   Where can I find techniques slideshows?
  I like to read whitepapers and slideshows from nVidia and other companies, but most of them I find in other people posts, so I would like to know where can I find more slideshows from game developers, etc about techniques they used in modern games...   
  The ShaderX books are good, other than that NVidia have a whole section white papers on their site. You could download and install RenderMonkey and FXComposer too, they come with examples.   ;  I dont know about slide shows but citeseer is THE place to find whitepapers...google it and be amazed.
