Can USB port optimization fix RT500 Digital lag in Atomic Heart?

Get this: I bought a fancy cooler with a screen, and it turned out to be the reason my game was stuttering. The PCCOOLER RT500 Digital screen syncs temps via USB, and it was clashing with the motherboard's I/O scheduling, causing frame times to bounce wildly between 12-30ms. I tried disabling the temp display in the software, but the lag stayed—turns out the USB polling rate was just too high, which is honestly ridiculous. I went into the BIOS and forced that specific USB port to 2.0 mode to lower the bandwidth overhead and switched the cooler to Performance mode. Monitoring via RTSS, the frame times finally tightened up to 8-13ms. I had some weird screen flickering after the port change, but updating to the latest chipset drivers cleared it up. CPU temps are now a steady 68-75℃. I exported the I/O conflict logs just to be sure, and everything looks clean now. Who knew a screen could be this annoying?
