I have tried with openSUSE 13.1 64 Bit and Wine 1.7.2.
The "outdated" GPU was an NVIDIA 8400 GS with SM4 support.

I have reduced the LOD and have disabled AA and also texture filtering.
I've got around ~23 fps in cockpit view of the last car (10.).
The GPU already supports SM4 but does not have enough power anyway to display a "simple" resolution of 1680x1050 without any image enhancement.
Btw. I have tried with nouveau and also proprietary driver of NVIDIA itself. The result with NVIDIA drivers was only around 10% better (2-3 fps).
With this GPU I don't think the result will be much better under Windows.
Software installation after core installation of Linux (KDE desktop):
- Installation of wine
- Installation of DirectX 9.0c
- Installation of LFS with the update to 0.6F2
I do not get any errors after LFS start. With a better GPU LFS work fine under linux.
