The trade-off is higher CPU usage, but modern multi-core processors handle this with ease. For final rendering (not live play), you can further engage for even cleaner results.
The x64 architecture provided a canvas for eprdll that the older x86 architecture could never truly support: a flat, 64-bit address space where pointer arithmetic could happen without the constant anxiety of segmentation. eprdll was rewritten for x64 not to simply port it, but to exploit the expanded register set (RAX through R15). eprdll x64 high quality
This ensures the eprdll module has dedicated CPU time for its oversampling and interpolation routines. The trade-off is higher CPU usage, but modern
