Nope! In fact I've found that with reskins it's possible to actually bump down the graphics quality a bit since the reskins are generally higher-res than their equivalent vanilla textures, which helps smooth things out.

Well, in theory, using many custom retextures can have some impact on FPS.

The more detailed explanation, is that, usually user made textures, unlike the vanilla ones, don't include MipMaps, and due this, the game engine cannot use some intermediate texture resolutions, at different levels of zoom. On the one hand this fact might be considered as a downside of the custom textures, but on the other, this has significant impact on the quality of displayed textures. That's because the game engine for the most of time displays lower resolution textures, while displaying the highest resolution ones only at the closest level of zoom. This doesn't happen when using custom textures unless they are equipped with the MipMaps. Of course, it is not that in case of user made reskins the highest resolution texture is displayed all the time, as each unit uses 3 textures with different resolutions, and the engine anyway switches between those 3 levels of details, though it happens less frequently, as it doesn't have access to the intermediate resolutions provided by the MipMaps.

However in practice, I have not noticed, any significant impact of custom reskisn on FPS. So if you are running the game normally at Very High or Insane graphic settings, you really shouldn’t be bothering with them.

Oh, so that's what MipMaps are... Great explanation!
