Parallel Core

Hi all,

So while reading one of the most recent updates, I looked into upgrading my RA and using the parallel core because im seeing great things out of it. I have 2 issues that I want to check and see if its me or the core itself. First one, whenever I use 4x upscale, I have to crash the emulator to exit. This only happens when upscaling is on. The second issue is the controller maps seem to be wrong for the c buttons with the 4-play. Are these core issues or am I missing something. Im using gtx 1080, core i7 8700, 32GB RAM,1TB NVME PCI-e version. Vulkan video driver, x-input driver.
