I get better performance in Ubuntu 18.04 vs Win7. In Ubuntu, hashcat chooses different -n -u -T values ant it works faster 8-11% on few tested hashes. I tried forcing these values in Win7 but I get same (low) result. Card is EVGA GTX1080 Classified. Both OS on stock clock. There is difference in driver version (Win7 442.19 / Ubuntu 418.43) and cuda versions (10.2 vs 10.1). Still, in Win7 using latest drivers. Wiki implies no difference in speed between OS's, but in my case I just can't make it work on the same level as in Ubuntu. Can anyone confirm this on any Linux distro?
