id Software's programmer Robert Duffy updated his .plan file and among other things, he explains the graphics requirements for the upcoming game Doom III.
In short, here's which requirements are needed for the different quality setups of the game:
Ultra Quality (max. quality): for 512MB video cards. Each texture; diffuse, specular, normal map at full resolution with no compression.
High Quality: for 256MB video cards. Uses compression ( DXT1,3,5 ) for specular and diffuse and no compression for normal maps. This looks very very close to Ultra quality but the compression does cause some loss.
Medium Quality: for 128MB video cards. Uses compression for specular, diffuse, and normal maps. This still looks really really good but compressing the normal maps can produce a few artifacts especially on hard angled or round edges.
Low Quality: for 64MB video cards. It does everything medium quality does but it also downsizes textures over 512x512 and we downsize specular maps to 64x64 in this mode as well. |
