"You have a choice between the natural stability of gold and the honesty and intelligence of the members of government. And with all due respect for those gentlemen, I advise you, as long as the capitalist system lasts, vote for gold."
- George Bernard Shaw
There's a new demo available that demonstrates texture compression done entirely on the GPU. You'll need a DX10.1 card (Radeon HD 3000 series only right now) and you need to have Windows Vista SP1 installed.
You can toggle between the compressed and uncompressed texture with F5.
