Last week I put the free-to-play mech game Hawken through its paces with some in-depth performance testing, but elected to turn the NVIDIA driven PhysX option off. If you're curious as to how PhysX alters the look of the game and its performance, read on for a second in-depth performance test. And if an arcade-inspired mech game sounds like your thing, you can download Hawken now on the official website.
Note while AMD users can technically take advantage of PhysX, the work is given to the CPU, which typically results in very poor performance, and as such, is not recommended.
Note testing was done on maximum settings with VSync off during the first portion of the training mission, before it fades to black -- this is all for consistency's sake. The mission is a little over two minutes long and features an industrial area in broad daylight.
