RE: Issues

There was a huge bug in HL2 after the "HDR" update Valve had released in the middle of this year: when playing in non-HDR modes you would result in some levels appear overbright as the update lacks compiled lightmaps for some levels. This bug was reported on the steam forums ages ago but I don't know if there was an official reaction on this.
So to answer your question about weird effects we should first determine if this is a known bug in HL2 itself or a configuration/hardware-specific problem you had run into.
