Does Mousetester/LatencyMon respond to emi?

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.

Does Mousetester/LatencyMon respond to emi?

No matter how much i optimize my system, try different usb ports etc. my graphs are always the same.

It's not the best way to measure it.
Best would be to get a high speed camera and record it on a high hz monitor, but that's expensive and time consuming.
You could also try it with "feeling it" but you'd need to have good experience with not just using a mouse, but using it when it worked perfectly.

The ferrite beads on the mouse cable should be able to reduce or mitigate electrical interference.

As for the graph there are many tin foil hat tweakers that say that tweaking your OS can improve mousetester graphs but it's not true (unless you suffer from timing issues that desync readings, in this case make sure to disable HPET in OS and enable it in Bios + use ISLC when running mousetester graphs).

The main thing that matters is firmware optimizations, some mouse developers implement buffers to make mousetester graphs look less jittery, some others implement MotionSync to sync SPI with USB Polling events, the latter is more efficient in making the graph look better but it comes with an input lag reduction/penalty (depending on the implementation, MS reduces input lag with Razer's implementation but it does increase lag by around 1ms in 3370 implementations such as the Xm1r, GM41, Prime Wireless,..).

idk about LatencyMon.

(not necessarily based on mousetester and lmon) Do you know of any signs that i could look for that might speak for emi? Because I've tried pretty much everything I could find after about a year and a half of googleing and troubleshooting and i'm just out of ideas on how to fix my inputlag :/

If you're worried about actual input latency just acquire a good CRT & razer 8kz mouse & 8khz keyboard. Make sure you use interrupt affinity policy tool to assign cores to each usb hub. This is probably fix all your problems. The issues your facing could basically be compensated for by doing that. No matter how much EMI reduction or tweaks you do it won't be enough. Interference will always occur even in lab environments. Hence why quantum computers are so hard to make! They have to use some sort of error correcting in them just like computers. Playing in the AM is noticeably smoother/responsive though probably due to cleaner electricity.

EMI are extremely hard to detect, Imo when you get the feeling of input lag there's 1 faulty piece of hardware in your setup, in my case it was a mouse that was supposed to be extremely low latency but ended up suffering from massive click latency inconsistencies.

I downgraded to a mouse with a worse sensor and worse click latency (according to different reviewers) and now my issue is gone.

If I was you I'd try to play with different setups, wether it's a mouse/mousepad/keyboard/monitor/... and see if you find any improvement.

The viper 8khz that was recommended by another user has MotionSync up to 4000hz that will make the mouse graph look flawless so if the issue that you are having is caused by sensor jitters it will completely fix it.

I'm pretty sure I ruled out any hardware issues :/

Cathode Ray Tube, AKA box tv's/monitors. Or a high end display like the 390hz acer.
