Intel Sandy Bridge on Linux was slightly slower than the Windows driver performance while under Ivy Bridge this Linux configuration was slightly faster than Windows 7 for OpenArena 0.8.8. Using Unity/Compiz on Ubuntu 12.10 continued to deliver much lower frame-rates than with KDE and at a much greater disadvantage compared to Windows for both Intel graphics generations.
For Unigine Heaven there is just the Windows 7 numbers since the Intel Linux support for this more demanding game engine isn't in great shape on Mesa.
