Hello R-Typer
On my new cab i´m using a Radeon 7450 (has 3 ports, vga, hdmi, dvi) on dvi port i couln´t have 15khz, only on vga, i already patched with 15khz, and i can confirm that on this card Bios works fine thru vga port.
So when i saw this post about those modified drivers, i was very exited, because some cores on retroarch people said that works better with vulkan, i just install a quick fix that i saw on that youtube channel , but seems that has no impact on performance doing that.
So that caucth my interest in test this new updated driver, with updated vulkan support.
Thanks Marcos
