VideoCardz reports there's now also a Linux patch that confirms Intel's upcoming Arc Alchemist desktop GPUs will support DisplayPort 2.0. Alchemist, formerly known as DG2, is Intel's first GPU for the gaming market. It's expected to hit the market in Q1 2022.
Intel’s DisplayPort 2.0 support begins with 17 patches to the i915 kernel display driver. It is by no means full implementation of the DP2.0 standard yet. The engineers working on these patches still have a long list of things to do.At the moment, there are still no displays with DisplayPort 2.0 support. It's also unknown whether NVIDIA's next-gen GPUs will support DisplayPort 2.0.
