The following before-and-after images are from the CryEngine. Developer Crytek uses Shader Model 3.0 techniques (vs. 1.x shaders) to add more depth and realism to the scenes. Notice the more realistic look and feel when SM 3.0 is applied to the bricks and stones that make up the staircase. In the scene featuring the Buddha, the full image comes to life with the use of SM 3.0, with the technique applied to multiple objects.
It has everything to do with Nvidia. It's their e-mail. The full image would also
come to life with a shader model 2.0 card. It's a bit misleading. It also says SM3.0
techniques, rather than just SM3.0, which I suppose means it's not really full SM3.0 either.
They should have run some benchies to show us how SM3.0 is a lot faster than SM2.0., or even how SM3.0 is faster than SM1.1, rather than whatever it was they were trying to show us with a low quality and a high quality image.
I can't figure out the point of comparing IQ the way they attempted to.
