I'm afraid not at present - these presets were created before Arnold GPU was released and it's is a lot less forgiving about native Max maps, including but not limited to Forest Colour, which will impact probably most of our presets. In the event that the map is unsupported, it appears to use the diffuse colour instead which may be why some presets like grass looks OK from a distance. We will look into how we can support GPU mode in the future, but in the short term, it's probably going to involve having to modify the materials a bit.
