Latest drivers (NVidia and ATI)
M_M:
266.58 WHQL drivers are out...
Btw, does anyone know how come that GTX460 is compute capability 2.1, and newer few month newer GTX570/GTX580 only compute capability 2.0? Is nVidia going backwards???
msattler:
Any benefit noticed in anything beyond 260.63?
My rigs are thumping along nicely on 260.63 and 260.99, except of course the rigs with Win2K, which I think stopped being supported at 257.21.

Compute capability mainly differentiates 2 things, The instruction set & compute geometry. Although they have the same instructions, 2.1 as used in the 460 is different to the cuda core configuration used in the 470/480/570/580 , which is 2.0. Basically the 460 has extra warp schedulers & a few minor differences, while 2.0 covered the complete original Fermi design.

I noticed a small speed improvement somewhere around 263, but since then it has mostly been adding support for new cards.

Okee dokey.......
Off for another round of updates then.
Thanks, Jason.
