SpeedGrade CS6 and CC AppCrash analysis needed

Question

Hello,
Last week I was fighting through repeated SpeedGrade crashes when trying to apply a custom-saved Look to a Grading layer. A single click or attempt to move the layer immediately generated a crash.
I thought that my machine was hitting 100% usage, but task manager never showed that to be the case. I re-opened the project several times, even tried a new project and could not do a single thing with the layer before the program crashed.
I dumped all the temp files, upgraded to CC, and same thing. Finally, I believe I trashed preferences and deleted all my local CrashDump files and managed to get through the project and export without any further crashes.
Trying to find out if this is a common occurance and if there's any tips/tricks to alleviate crashes similar to this.
Thank you.

Answer 1

Thank you for sending the .look files. We'll have a look at them.
According to your forum post you have the following machine specs:
Windows 7, 64-bit
AMD Phenom II X4 965 3.4GHz
16GB RAM
NVIDIA GeForce GT 440
What exact computer model (laptop/workstation) is it ?
If it's a laptop it's possible that default graphics settings has to be changed.
Please try the following:
- Open nvidia control panel
- Check which settings was applied to Speedgrade
If the setting was set to 'integrated' chosse 'use Nvidia card' (high performance) instead
Hope this helps.
