According to a Valve Engineer, the Steam Machine specs outclass the most common PC configurations. The company relied on its own hardware surveys to choose the system’s components. Even as an entry-level option, Valve claims that 4K/60 fps performance is realistic, despite a memory-limited GPU.
But can it play Crisis on ultra?
Possibly not, crysis is single thread bound due to it being a 32 bit application. You can technically run it as x64 but that’s cheating.
What? 32bit has nothing to do with how many threads it can use. Just how much memory it can address.
