--- Comment #10 from Anton Vorobyov phoenix@mail.ru 2012-11-07 14:56:01 CST --- By the way, recently performance there improved alot, most likely by updating NVIDIA blob which turned on some 'arguable' (as it was called on Phoronix) optimization by default. I'm not sure which version it was and i'm even not 100% sure it was driver, but it fixed issue to some extent. Will investigate next week what really caused it.
