Recently, I purchased an old IBM laptop for basic stuff (internet, email, blah blah blah), and of course, HL mapping. This isn't actually a mapping related issue, but I figured someone else might have had the same problem at some point.
You see, this laptop has a really old 16 MB video card, and there are several problems with it, but most annoyingly, skyboxes render really strangely. Check it out:
The video card has the newest drivers installed, and Half-Life has the most recent updates. Anyone know what's going on?
