Can locking Gen 3 mode fix Great Wall GW3300 stutters?

Man, the loading speeds in this game are insane, but then it randomly turns into a slideshow, which is just ridiculous. The Great Wall GW3300 2TB's PCIe link was struggling with the massive planetary data streams, causing it to flip-flop between Gen 4 and Gen 3, creating 40ms - 60ms of instant latency. I tried limiting the max read/write speeds in software first, but while the spikes lessened, the load times doubled—it was absolute mental torture. I eventually went into the BIOS and forced the M.2 slot to Gen 3 mode and updated the chipset drivers to optimize the IRQ distribution. Checking with GPU-Z, the link state finally locked at 8GT/s, and that erratic hitching completely vanished. I did notice that locking Gen 3 dropped my peak read speed by about 1GB/s, but after a fresh format, it felt much smoother. The drive stayed around 52℃ - 58℃ with the heatsink working fine. Exported all link error logs to confirm the fix, and the interface is finally stable.
