![]() Two explanations: either Radeons are very very powerful or there is a problem somewhere. The difference was just not possible: 51 FPS for the HD 5770!!! Then I tested the demo on a Radeon HD 5770. The mesh deformation ran at about 6 FPS… ouch, OpenCL is not really efficient! On a GTX 295, the demo ran at 14 FPS. I started the development of the demo on a GeForce GTS 250 and in the first versions I used a mesh plane of 800×800 vertices (around 1.2 millions triangles). When I saw the simpleGL sample in NVIDIA OpenCL SDK, I decided to improve it by rendering a real mesh with lighting instead of a grid of flat colored vertices. The surface deformer is the first demo I coded in OpenCL.
