Oh, that what you meant, lol.
Unfortunately, VSFilter, xy-VSFilter, XySubFilter, and even Libass are all essentially single-threaded subtitle renderers. They will never utilize more than a single CPU core. If you provide a sample script(s) which bottleneck your CPU, we could look into possible optimizations. Otherwise my only recommendation to is to buy Intel the next time you upgrade you PC. When it comes to subtitle rendering, single-thread IPC is king.
I'd also recommend to try setting the madVR CPU queue to much higher value like 64 or even the maximum 128, and see if its enough to get you through these difficult subtitle sections.
