Usb 2.0 has a latency of about 125 microseconds. Unlike 2.0, usb 3.0 is not a shared-bus system. Instead it uses a point-to-point link between the host and each device which can help decrease the latency by a significant amount (in terms of multiples, still not noticeable at all).
In USB 2.0 the polling interval was 0.125ms, so the best possible latency for the host to read some data from the device was 0.125ms. I'm hoping for reduced latency in USB 3.0 devices, but I'm finding it hard to learn what the minimum latency is.
15 sty 2018 · USB 3.1 = 10 Gbit/s; eSATA = Up to 6 Gbit/s (750 MB/s) right now as it depend on the internal SATA chip. Thunderbolt = 10 Gbit/s × 2 (2 channels) Thunderbolt 2 = 20 Gbit/s; Thunderbolt 3 = 40 Gbit/s; In Bytes per second, that is: USB 1.1 = 1.5 MB/s; FireWire 400 = 50 MB/s; USB 2.0 = 60 MB/s; FireWire 800 = 100 MB/s; USB 3.0 = 625 MB/s; USB 3.1 ...
20 lis 2019 · For example: USB 3.1 has a minimum bus interval of 125 μs, so the theoretical maximum polling rate is 8000 Hz. Here's what I could find: USB 1.1 and 2.0 - Low Speed. Max Polling Rate: 125 Hz. USB 2.0 - Full Speed. Max Polling Rate: 1000 Hz. USB 2.0 - High Speed, USB 3.0, and USB 3.1. Max Polling Rate: 8000 Hz
19 gru 2023 · USB 2.0 delivers power up to 500mA at 5V. USB 3.0, on the other hand, enhances power delivery, offering up to 900mA at 5V for unconfigured devices and up to 1.5A for configured devices. This improvement caters to power-hungry devices and faster charging.
USB 2.0 Full-speed uses 1ms interval. >99% of USB mice use USB 2.0 Full-speed connection. USB 2.0 High-speed uses 0.125ms interval, which is the same as USB 3.x. I know less than 10 mice that utilize USB 2.0 High-speed connection and 0 mice that use USB 3.x.
The Minecraft server (including single-player, as single-player worlds also run on an integrated server) runs, by default, at 20 tps. 20 is the best tps your game can run at. The lower this value is, the more lag (not low fps) you will experience.
