After updating GPU, movies are shown dark while editing


When NVIDIA GeForce driver was updated to the latest 340.52,
movies are shown dark while editing.
Also, you may not find CUDA options.


The problem cause is under investigation. (as of August 1, 2014)

Please go to
and roll it back to the previous version 340.43, 337.88, etc. in the mean time.

Update: March 16, 2015
LoiLoScope2.5.4.2 is ready to fix this problem.

Note: You may see slightly higher CPU usage with this version, so it is highly recommended this to be used for NVIDIA users only.
