Shader Model 4.0 Not supported?

[JuggernautOfWar]

Well if they wanted to make everyone happy they could have released PhysX for Shader Model 2 and 3 as well Then the performance would be SLOOOW with PhysX turned on, after all PhysX is designed for DX10, even though it works with DX9. Then people would complain about the even worse FPS in this game under DX9.

Do you guys understand now?

PS. Shader Model 4 is Direct3D 10s shader, so your above statement makes no sense at all.
