Substance Painter - Discussions - GPU often stays at idle clocks while iray rendering?

This has been happening to me since 2.5.0 released. Prior to that my iray renders were fast and worked every time, but since 2.5.0, easily 95% of the time I click the Render button, iray isn't really "kicking in" my GPU and the clock speeds sit at their idle 135mhz core/405mhz memory and GPU usage with spike at a whole 6% and the render is so slow it's about 1 iteration every 45 seconds. It doesn't happen 100% of the time, maybe once every 20 renders it will kick up to full speed, 100% utilization and render hundreds of times faster.
And yes, I do have CPU disabled in the options.
