Most of the shader enhancements are the same, in fact you can import your pro presets over to 2, there are some additional tweaks and reworkings but I suppose a lot depends on your setting up of those tweakable values, one persons RWE2 enhancement can potentially look completely different to another persons. The main thing with RWE2 over 1 or Pro is the additional overlay (sound and HUD) and the other features outside of the game itself, namely the content explorer, QD enhanced stops (within the RWE2 HUD environment) and also the consist creator, all I'm trying to say is RWE2 is a bit more than just an "improved" shader injector
I see... so really it's more of an update to give file and GUI features, but the underlying shaders are the same. Got it.
