2000hz doesn't work on the mouse

I would have posted the same before but recently when experimenting / since I got 4k mouse I actually do feel a difference but not in latency or click speed but in visual motion.

Somehow higher Hz provide smoother experience almost like higher FPS. I don't know why but that is the case.

E.g. with my VXE R1 PRO I sometimes forget to switch it to 1k (default for Apex) from 125 which I use on daily basis to save battery life and in case of 125 Apex actually becomes jittery in terms of visuals. Theoretically CPU should have less load be able to process more but in reality it almost stutters on low hertz. Same goes with Aimlabs, it is basically unplayable and for me only 500-1000 Hz range is usable given Aimlabs does not officially support anything above 1k and that aligns with my experience of it crashing my PC if I play on 2k-4k for extensive periods of time.

So yeah I don't understand why above mentioned happens but it does, same as many reported opposite extreme = jitters / stutters when playing on 8k Hz even on super top end hardware.

Finally it is kinda "stupid" to leave performance on a table so to say - if you have a mouse that can do 2+k Hz why not use it even if you can't tell the difference. Assuming that you don't lose performance elsewhere ... Problem is that Apex has not gone on record as far as I know regarding how high Hz it supports and clearly it is the problem as in other games it is more clear cut - either you can play it or as e.g. in Valorant support says that 2k Hz is max game supports at the moment, after you will probably and in my practice actually get stutters.

p.s. all in all gaming mice are gimmicks, marketing tricks as I recently discovered topic of DPI and software interpolation which if you read about it explains why people like Donk who is basically godlike aimer uses 400 dpi. People from youtube like Optimum has I think in a way mislead us towards hardware maxing for not the best reasons. And for sure those 20000 DPI and 8k Hz are meant for if not none actually to benefit then at best only top aimers would. The rest are still fine with 400-1600 dpi depending on sensor and 1k Hz pooling rate shape of the mouse being the most that will give you improvement in accuracy.

Guys, you can't feel the difference between 1000Hz and 2000Hz. For example, 1000Hz refreshes every 1 millisecond, and 2000Hz every 0.5ms.

If we take into consideration that a monitor with a refresh rate of 240Hz makes updates of your image every 4ms, and you set your mouse to 2000Hz, the mouse updates every 0.5 ms, the monitor may not display those updates until the next refresh. The only way you can slightly see any difference is if you get a monitor with a 540Hz refresh rate. 

Since I got VXE R1 PRO this year I can't run it past 1k in stable way. 2k even 4k works but it seems to be contributing to game crashing (directx error stating bla bla bla about stuff but no matter what you it still crashes).

Also my potato system from 2019 can't handle both Apex and 4k hertz I guess because of micro stutters.

If you on similarly outdated system please post your specs, really eager to see what can handle 2k :)

Where did you get that information? Mine works perfectly.
