I have also the GT 630M, with latest 346.35 for Linux(though now I see that 346.47 is out), and according to my benchmark, it's not the driver, but cudaHashcat 1.33 that is operating differently. See topic below this one "oclHashcat v1.33 speed drop".
What's your test? Mine is optirun cudahashcat64 -t 32 -a 7 example0.hash ?a?a?a?a example.dict
(though I was told to replace the "example.dict" with "rockyou.dict")
