I was able to compile it in VS2012 Professional and actually run it on my puny Quadro 4000 (Fermi based) and tested it for scrypt-jane. I Could run it with -l F4x3 and received a fairly low 0.41 khash/s. Sadly interactive mode didn't seem to work, so I can't use it on this computer (I use it for normal work too).
The order in which I will enable interactive mode is Titan, Fermi. I also noticed terrible hash rates running Fermi scrypt-jane on Windows. Even on GPUs that otherwise work really well for scrypt hashing.
Generally I get much better results on Linux. Likely Windows (the WDDM driver model) has a performance problem when allocating a lot of GPU memory... I haven't been able to try Fermi devices under Linux yet.
Yesterday I tried to escape the texture cache size limit (2GB) by splitting up the data into two textures. Didn't work at reasonable speed unfortunately, so I dropped the idea.
