Same problem here with the GeForce 750 Ti Windforce from Gigabyte.
AE starts with a raytracing error.
Things said in the internet which did not help:
– Installing latest Java JDK
– Installing latest Nividia drivers and latest AE update
– Adding a line in the registry, which basically sets a longer delay for detecting graphics cards.
– Underclocking the graphics card.
The text file is properly edited, Premiere works like a charm with the mercury engine, just AE doesn’t want to.
Any solutions so far?
