I just upgraded two computers with new MSI RX 570 video cards. I'm using VEGAS Movie Studio 16 Platinum with Windows 7 Home 64 bit edition. My systems hve 16GB of memory. I have watched video's on Youtube about setting the Movie studio software to render using the GPU but, it makes no difference. GPU is just hovering close to 0% and the processor is going to 97-100%. I have created a RAM drive with AMD software but makes no difference. I have the latest AMD drivers for the video card which is 20.4.1. Power setting is "High Performance". If I run a GPU test with GPU-Z or other, the GPU constantly gets up to and stays close to 100%. Not sure what else to try!
