It's a bit of pain in the ass to setup. You need to hack resolution, WideScreen, and CPU-affinity (the game goes crazy if you let it run on more then one core). Controller support is pretty bad too, so you have to custom configure it. After all that I got it working in 1080P, mostly steady 30fps (R6670) - saw some lip-sync issues thoughLord Error said:SH2 has hard edge shadows on PC, that alone makes it look really bad in comparison.
Graphically the lack of soft-shadows hurts, but it's still a lot better then what I've seen of HD collection (especially the fog).
Ironically I don't think any of the SH2s were the "perfect" version - PS2 used vertex-flashlight which does occasionally look off. PC took a hit on shadows and fog but improved the flashlight.
Does anyone know if XBox version had soft-shadows? (I know fog and flashlight were like the PC version).
