Desync/Input Delay/EMI/RFI/ or whatever it is

Separate area for niche lag issues including unexpected causes and/or electromagnetic interference (ECC = retransmits = lag). Interference (EMI, EMF) of all kinds (wired, wireless, external, internal, environment, bad component) can cause error-correction latencies like a bad modem connection. Troubleshooting may require university degree. Your lag issue is likely not EMI. Please read this before entering sub-forum.

I don’t know about you, but to me personally, it feels like the more powerful the hardware, the worse the problem gets.
I agree this part. This problem coming with no solution idk maybe one day someone fix this.
There's many reasons for this

- Faster hardware lifts the fog (less motion blur, less stutter, more framerate) that lifts the fog that hides latency issues. So you've got a whac-a-mole of weak links.

- That's why 3200dpi+ 2000Hz+ mice feels better on a 480Hz 480fps OLED, but doesn't really help old 60fps games on 1080p LCDs.

- That's also why 60fps looks more stuttery on OLED than LCD (explanation why)

- That's also why you feel internet latency issues more with modern 300fps FPS gaming than 60fps FPS gaming. The high framerates reduce stutters/blurring/etc to the point where you see ever tinier and tinier latency problems.

- And yes, electrical (Shannon-Hartley Theorem related issues): Pushing limits on your speed/limits/CPU/GPU/etc can create things like thermal throttling or error correction (e.g. GDDR6 error correction memory or PCIe error correction), that adds latency. Pushing limits pushes us closer to Shannon-Hartley Theorem on noise theory of digital transmissions (whether a phone line, network line, fiber optic line, PCIe lane, USB cable, etc), creating more need for error correction layers, which has now been added to modern specifications of USB, of newer DisplayPort, of newer PCIe, of newer Ethernet, etc. All of which adds various latencies in all sorts of unexpected places.

Essentially...

We've pushed Moore's Law to the limits, and we're suffering various consequences that are mostly unfixable without dramatic upgrades/mitigations. Sometimes a few of the problems are fixed by intentional throttling (e.g. capping the framerate surges, underclocking slightly to prevent thermal throttling, intentional ping latency to slow down FTTH to DSL latencies in order to avoid getting server-side LPB handicapping, using a paid gaming VPN to bypass inferior local servers despite higher latencies, etc) to make things feel more consistent without latency yo-yo effects.

But often, we misdiagnose this, because for fixing 1 problem (turn 60fps to 480fps), we create 10-100 additional problems (since there's no longer a 60fps veil to hide harder-to-feel issues), that often is a hassle to fix.
