Open GL is cross platform you can use it on every thing except the 360 it's a great way to go multi platform. more devs should use open gl

Yeah I agree it's very portable and a great technology in general. Though I've seen more indie 3D games use this technology than AAA games.

DX 11 is much more demanding than DX 9,because of tesselation.

Tesselation:

http://en.wikipedia.org/wiki/Tesselation

Tesselation multiplies the load in the graphics card.its a totally different world. You wont see squyared edges in the graphics,the will be molded and curve.

DX11 should run better then DX9 but it aslo has more advanced option like Tessellation which will hinder performance. Visual side in a game you cant tell much difference but if you compare a DX11 game with a DX9 game there is a lot of difference.

Open GL had tesselation 3 years before DX

The tesselation technology that Microsoft is heavily promoting for DirectX 11 has been an OpenGL extension for three years. It has even been possible for years before that, using fast instancing and vertex-texture-fetch.

Well dx10 is supposed to offer better image quality than dx9, and dx11 is supposed to add better performance than dx10 including better graphics.

Only thing that springs to my mind is that dx11 offers softer dynamic shadows which can cause a drop in fps. TBH though I'm unsure why you have such low fps :/ As a previous user said... dx11 is supposed to offer better performance.

Doesn't matter if the the the programming supports it if the hardware isn't there to process the APIs in efficient way.
