Intel HD 4600 stuck at compiling shaders

Unfortunately I received faulty k610m card, but managed to get my hands on Radeon HD 7650A, which is the default MXM video card that this HP machine is being offered as when was new. So the OpenGL issue is no more, I am able to run games on latest version of the emulator. However, this card does not support Vulkan, so my question is: how important is Vulkan for PS3 emulation? Would there be titles that would ONLY run on Vulkan vs. OpenGL? Or all games should be playable on both, but performance would be the differentiating factor?

P.S. If there is a modded VBIOS or modded drivers for Radeon HD 7650A, I would appreciate any help. I read here (https://www.amd.com/en/technologies/vulkan) that Vulkan is supported on HD 7730 and up, so maybe there is a hack for 76xx series?

Thanks!
