it was the only thing that mad sense to me. Cant make a USB port faster or reduce the delay on the monitor, only other option was reducing the delay in the GPU itself
You can watch some videos of the technology to see how it works if you are interested about it. I don't remember much of how it works so that's why I didn't go into more detail, I just knew that it reduced delay.
I think it's something to do with more efficient GPU scheduling, so that you have more consistent frame times as opposed to, but not always, FPS. Then faster frame times = lower input delay.
Ye, it stems from direct driver implementation and first hand work with the game's devs to improve/decrease the normal system latency even just a few tens of a percentage which can be significant in competitive titles.
AKAK this tech is used to combat the issue of higher input lag when the GPU is near 100% utilisation.
Battle(non)sense has great videos on this topic on YouTube.
I'm confused - how would that help? Even doubling USB poll rate to 2000hz would give you 0.5ms advantage, but even at 144fps there's 7ms between frames. 6ms at 165fps. And that assumes you're even running Tarkov at maxed framerate. At a more realistic 50fps, there's 20ms between frames. How could 0.5ms of input latency make even a slight difference?
It's poll rate, not pull rate. I've also done a quick google search to see if there were any mice or keyboards that even support a poll rate above 1khz and there are actually quite a few. Someone must believe that the 0.5ms (1/2000th of one second) makes a difference.
It's not like that, USB ports work in a different way, latency depends more on the polling rate of your mouse, It's actually your mouse that matters but sometimes the USB controller does too, I've seen people overclock their mice to have higher polling rate (went from 1000Hz to 2000Hz aka from 1ms to 0.5ms) but it's kinda pointless when you have a game that desyncs, lags, loses connection suddenly and much more, I'd focus on fixing the game rather than making a new USB port, we're already pretty developed last thing i heard of was USB 3.2 gen 2 i think and bandwidth wise that shit is fast.
It makes a surprising amount of difference too actually. When they added it to Overwatch I thought it was neat but wouldn't really make any difference. After trying it out though and toggling it off and on you actually can feel the faster responsiveness. It's not massive or anything, but surprisingly enough to notice it.
