  It doesn't look like it.  But given that official nvidia docs say GT730 is not supported was 525 drivers, might not be surprising it doesn't work particularly well.  It is possible that some parts that it needs to work well have been removed or otherwise no longer trigger.

  It might also just mean that in some future version of that series of drivers, support will be fully removed, and right now is on borrowed time.  I don't know if nvidia does this, but some companies don't like to drop support except in major releases (it would otherwise be annoying to update from say 525 to 530 and find devices stop working, but more reasonable to expect that from 5xx version to 6xx version)
