I'm waiting for a cuda update, the edit section seems a little bit slow now that I've tried it better.
As for the software there're a few bugs, the more important is that sometimes every color option stay stucked and nothing change, only the raw pannel options works. I can't say the exact path to reproduce this but it happens to me different times, it's boring to close and reopen the application.
edit: and I'm expierencing frequent GPU panic that freeze the computer and then make it restart, this needs to be fix.
