HL so I'd like to get it working again.
Thanks for reading! = )
