TF2 Tweaking Guide

Just thought I'd post this here in case there was someone that didn't know of these commands. Basically this is for if you have a computer that can run default TF2 on the maximum settings ingame, and want to pump it up even more to make it look even better.

There's some pictures I'll add for comparative reason that'll show how different some stuff looks, that might or might not be shamelessly stolen from other sites that have a guide like this >_>

Anyways.
Basically the best option to keep all of the commands on is to stick it into an autoexec.cfg file (edited as a text file in wordpad/notepad) in your \team fortress 2\tf\cfg\ folder.

COMMANDS

mat_picmip -10 The default usually is stuck on -1, but sticking it to -10 will put up most of the textures to maximum quality. You'll basically be able to read most of the text on small posters and the engies blueprint. You'll notice the difference best on props, water, and various hand models for the different classes.
Comparative examples:

r_lod 1 will remove "pop-in", that is, the further away the model is the less graphical detail there will be on it. You can switch it between anything from -8 to 8 but anything else then 0,1 or 2 is marked as cheats. 0 is buggy so it's recommended to stick with 1.

mp_usehwmmodels 1
mp_usehwmvcds 1
These two generally should go together, as they replace the game models for the ones used in the "Meet the..." videos. They'll basically have more expression and detail, especially in the face. The first command switches out the models while the second should add the animations for them. Default on both is otherwise 0
Example:

cl_new_impact_effects 1 Uses the source engine to render impact effects. Basically dust, sparks, etc for when your bullets or weapons hit somewhere. Default is 0

cl_burninggibs 1 Speaks for itself. If you get gibbed while on fire, your bits and pieces will be burning as well. Default on 0

mat_specular 1 Puts on specular highlights of models. Better reflection, I guess? Default 0

mat_parallaxmap 1
mat_aaquality 8
r_threaded_particles 1
r_threaded_client_shadow_manager 1
cl_threaded_bone_setup 1
cl_threaded_client_leaf_system 1
mat_antialias 16

The rest basically just put the antialiasing as well as, well, what they sound like. Not exactly sure how much they change but it still makes it even prettier.

mat_motion_blur_forward_enabled 1 Will add motion blur for when moving forward. For the other directions, just delete the "forward" bit.
Although this won't be very visible unless you crank up mat_motion_blur_strength 2. You can crank it up to at least 10 if you want, but it'll be a bit much. Test around with it as you please.

For bulletholes etc to last longer:
Go to Options -> Multiplayer and click on the Advanced tab.
Set Multiplayer Decal Limit to 4096.

I might have missed some commands. Hell, you might know about these already, but it's still a nice guide to have if you feel the need and effort to make your TF2 even shinier. I have most of these on and it's not a major FPS difference.

Let me know if there's something else that needs to be added.
Oh, and use at your own risk.
