I have an AMD, though it’s an RX 590. Though I have no idea if that’s “Radeon” or not. What I do know is Flycast is, let’s say quirky, with the video drivers sometimes.
- What video driver are you running RA in?
- Are you using DC BIOS or the HLE BIOS?
- Have you tried the other BIOS that you are ‘not’ using yet?
- Also, are you on the latest stable RA? 1.9.1, I believe.
I know when I use Vulkan, I can’t get the Sonic Team video on Dreamcast to display. When I used the old OpenGL I had to set a hardware context setting to get any video. I feel like I also had crashing issues at some point, but I’ve re-setup RA so many times over the last several years who can remember what caused what.
For what’s it’s worth, currently I run GLCore and I think that takes care of the hardware context setting on it’s own now. I’d have to double check that, that’s pretty recent.
