Thanks to Mike and Anonymouse!
@Mickelukas, if I integrate my chess game as another performance test, will it qualify as a game then?
(The computer would play itself of course.)
One user has hit an error and nicely allowed the app to send the website an error report - so automated error reporting seems to be working correctly too. As for the exception, I think some graphics cards are giving me null graphic card name.
EDIT: It turns out that recent Nvidia cards (at least certain 7xx series) do not support the JOGL GL2 profile, causing graphics tests to fail, and causing serialization of the results to fail too (even if graphics tests aren't run). I should have a fix soon.
Operating system score card so far:
Win-64 version: 11 downloads.
Win-32 version: 1 download (me)
Linux-64 version: 0 downloads
Linux-32 version: 1 download (me)
I thought there would be a few more linuxers...
