What improvements in latency reduction would most benefit competitive gaming on PC Gaming handheld devices?

[killamch89]

I’ve been diving into PC gaming handhelds lately and I keep running into latency issues from Bluetooth controller lag to screen response times. I’m curious: what specific latency improvements would you prioritize to make competitive play truly viable on these devices? Would a high-refresh-rate display be the biggest game‑changer, or is ultra‑low‑latency wireless communication more critical? Perhaps faster USB‑C polling, optimized Linux kernels, or even dedicated latency‑reduction hardware?
