If Crysis 1 worked on your PC, then Crysis 2 should run without problems. Crysis 2 will require less while providing more.Does Crysis 2 require more from my pc than Crysis 1?
1. CryENGINE 3 is optimized for a balance of beautiful graphics and optimum quality

2. Right now Crysis 2 only supports DirectX9, so if you can play Crysis at DX9 and DX10 then Crysis 2

is not a problem

3. Current generation hardware can pretty much run Crysis, so since Crysis is less optimized, Crysis 2

is a piece of cake

4. CryENGINE 3 has less shaders and more motion blur to mask the edges

5. Buy the game. You won't regret it.Does Crysis 2 require more from my pc than Crysis 1?
They downgraded the engines it would run on consoles. It has lower requirements.
Less you are right!
