For those wondering why Rage for the PC performs so badly with Nvidia cards, and is unplayable with most ATI cards...
The problem is Rage's new engine uses openGL. It seems like after all these years, id software still makes games that perform best using openGl.
The problem is, most graphic development over the last decade has mostly been for DirectX, not openGL.
id software put out a product, without first testing it and optimizing it for current video cards.
This is why they're blaming the driver developers, instead of taking responsibility for f&^king up.
Shame on John Carmack and shame on id software.
