AE 2017 and Colorista III and IV crashing

[Silicon Pixel]

Anyone else using Red Giant Colorista II or IV with AE 2017?

Every time I try to use the guided color in IV it crashes AE at the contrast stage (Don't plan on using guided but was giving it a go).

More importantly, when I drag the numbers for anything - contrast, saturation etc, Windows stops responding for around 15-20 seconds and then starts responding again. Happens every time I try and drag a setting.

Anyone else seen this?

Solved!

It was a slightly older version of nVidia drivers - updated to the very latest and the issue seems to have gone away. It was also happening in other Adobe effects too like Lumetri.

I guess it's something to do with an incompatibility in an older driver with GPU accelerated effects. Weird though.

Card is GTX 980 and current drivers are 375.70 Windows 10 64bit
