Seems to be quite demanding on hardware, as it goes to 1 FPS on my laptop with all effects disabled. I can run Leadwerks demos even with postshaders and water at 30 FPS on the same machine.
You want to get that machine checked out. I'm getting framerates of about 10 times faster than the Leadwerks demo, with everything max'ed.
I ran dxdiag and dx7,8, and 9 are all working fine.....
Nevertheless, your DirectX is not up to date. That's definitely a DX9 file you're missing.
Very nice stuff. I get frame rates of around 350 on a Geforce 8600GTS, which is pretty comparable to the sort of speeds I get with my own TV3D-based engine. Nice to see the grass being affected by point lights too, that's something you don't always get. Good stuff.
