Hi there!
I recently bought a RX 580 (8GB) to replace my old GTX 750Ti. I have a upcoming video that I wanted to start working on but the program crashes now on boot. It starts up fine and when it gets to the GPU Acceleration the crash reporter pops up. I bought my copy of Vegas during a Humble Bundle if that helps. and my specs are pretty modest:
Ryzen 1600 CPU
RX 580 (8GB)
8GB of RAM clocked at 3200Mhz
Windows 10
I did manage to get in to it by doing the Shift+Control Boot and when i looked into the GPU Acceleration options it had two of the the GPU in it which i found to be rather odd. I have tried turning it off completely but it seems to turn itself back on when i restart Vegas. another thing to note is i have totally reinstalled the program twice and i have had no luck.
Im not too sure what to do here cause i really wanna see what ReLive can do for me compared to OBS and Shadowplay but it's hard to really test it out when i cant even edit the raw footage :(
