Are DisplayPort 2.1 cables backward compatible?

Yes, fully. A DP 2.1 cable works with DP 1.4, 1.2, and 1.0 devices. It just won't achieve DP 2.1 speeds unless both the source and display support it.

Should I choose DisplayPort or HDMI for gaming?

DisplayPort is preferred for PC gaming due to higher bandwidth, adaptive sync support, and daisy-chain capability. HDMI is better for living room setups connecting to TVs.
