Horrible performance in maya material editor Tweet

[pirate17]

I have demo version of octane, it's basically unusable. Not only the refresh doesn't work correctly, but also the performance is horrible. THe processor run up to 60%, just by changing the noise otaves... I don't think it's normal, especially that i tried the demo for 3ds max, and there it does work correctly, except the texture set's doesn't work at all. What is going on? The gpu is gtx 970, but as i said, it's not the problem, because on the other software it does work.
