There is no inherent accuracy with FPGA. Just like with software emulators, FPGAs must be worked on extensively in order to achieve the desired accuracy. I don't know why this myth keeps coming up. Lack of understanding that just gets repeated over and over again, eventually being accepted as fact, I guess. The accuracy you see with the Analogue products and with MiSTer are the result of hard work towards the goal of accuracy, and not an inherent feature of using an FPGA. When connected to a CRT, an FPGA solution can provide much better end-to-end latency than a software solution running on an operating system, that's certainly true, but again that's not inherent to running on an FPGA; it's inherent to running without an operating system that does display composition.

Very much true, and sorry if I didn't make it clear enough. However, there's inherent potential for the ultimate accuracy without performance penalty. That's what I meant by saying it's getting better every day. You couldn't say that about a perfectly accurate system. > FPGA solution can provide much better end-to-end latency than a software solution running on an operating system CPU based emulators can actually reach very low latency with modern beam racing techniques.
