Only the latest doom uses a texture streaming system. The other dooms are also on older iteration of this engine and each iteration uses largly different cvars. When looking to maximize texture quality on doom 3 i advice you to look up specific guides for it. However ill be handy and give you one here.

Change your seta com_machineSpec in your config.cfg to seta com_machineSpec "-1"

then put these at the bottom of your config.cfg Change the lines to these values if they already exist.

seta image_downSizeLimit "0"
seta image_ignoreHighQuality "0"
seta image_downSizeBumpLimit "0"
seta image_downSizeSpecularLimit "0"
seta image_downSizeBump "0"
seta image_downSizeSpecular "0"

Does this work on older dooms? :P

Damn! Great guide! I'll be sure to try this next time I'm playing on a computer at NASA!

And also at 32k i think the weapons stop having pop in textures.

it's just the novelty of being able to run 32k textures that makes you feel cool.

Why would they? Unless we come up with a way to augment our eyes, we wouldn't be able to see it anyway...

@demontrace in about 6 years people will love that I found out that 32k textures are possable.

So what's the point of this guide? To get you to crash your PC? Brilliant.
