The files in this post are named for umod 1.0 so unless you take the time to rename them according to how 2.0 dumps them they will never get applied on 2.0. There's more options in 2.0 for supported formats, but I doubt there's any change in quality.
however it is easier to find the repeated textures at different resolutions that the game uses as it changes scenes since it puts it does 512x512 and 1024x1024 in the file names, when you watch the transformations you can see the changes in details on the models as it changes views. almost seems like mipmaps are having some affect on the details and the final close shot looks a good bit better (but I could be just imagining that), I think the photoshop dds plugin had some options on that end
just make sure you enable global hook, and also you have the option of copying the d3d9.dll from the umod folder into the same folder as the game's exe file, you can add the exe in umod, but don't try to start the game from umod, start it like normal with umod already running.
then make sure you add the zip file on umod and it should start replacing textures, but unless you see a tab show up for "application" and add the files under there, it's not going to work, also you need to do this before the game gets past the opening fmvs, after that it loads up a lot of the game textures and you wont have any effect since they'll already be in memory
