Post Metro Last Light: developer talks about CPU and GPU PhysX support

Metro: Last Light, sequel to Metro 2033 title, is aiming technology throne with DX 11, tesselation and support for GPU accelerated PhysX effects. PCGamesHardware.com had the chance to talk with Oles Shishkovtsov, Chief Technology Officer at 4A Games, about improvements that are planned for PC version of the game.


PC Games Hardware: You keep the support for GPU PhysX in Metro Last Light. If so can we expect some improvements or enhancements compared to Metro 2033 (e.g. soft bodies, debris, and destructible environments)? What graphics card do you recommend for maxed details in Full HD with Antialiasing? An upcoming Nvidia Kepler-based Geforce for example?

Oles Shishkovtsov: Yes, you can expect a lot of improvements, especially in destruction and debris. The upcoming Geforce cards will be fully supported.

PC Games Hardware: When benchmarking Metro 2033 we found out that the engine utilized more than four cores of multicore CPUs if we were using the advanced PhysX effects on CPU, so you are utilizing Nvidias PhysX SDK 3.x? Will all the advanced PhysX effects only be available in PC version?

Oles Shishkovtsov: That's the common misconception that PhysX 2.X cannot be multithreaded. Actually it is internally designed to be multithreaded! The only thing ' it takes some programmer time to enable that multi-threading (actually task generation), mostly to integrate with engine task-model and ensure proper load-balancing. So, 2033 used PhysX 2.8.3, and Last Light uses similar, a slightly modified version at the time of writing. And yes, advanced PhysX effects will be available only on PC.

Sounds good.

However, we are hoping that this time Metro will be able to surprise us with more than two minor particle effects (as in Metro 2033 ' while 'debris, smoke and dust' were promised) and it won't require 'upcoming GeForce card' to run those GPU PhysX effects with playble framerate.
