A follow up:

I have just tried to minimize the number of used registers by -ta=maxregcount:10. However, according to the NVIDIA visual profiler did nothing Change. Is the flag still working?

I'm assuming you mean "-ta=nvidia,maxregcount:10". All the "maxregcount" sub-option does is set the ptxas "-maxrregcount" option and that does appear to be working. Why ptxas wouldn't honor this value, I'm not sure.
