I am having exactly the same issue……

I am also running a NVIDIA GeForce 7300 GT graphics card. I’ve tested an uncompressed 1080 QT (10 bit) in a uncompressed timeline to rule out the ProRes issue and I’m still getting the same errors. “the effect ‘overdrive’ (etc.) cannot be rendered in a sequence of this size with the current graphics card.”

If I change the sequence to 8 bit – then the issue goes away…. So colour depth and resolution combined seem too much for the card.

Any takers???????
