Um, I'm using MBA mid-2011 with 1.7GHz i5. Should be able to run it (One of my friends using PC could play that with Intel HD Graphics 2000 at it's lowest settings). I created a Key in regedit so I stopped getting Vertex Buffer size error, but now it always shows 'failed to lock vertex buffer in CMeshDX8::LockVertexBuffer' when I try to start watching a replay. How to solve this?
