I’ll get this bit of reassurance out of the way: Infinite runs perfectly. Our demo PCs were admittedly above average: an AMD FX-8120 (an octo-core CPU) and a single card in the AMD Radeon 7900 series (I didn’t have time to verify which one), alongside 16GB RAM on Windows 7. With that considered, I didn’t experience any hiccups, frame rate dips, no texture pop-in, or crashes.
Digging into the settings menu, here’s what was adjustable…
[*]Anti-aliasing
[*]Texture detail
[*]Dynamic shadows
[*]Post-processing quality
[*]Light shafts
[*]Ambient occlusion
[*]Object detail
[*]V-sync
[*]FOV (a slider, with no listed value)
[*]UI margins
[*]Toggleable highlighting of “searchable” or “important” objects
An Irrational developer told me that Infinite is running on DirectX 10, but that it does take advantage of some DX11 features.
