On Cudaminer.... the hash rates on scrypt jane nf are lower on windows 8 by 33%. My vista computer gets about 3.6 mh/s and my 2 windows 8 computers get 2.3 mh/s. I tried everything I could even compiling Cudaminer on windows 8. All the combinations of the arguments ect.
people still mine that? I took a look at the AMD kernel - looks like it could use some work.
My vista computer gets about 3.6 mh/s and my 2 windows 8 computers get 2.3 mh/s. I worked on it on and off for months. Still only 2.3

I think I found the problem. The source code is 32 bit and I can't compile it to x86.

lulwat ? the source code isn't anything ....

ok just replace every uint32_t by uint64_t
try to retune cudaminer (however it is a known problem)
No problem.

At this point, im ready to load vista on my asrock 81

From what I have read the hash is normal on all os except windows 7 and 8. What is it about windows 8 that one cant get 3.6 mh/s. money flying out the window.

Edit: anybody have any thoughts way please.
why not just staying with vista... (or you instal vista on a secondary partition where you can boot if needed) ? (since it doesn't seem to be a problem for you... also if you look back a few solution was given by bathrobehero, don't know if it works, but you can try... may or may not work since it is more likely dure to how windows8 manage vram...)
