I seem to be getting better results out of the cmd window I have selected by about 1mh per card. I've split 2 750ti per .bat file and I get roughly 22.5 mh out of the non-active window and about 24.5 mh out of the active window. If I select the other one, the performance flip flops.

This is on win 8.1 x64

(what does mean "non active"/"active" windows) ?

which ever window i have selected would be the 'active' window. I've got 3 total running but only one can be the actively selected window. In total i've got 4 750 tis and a 660 gtx, so i'm running 2 instances of ccminer35 and one of ccminer30.

I can combine them all and I get roughly 55mh but I left that on over night and I crashed at some point in the middle of the night so I decided to split them up this morning.

Try adding this to your bat file:

Code:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
(your start command)

Maybe it fixes the problem.

yes it will work... but only once cudaminer has been translated to opencl (assuming it really work at all...)
