-Always limit your fps, preferably to a number which will not leave you in a GPU bound situation, being in a constant GPU bottleneck will introduce additional inputlag. Ideally you should aim for stable fps twice as much as your refresh rate.

It's good to limit your fps, but there's nothing wrong with being GPU bound, that's where you want to be. You don't want to be CPU bound, this is where input latency happens as your CPU will become backlogged with interrupts if CPU bound. As for the GPU, being GPU bound doesn't have a negative effect because it's only task is to generate frames, where the CPU handles a lot more unique tasks.

Also the mouse polling thing. 1000hz is enough. Windows handles interrupts at 1ms, and 0.5ms if you've modified your timer resolution. 1000hz is 1ms and 2000hz is 0.5ms. 8000hz in theory should be beneficial if current operating systems can handle it, but they can't, so it kind of is snake oil but not really. And it's not a game issue, it's an operating system issue. Your mouse would be generating more mouse reports than the Operating System can handle, so it gets backlogged and then that's where input latency happens.

And using a normal windows install is fine. Your suggestion is overkill. It's like saying, I have 20 apps on my computer, only 1 affects input latency, the solution is to not use the 20 apps at all. Yes windows does have some services and apps that affect input latency, but those are very few and can be solved by just closing or uninstalling/disabling it.

Do not modify the timer resolution for games and again, I'll have to be the one to advocate for 8k every time, there is no reason against using it unless a specific game has problems. AFAIK timer res and polling rate have nothing to do with each other but even if we look at a theoretical situation, you can make the timer resolution as low as you like but it's a complicated solution.

I suggest you do a bit more research on the relationship of timer resolution and how windows handles mouse interrupts. How you seem to think it works it incorrect. And no, polling rate issues isn't a game problem, it's an operating system problem. If a game doesn't perform well with 8k polling rate, it's because it's CPU bound.

I suck balls in cs but holy shit this must be one of the lowest input lag machine on this forum and i guess there is still room for improvement since i haven't done advanaced tweaks like at all.

Welcome to the club of people who keep repeating their famous one liner until they get bored of it. This mindset of advanced tweaks is just wrong. You have a system, there are metrics and also subjective feel that will decide what is the best. Personally I have pretty bad lag and desync in games but otherwise have hardware that can almost be called legacy at this point that can be tweaked to the high heavens. I wouldn't switch from this experience to one with less desync but also less optimizations.
