Funcom plans to further expand PhysX integration into their games

without comments

Last year, Funcom has announced the integration of “server-side PhysX” in Dreamworld engine, a technology behind popular MMO titles, such as Age of Conan and recently released The Secret World.

Rui Casais, Chief Technology Officer at Funcom, has joined us today to shed some light on how the company plans to further utilize the PhysX engine in their current and future projects.

PhysXInfo.com: So what exactly is the server-side PhysX, integrated into Dreamworld engine?

Rui Casais: One of the most computational expensive operations we do in our servers is collision checking. Due to the nature of PC gaming, we can never trust the client and have to therefore validate all the player movement in the server.

We had a homebrew collision system that worked ok, but when it comes down to it nothing beats the performance of a physics library like PhysX for collision checks.

In addition to this the addition of PhysX makes it possible for us to do more interesting physics simulation in the future, collision is just the beginning.

PhysXInfo.com: Since PhysX SDK has replaced your own collision detection system, has it resulted in any performance improvements or ability to implement new physics features?

Rui Casais: Server performance doubled when using PhysX, and we plan to expand on the physics side of gameplay in the future, although that isn’t a simple problem to tackle. But we like challenges!
