I'm curious about the effects of the added physical distance with a PCIe extension like that. Presumably it adds a tiny bit of latency across the wire. At what point does it become an issue?
The latency isn't an issue, the timing becomes an issue because you don't have a clean signal at some point, meaning the signal will arrive "spread out" over time. If it spreads to the next signal, your GPU isn't recognized anymore.
But as long as.that doesn't happen, there is no latency or performance decrease.
