- Downscaled lightmap, since blurring will make this unnoticeable anyway (TODO: make this optional) - Render LOS in fewer passes by using a shader - Use light volume to calculate LOS - This also means we can use the override texture to render the diving suit obstruct effect - Don't render bunks and labels onto LOS background (TODO: add the option to render back into the LOS background, i.e. just use multiplicative blending as if it was the lightmap) - Prefer SpriteSortMode.Deferred over all others, prefer SamplerState.LinearClamp/PointClamp over all others - Remove shader blur in favor of geometry blur (TODO: improve on this further, right now it has a few artifacts) - Trim light volumes - Do some weird shit with the background particles (use DrawTiled instead of relying on SamplerState.LinearWrap, because that's faster somehow :/ ) - Pressing up/down in the console only returns a typed command now
