Its not new tech but you’d most likely only see this in a datacenter or buildings with 10 Gb connections as this is fiber optic cabling. One would need an SFP to actually connect it to the port however. Also the tips of the fiber were probably scratched when installing it into the vent holes so the whole cable will probably be replaced and then fixed, so there are multiple failures here.
This is what an SFP looks like.
I’m playing on Linux, endeavorOS, X11, latest proton-ge with raytracing at 4k and I’m getting a solid 45 minimum fps. I don’t experience any issues.
