I recently purchased a Dell G7 7500 with a Nvidia RTX 2070 video card. As a test I just created a project with a single MP4 file (8mbps, 1080p) and Exported the project with Automatic Settings (i.e. 1080p). Watching the Task Manager I can see sometimes Premeire Rush will only use the RTX GPU @ 100% utilization and completes the export in about 4 minutes. Other times Premeire Rush will use the Integrated GPU @ 75% utilization and the RTX GPU @ 35% utilization and the Export takes about 12 minutes. I have Adobe Premiere Rush set to High-performance Nvidia processor in the Nvidia Control Panel. I have not found a pattern on when Premiere Rush will use just the RTX GPU or both GPUs. Any ideas on how to make it only use the RTX GPU?
