Is there a more recent game that has taken over that position, or is Crysis still the benchmark? It's super old now! (not really into games anymore so no idea myself)
Crysis was hard on systems partly because the graphics were good and partly because it was not well-optimized. Game graphics have improved since then but they don't tend to take your system down as hard because they are better written. That's why Crysis is still a joke.
