Fallout 4: New Vegas is an ambitious project to say the very least and it has been getting a lot of attention from the fans are plenty of people are concerned about the lighting and different presets that could potentially be used in order to bring the game to life. The developer talked about reshade and END presets and the following is what they had to say in this regard:
ENB and Reshade are fantastic tools that allow users to customize the look of their game, and can fundamentally change the overall tone of a game with the tweaks they allow. For some older games, they can even enable the use of post processing effects that these games would otherwise never have.
Reshade and END presets are great but they do impact performance and the devs of Fallout 4: New Vegas explained that they will not be using these presets for the game. While some systems will be able to handle these just fine, they do hit performance pretty harshly. The following is what the devs had to say in this regard:
Depending on the hardware of the user, they can have a serious impact upon performance. As well, much of what these tools enable can be done natively within the Creation Engine by utilizing the various imagespace and weather modifiers available to our effects and level design teams, so such a potential performance hit is unneeded. To that end, F4NV will not have any official Reshade or ENB presets included, and none of the images we have showcased have these effects applied. Indeed, none of our shots have been edited, instead being taken straight from in-engine.
Whether or not you agree with the direction that Fallout 4: New Vegas are taking is up to you but this does make sense to a certain degree. This way, more people will be able to enjoy Fallout 4: New Vegas in the form that the devs want players to experience the game. Otherwise, it would be a limited experience for people that do not have powerful enough systems.
The devs are hard at work and we can all appreciate all the work that they have put into making Fallout 4: New Vegas.
