Intel provides game developers with tools and resources to help them maximize the potential of their games. I would strongly encourage you to take advantage of these tools when creating your game demos. In particular there are 3 products that deserve specific attention:
Intel Visual Computing Source: This is your source for all things visual computing at Intel. It's currently in Beta and is the way in which you can make sure you have access to all the latest tools and content.
Intel GPA: This the graphics performance analyzer that our application engineers and partner software vendors use to ensure that their rendering pipeline is running as efficently as possible.
We hope that you take advantage of these resources. If you have questions about them, don't hesitate to ask!
