In my opinion the engine must suck if it looks like this and requires such high system specs.I think they took on too much at once.
Those glass windows aren't needed.
And real-time lighting looks cool, but not when it's making even top-end systems chunk a bit.
I really wish developers would stop trying to do real-time lighting for now. Start making your games with FSAA in mind for all systems, rather than real-time lighting. Swinging lights don't look nearly as nice when they create tons of jaggies.
