Text Mashing
textboxes in dialogue mode is significally faster when mashing with both ENTER on the keyboard and Left Mouse Button. Not really a glitch but in speedruns you want to go fast, and thus abuse as many mechanics as you can. It works like this because you're basically upping the input frequency, making boxes scroll by very fast.
coc Warp
When an object or actor falls out of bounds and into the void in the bethesda gamebryo engine it will respawn in a pre determined spot on the map called the "CoC" (Center on Cell). This isn't as much as a glitch as it is exploiting an engine failsafe mechanic. This can be useful in speedruns to speed up backtracking, or to go somewhere you want on a map faster.
Reload Dashing
Reload Dashing is a Fallout: New Vegas glitch that allows you to slingshot yourself in a direction very fast.
To perform the glitch, get a weapon with a one-by-one bullet reload animation (.357 Magnum Revolver, Cowboy Repeater, Hunting Shotgun etc) and two different ammo types that fit the weapon. Then simply bring up the gun, move in a direction, swap ammo and bring up the pipboy, unequip the gun and bring the pipboy down again (Whilst still holding the movement key).
If you did it right you will have ridiculous speed for a second, and by binding your gun to a hotkey you can bring it up again and repeat the process for fast chaining.
The fastest way of doing dashes is actually to double tap the swap ammo key (2), press pipboy (F2 or TAB), then fire (LMB usually), Up on keyboard to select the right gun (357 Revolver most likely) ENTER on keyboard then TAB to bring the pipboy down.

To save yourself from fall damage in case you get launched up into the sky simply press quicksave and quickload. Although the glitch works on consoles saving yourself from fall damage will be difficult and cumbersome due to no quicksaves.
Getting launched into the sky can also make you end up standing in mid air if you stop holding a direction when start going up. You will continue to stand in mid air until you either move or save/load. This is the only method of dashing in the air, since the glitch depends on the walking animation for it to work.
Dashing works because the one-by-one bullet animation weapons have a glitched animation, where it will force movement at the end of it. When you unequip your weapon during this glitched animation and hold W the game will add tons of extra speed for the duration of the glitchy forced movement.
Third Person Interaction
Third Person Interaction is an exploit or glitch in Fallout 3/New Vegas that allows your character to interact with objects through walls. Simply go into third person, rub your face in the wall and twist the camera a bit if needed. When you see the prompt at the bottom of the screen, just use it!
Time Stop
This glitch stops time around you and lets you walk around in 'pipboy mode'. By mashing the "Place Marker" button whilst bringing up the map screen you can freeze everything around you and still walk around. To undo the glitch simply press on yes or no.
Don't walk too far away though since the game still thinks you are in the pipboy, and will not load new chunks of the world until you deactivate the glitch (or crash if you walk far enough)
Item Duplication
You can duplicate an item spawned in a container (spawned dead bodies also work) by depositing a stack of 6 or more other items with weight, then withdrawing them by pressing LMB and A almost at the same time.
The reason the item needs to have weight is because of the confirmation screen you need when withdrawing. If the item has no weight (such as ammo or meds) you will not get a confirmation screen.
The reason you can't dupe items from your inventory is because those items have a Reference ID, whilst items spawned in containers does not. Read more about item ID's here: http://fallout.wikia.com/wiki/Form_ID
This glitch works exactly the same in Fallout 3 as it does in New Vegas, and should also work on consoles (Only tried it with a controller)
Speedcripple
Speedcripple is a Fallout 3/New Vegas glitch that will add speed on top of your normal movement speed by quickloading at a precise timing. It works because when you cripple your legs, the game lowers your movement speed, and when the legs get healed it adds the speed back. So by quickloading (and thus "repairing" our legs) at a precise time when our legs get broken we can make the game add speed to our character with 100% movement speed, resulting in you moving about 150% speed.
This glitch is pretty precise and has a different timing on different hardware (and is also not possible on consoles due to lack of quickload)
This glitch also has negative synergy with the Reload Dashing glitch, since it makes your character move with the "crippled legs" animation and Reload Dashing requires the regular walking animation.
Block Boosting
Not useful for any PC runs, but it's a neat technique that I want to show.
A trick that only works with the gamepad control scheme (so controller on pc/console only) By blocking and jumping in a specific rhythm you can gain almost double the jump velocity.
Dam Rock Jump
Brief tutorial on how to do the dam rock jump (for glitchless/consoles) on a controller. Same principles apply for a Keyboard+Mouse I guess.
Ammo Swapping
Ammo Swapping allows you to load the wrong kind of ammunition into weapons. This glitch only works in Fallout: New Vegas, both PC and Console. However you need a controller to actually perform the glitch on PC.
You require 2 guns and ammunition for one of them (preferably one with lots of cheap ammo)
Equip the weapon with ammo and hold the Hot Key button (RB on an xbox controller)
Whilst still holding the Hot Key button, tap left on the left stick to go over to the ammo screen then bind the selected ammo to your hotkey of choice.
Now equip the other weapon and press the ammo hotkey, and you should load the ammo from the first gun into the second but still keeping the properties of the second guns ammo.
Level Skipping
Level Skipping is a glitch that allows you to basically raise your level really high with minimal effort. Note that you don't actually get to allocate any extra skills from doing this glitch.
All you want to do is to have Auto Save on Travel enabled, and exit a door to another cell/the overworld at a specific timing.
The timing is roughly when the "LEVEL UP" text in the bottom right is done fading out.
When you're on the other side of the door, simply reload the autosave, do a 180 and repeat it until you're satisfied.
Stop Hopping
Alterntaive names: Bunny Hopping, Circle Jumping
The effect of this technique is identical to Block Boosting, except it's easier to perform.
Inputs are flick mouse, jump, hold forward, release forward when landing, jump again and hold forward.
It's an easy trick to learn, but requires some practice to be able to chain it reliably.
Infinite Dashing
Infinite Dashing uses the same glitched animation that Reload Dashing does, but in a different way. Infinite Dashing is as the name implies, infinite. As long as you keep holding forward with this glitched animation you will keep the speed.
What makes the glitch troublesome is that it drops if you change the animation. Changing the animation includes stopping movement, falling, swapping weapons and several other things.
You can however chain quicksaves and quickloads in order to keep the speed in the air, and thus fly across the wasteland.
You perform the glitch easiest by having Grenade Launcher and .357 Revolver bound, shooting the grenade straight up into the air, swap to the revolver and perform a reload cancel as fast as you can and then pull up the pipboy. Whilst swapping to the revolver you also want to start moving forward too. When putting down the pipboy (Don't click anything in here) you want to time a QSQL so that it happens when the grenade explodes.
(Shoot Nade, Swap to Revolver, 2 2 LMB F2 Hold W, TAB QSQ)
If you do it right, you will gain tremendous speed and probably crash the game due to going too fast.
The standard 5 Agility is barely enough time to do the reload animations in time before the grenade hits the ground, and the more Agility you have the bigger window you have to perform the inputs.
If you for some reason can't move or have glitchy movement, try jumping and tapping W for a bit. If it still doesn't come back then you have to redo the glitch.
As this glitch includes breaking legs and QSQLing, the infamous "breakable" version is back, but in a minor form. You want to have your legs actually crippled for a guaranteed "unbreakable" speed.
