Problem summary
Using Geo-Channels can cause a drop in performance
This issue affects color-managed projects that are not using the nuke-default config.
Customer reported version
Mari 4.7v2
Customer reported platform
Multiple
Steps to reproduce
1) Create an ACES project
2) Import a Geo-Channel map to the Object
3) Create a Geo-Channel Node and select the imported map in the Channels property
4) Create a Scalar Paint Node and import the same map used for the Geo-Channel
5) Orbit the Object and view both the Geo-Channel and Paint Nodes to compare performance
