Neverness to Everness — Mouse input lag only in fullscreen

Every guide I can find skips the part I am actually stuck on. My results were consistent across three attempts, so I do not think it was luck.

My results were consistent across three attempts, so I do not think it was luck. Thanks in advance to anyone who chips in.

Worth checking first: the wiki number is theoretical; real results are always a bit lower.

Depends on your setup, but broadly ignore the loudest advice; the boring answer is usually the correct one here.

Worth a shot before anything drastic.

Agreed on most of this, except temperature is the usual culprit when performance degrades over a session.

Had the exact same issue. the wiki number is theoretical; real results are always a bit lower.

Others may have a cleaner method.

From experience, measure before and after, otherwise you are just guessing whether it helped.

For what it is worth, verify the files before anything else; it catches more problems than people expect.

Same boat here. do the cheap diagnostic first — it costs nothing and rules out half the causes.

This comes up a lot, so: it is almost always a setting rather than hardware, so try the free fixes before spending anything.

Let us know which part worked.

I went through this last month. ignore the loudest advice; the boring answer is usually the correct one here.

Report back once you have tried it.

Not the answer you want, but it depends heavily on your specific setup, so take any single number with a grain of salt.

Adding to the above: the community guide covers this better than I can, but the summary is to prioritise the basics first.

That fixed it for me, at least.

Speaking as someone who got it wrong initially, the community guide covers this better than I can, but the summary is to prioritise the basics first.

Report back once you have tried it.

Quick correction to the above: verify the files before anything else; it catches more problems than people expect.

Only partly related, but the trick is to change one thing at a time and actually note the result before touching anything else.

Worth checking first: give it a clean reinstall before assuming the hardware is at fault.

This is the bit people miss — the defaults are conservative on purpose, so there is usually headroom to gain.
