  • Except for making your map simpler, there is no way to make VBSP faster (but VBSP is pretty fast anyway)
  • VVIS can be significantly sped up by applying certain visibility optimization techniques
    • Note: Sacrificing in-game performance to speed up the VVIS compile process is usually a bad trade-off; If you have to choose between suboptimal in-game performance or long compile times, the long compile times are worth it
  • VRAD can be sped up by applying lightmap optimization; that is, increasing the lightmap scale to decrease the number of lighting sample points
    • Note that high lightmap scales can look weird, and should generally only be used on faces where lighting is largely uniform, such as roofs facing the sky
