The elite texture pack was only delivered with the Collector Edition of Fallen Angel. I'm not sure if it works with Gold Edition since Ice & Blood expansion pack is integrated into the installation.
I have S2: FA - CE (from Retail) + S2: Gold from Gamersgate.
I do have the Sacred 2 high-res pack - and yes, it's installed.
But, seriously - I do not think it's worth running them w/ S2: Gold.
Elite Texture Pack was built for S2: FA (without Ice + Blood installed).
They didn't do Elite Textures for Ice + Blood expansion content.
I have all kinds of performance issues - stutters, game-freezes, CTD's, and other things when running this with S2: Gold.
Ain't worth running w/ S2: Gold, IMHO.
But if you can get it running better than me - please, share your tricks. :D
