Hi!
Previously when I had rubbish AMD processor and when I was exporting videos there was enabled GPU Acceleration in conversion. Now I have i5 with the same GPU as previously and now I don't have GPU Acceleration when exporting. Now exporting is much slower than before. I didn't change my graphic card, so whats the problem?
My spec:
i5-4670k
gtx 660 ti
msi z87-g43
12gb ram
win7
edit:I found the solution for this. Don't update your Nvidia drivers to 340.52. CUDA will stop working with Action when you update. With 337.88 CUDA and GPU acceleration works great.
