Lots of games do lag compensation. What you’re trying to do is get under their lag compensation wire, where they’ll do what’s possible to keep everything fair for everyone and you.
Someone already said to shoot for Singapore remote servers. That’s a good start. Make sure you have qsv or your computers equivalent of it to decode video quickly. The decoding time adds to your input lag because you can’t see the stream until it gets decoded for you.
Someone already said to look into the Chinese bizarro mobo/cpu combos built off of excess chips, prototypes and factory seconds. Bear in mind that support for these is nonexistent unless you read Chinese and sparse at best there. Bear in mind that a lot of the time the CPUs are soldered to the board so you can’t upgrade and have to be a little more careful when installing a heatsink. If you’ve been in the game long enough to pull a bare motherboard out of a dumpster and fiddle around with it until it works then the aliexpress computer pipeline might be a good one for you.
Check out the Chinese video cards too.
I have an alternative set of solutions though, and they’ve worked well so far:
Turn down the resolution. It makes a huge difference. Turn down the texture quality and post processing.
Alternately, stop playing new games. They’re so bad.
If you don’t want to turn down the music or stop listening to it, give the intel b series a look. They’re competent at 1440 and cost a fraction of what nvidia cards cost.
