Basic guide on Versions and Patches for PC

This game was originally released as Divinity 2 Ego Draconis. This version ends after defeating Zandalor and the Divine. After this an add-on/DLC was released called Flames of Vengeance. This added the entire Aleroth section and ends with defeating Behrlihn and Ygerna. 
After these two releases Larian released Divinity 2 DKS (Dragon Knight Saga) containing both games. 
There exist multiple patches for the Ego Draconis and DKS version many of which do not contain patch notes and are not easily findable today. These patches influence the balancing of the game heavily. All of these versions were available to buy on disc. Eventually it was decided to release the game on steam. For this they chose the DKS version of the game with all balance patches already applied. This version is called Divinity 2 Developers Cut. 
To speedrun the game I used an unpatched version of the DKS game that I installed from disc. Discs of this game can be difficult to find today but so far I have not found a better option than getting a disc or finding and old iso and patching it using the DRM free patch found in the Larian forums (listed under resources).
The game can still be run using the Developers Cut version but this requires some different strategies and is about 5-10 minutes slower depending on RNG and execution. If you want to start running this game try the Dev Cut version first.
Happy speedrunning,

Fix game crashes

This game is a buggy mess and crashes all the time. The most common crash is the infinite loading screen which can occur at any loading screen and is really frustrating. To fix this first try turning of Lockstep mode in the graphics options and apply the 4GB patch (linked in resources). If this does not fix the issue also try to run the game in windowed mode by changing the launch options of the .exe file. The steam discussions also contain some useful threads. 
If you run this game and use OBS to record you have to use Screen recording and not Window or Game recording otherwise the game will crash during the transition from the Ego Draconis part to the Flames of Vengeance part. This is likely due to the Ego Draconis part getting closed and the FoV part being opened as a new game.
