Can you post your specs, especially your GPU?

Currently the required / recommended specs are quite high as we did zero extra optimization (except engine optimization - whcih we just did not touch).
We would recommend the following specs (not final or complete):
+ 8GB RAM ( Game currently just uses 500 MB as we profiled it)
+ 2,4 GHz Quad
+ NVidia 960 GTX - 2 GB VRAM ( this is probably the issue we currently have - as all textures, meshs etc. are loaded at once )
