Re: OpenCL acceleration on Macbook Pro with Certified card is BAD

Just ran CS6 with gpu mode on my 17" and now was able to go for a good 2 hours without the performance dropping. I wasn't adding filters this time and was mostly cutting with a bit of audio EQ and a few dissolves. I stopped editing and the gpu was still going strong. I'm now thinking it wasn't so much a failure after X amount of time but a failure due to some odd combination of filters or just the gpu portion crashing randomly. In fact in almost every situation I was tinkering with gpu effects such as 3 way CC. It doesn't always do it and today was messing around with CC for 45 minutes and didn't kill the gpu. Then the next time the gpu dies after 30 minutes of minor use.

At this time I'm thinking it is more of a random crash of the gpu portion of the application when the gpu effects are being adjusted. It doesn't always happen but that seems to be when it can happen.

Overall I am very happy with the gpu performance in CS6 and look forward to when these gpu crashes can be fixed. For now I have a solid workflow.

use gpu until the gpu mode gives out. Then either switch to cpu mode or restart CS6. If it gets too annoying I can just use cpu for now. It also seems like I may be able to use gpu for most of my cutting and minor assemble of my projects and can expect the gpu to only have problems once I start getting into heavy CC. I do most of my heavy effects work in AE anyway so CC seems to be the only area where I could run into problems.

I do look forward to a fix in the future however and I know eventually we will get there. As a developer myself I totally understand how hard it is to shift gears and start with a new technology and try to bring it up to the same level of performance as the existing technology.
