Hello!
It seems like Vegas Pro is not utilizing the GPU. There might be a few reasons for this, but here are three important things to consider.
– First things first, make sure that your laptop is using the highest performance setting for Thunderbolt, and there are no issues with the Thunderbolt cable or port. Performance can be limited if the Thunderbolt connection is not optimal.
– Check that hardware acceleration is working properly.
To do that, go to Options > Preferences > Video tab.
Under GPU acceleration, make sure you’ve selected the option that uses your 4060. If it’s set to “Auto,” select your GPU manually to ensure Vegas is utilizing it.
– For Vegas to render the video whith hardware acceleration, you need to make sure you’re rendering using the NV encoder (NVEC) instead of Mainconcept AVC. You can change that when customizing render settings under “Encode mode”
