After careful consideration I have decided to transfer all hardware review activities to a new domain. I purchased Hardwareasylum.com in 2012 and have been working hard to build a new and improved Ninjalane on that domain. If you are reading this you have reached one of the archived articles, news, projects and/or reviews that were left behind during the site migration.

So why is that?? The quick answer is hardware and programming limitations. Breaking something into smaller pieces is a complex problem for game designers as they have to account for everything, assign rules to falling debris, and determine how you can interact with different materials. This process is very costly in terms of CPU calculations so game designers purposefully limit the environments to ensure a smooth gaming experience.
PhysX is the answer to this fundamental problem and finally gives game designers the ability to add realism to their games. No longer does a NPC simply fall out of a window, now that character can rip curtains off the wall while shattering a pane of glass before falling to their death. All of this with perfect physical properties and absolutely no additional load on the CPU.
In this article we are going to explore what PhysX really is and how it applies to different games and more importantly how this technology affects performance in those games.
