1000hz off sync causing lag?
« on: 03:23 AM - 02/21/20 »
So in pubg new tdm mode I tried playing with off sync while using 1000hz..

Instantly the game became a lag fest.. was not a stutter issue big turns were very choppy. And gunfights became a mess as ppl were teleporting and desyncing all over.. I've used the apex for over a year and never seen this happen.

Switching back and forth beetween default and off during the match you could clearly see the problem come and go..

So why use 1000hz if it causes ur console to lag?

This is a potential issue on Xbox One and only in a few games (PUBG being one of them), especially while chatting.

Xbox One native controller speed is 125Hz. Xbox One USB polling speed is 250Hz (the controller responds to every second tick). Xbox One hardware is capable of 1000Hz via USB, but the OS isn't expecting it, which is the likely cause of the garbled chat audio (hence why "Audio Compatibility Mode" is in XB1 STs) and dropped frames. In short, Xbox One can't keep up with XIM APEX in some games.

DualShock 4 on the other hand polls natively at 800Hz. Like Xbox One, PS4 via USB polls at 250Hz and is capable of handling 1000Hz. Given the garbled audio and lost frames don't affect PS4, it's safe to assume that both PS4 hardware and OS are built to handle 1000Hz as that allows for consistent 800Hz DS4 polling with 20% headroom for lost packets.

Long story short - set XIM APEX to 500Hz instead and the problem should resolve. There's no noticeable difference between 1 & 2ms polling rates, but 2ms is far less likely to cause problems on XB1, as well as a reduced risk of mouse jitter. It's fine to leave the mouse at 1000Hz and just change XIM APEX Response Rate.

sounds like you just need to add some smoothing, I play that game on the 1x with sync off with no problems.
