port/linux/game/vr_graphics.c (after HaloCE-Quest-VR's, CC0) sets the
game's own effect switches each frame before drawing: "high" (the
default) draws everything as before; "medium" no object shadows,
environment reflections or lens flares; "low" nor specular light, bump
maps, detail objects (grass), the screen's fog layer, contrails, weather
or camouflage's second pass; "max" is "high" with per-pixel model
lighting and 512x512 shadow maps (d3d8_gl.c asks halo_vr_graphics). A
switch the game changes (scripts, console) is taken as its wish and
combined with the preset's. A client in another's game keeps grass, lens
flares and the fog layer as the host's rules have them; cheats.c leaves
the environment parts the preset may keep off there (shadows, specular,
reflections).
