Fusion keeps "loosing" my Nvidia cards as it runs...

When I open it and go into the OpenCL pref's everything is fine....
But as soon as I execute an OpenCL tool.....suddenly FU cant find my openCL cards anymore
(kinda like kids when chores happen)


I have 4GPu's installed and never had this issue in previous FU versions

some tools....like LUT cube creator will not create any pixels until OpenCL is unchecked

(kinda like kids when chores happen)

What a brilliant analogy! I totally agree...

But back to Fusion...
Could it be that you're running some other OGL-hungry App in the background?
In the past there was a rare issue with Skype(!) chewing up your GraCa's performance....

Cheers.

I'll see what I can find...

Thanks for the tip

Disabled all extraneous applications...reinstalled drivers. No luck so far

Just to be clear...openCL is fine on FU 6.4 and 7....just not FU 7.6 studio

it appears it is related to the red R3D importer...

If I start a blank fusion interface...all runs fine, all openCL tools run like normal.

As soon as I open a r3d file I get:
OpenCL clFinish failed: CL_INVALID_COMMAND_QUEUE

If I uncheck 'use openCL' in the r3d import settings all runs fine.

Just did a complete re-install of Fusion with no change.

Hi Mike.

Thanks for investigating!

I was able to reproduce the issue and logged it as a bug.

Cheers.

Eric.

awesome Eric....

It's nice to have a issue that isn't just in my machine.
