VFB IPR and test resolution

Im using latest vray GPU for max 2022, Im not sure whats going on but the test resolution doesnt seem to work correctly, or I’m not doing it right. See attached video. The production render is fine, the ipr is slightly bigger and ticking test does nothing.

The test resolution function won’t affect IPR if the “Fit resolution to VFB” option (V-Ray>IPR options for CPU; V-Ray>Frame Buffer for GPU) is enabled. Disabling it should produce the desired behavior.

thanks, and sorry for the noobie question..im new to max so i appreciate it :slight_smile:
