I just did (and restarted), it's no bueno:
I'm surprised something so simple can't be displayed on an "old" computer (Core i5 ultrabook from 5 years ago). And I can't update the drivers.
Can I suggest the developers to implement a "manual" mode, then? Since I can't see what the program is doing, I'd rather tell it to be precise on the first ten layers (just an example) and coarse on the rest.
