I posted a 2013-12-07 version. Most notable difference is that the Fermi kernel now targets the Compute 2.0 architecture explicitly. Expect maybe a very small boost in hash rates. For me it went up from 228->235 with the cudaminer x64 version for my Compute 2.0 card.
I'm using GTX480s and I just tried the latest build:
- previous build with
K15x16 - 246 KH/s
- current build with
F15x16 - ~220 KH/s
- current build with
K15x16 - says it requires 3.0 and doesn't validate
other config: -c 0, -i 0, it is second card, so I use the interactive on the other one.
During the last few days I tried using Fxx*xx on both GTX480 and GTX570 and I always get much lower khs compared to using Kxx*xx
I have also noticed a drop in performance since switching to the ulong2 method in fermi. Most noticable in x64. Also, this maybe of no concern of yours as you don't really support cuda 5.5 but, the spinlock kernel crashes the cuda 5.5 cicc compiler when compiling for compute 3.0.
