This thread is for information for anyone who wishes to undertake a Witcher 2 speed run.
Build
The best build for speed running in Witcher 2 is one that uses bombs and the igni (fire) sign as it is effective against groups, and does not require high level swords or armour. The best bomb is Grapeshot (Beehive) which does 30-40 base damage (60-80 with both Alchemist skills) and its diagram can be purchased from Cedric in act 1.
You require the following skills:
Training: 2 levels of Vigor Regeneration, Fortitude
Training: 1 level of Parrying (prerequisite), Dagger Throwing (useful)
Alchemy: 2 levels of Alchemist (100% bomb damage)
Magic: 2 levels of Destructive Magic, Magic intensification, Enhanced Igni Sign,
Magic: 1 level of Enhanced Quen Sign (prerequisite)
This will give you 6 vigor, a powerful igni blast, and bombs that do double damage at level 15.
On the higher difficulties I'd recommend getting 1 level of 'Feet work' from the Swordsmanship tree to make it easier to dodge enemy attacks.
Walkthrough
I'm just going to briefly give advice regarding which choices are the quickest and which optional quests are worth doing. The exact route is up to the runner.
Prologue
Using Aard to knock soldiers off the walls is quicker than killing them with your sword.
Convincing Aryan to surrender is quicker than fighting him.
The fastest way to escape the dungeon is to go down to the lower level and save Aryan. This skips most of the stealth section as Aryan shows you a secret escape tunnel.
Act 1 Flotsam
Buy a Robust Witcher Sword from the Mysterious Merchant. The only better Silver Sword in this act requires you to complete the Nekker + Endrega quests.
The Kayran trap is quicker than hacking off a tentacle because it doesn't have the cutting cut scene.
Helping Roche at the Elven ruins and siding with him is quicker than helping Iorveth at the ruins (violent Flotsom has repeated cut scenes of non-humans being attacked) and siding with Iorveth (involves either slowly walking through Flotsom with Iorveth or fighting a lot of soldiers). However siding with Roche means you have to do Roche's Act 2 and 3.
The only optional question worth completing are Troll Trouble and Mystic River. In Troll Trouble you can get the Hunter's armour diagram by helping the troll and by killing Dmitri you can get a Robust Cutlass. If you complete Mystic River in acts 1-3 you'll get some good armour that improves your signs.
Act 2 Roche
Buy a Robust meteorite sword and Poisoned Zerrikanian saberra from the Mysterious Merchant. These are the best swords you'll get in Act 2.
You'll be given Zireael's armor by Dethmold during The Blood Curse quest, which is the best non-craftable armour you can get in this chapter.
UPDATE: in the enhanced edition you can win the Princess Xenthia sword (steel) from Skalen Burdon by beating him at dice poker. The Blood sword (silver) can also be found in the tunnels under Vergen. Both are very powerful and free.
Complete the side quest Mystic River for the Act 3 armour.
Unsure whether killing or not killing Henselt is quicker. Both result in cut scenes that can be skipped.
Act 3 Roche
Get the Deithwen (silver sword) from the caves east of Loc Muinne.
Complete the side quest Mystic River for the Armor of Ysgith or Vran armor.
Unsure if rescuing Anais is quicker than saving Triss. Both involve fighting a lot of soldiers, though Dethmold has good armour and a great steel sword (Forgotten vran sword).
Saving Sila is quicker that waiting for her to die.
Don't fight Letho.
Act 2 Iorveth
Buy a Robust meteorite sword and Poisoned Zerrikanian saberra from the Mysterious Merchant. These are the best you'll get in Act 2.
Buy 'Dragon scale armor' from Mael. This is the best armour available in Act 2.
Let the mob kill Stennis as it's quicker than going to Henselt to get his blood.
Complete the side quest Mystic River for the Act 3 armour.
Act 3 Iorveth
Get the Deithwen (silver sword) from the caves Iorveth goes into at the start of Act 3.
Complete the side quest Mystic River for the Armor of Ysgith or Vran armor.
Save Saskia rather than rescue Triss. It's much quicker as you only have to fight one golem, rather than dozens of soldiers. You'll also only need a good silver sword for his act because you won't be fighting humans.
UPDATE: in the enhanced edition you can get the Forgotten vran sword (steel) by completing the 'The Secrets of Loc Muinne' quest.
Saving Sila is quicker that waiting for her to die.
Don't fight Letho.
