Fixing Fanxiang S790 stutters with 4K MODs in RDR2?
Running 4K MODs on a 4TB drive should be a breeze, but getting random hitches in Saint Denis made me want to roast the driver compatibility. The Fanxiang S790 was choking on the massive textures, with 4K random read I/O wait times jumping between 10ms and 80ms, killing my frame rate. I tried turning off Ambient Occlusion, which just made the game look ugly without fixing the lag—a total waste of my life. I eventually used a pro tool to recalibrate the 4K partition alignment and manually moved the virtual memory to the fastest area of the SSD. AIDA64 stress tests showed random reads stabilizing at 65-72MB/s, and the loading hitches hit zero. I actually tried flashing a third-party firmware first, which caused the drive to drop offline entirely—I had to use the factory tool to force a recovery. Temps are now 50-58℃ with a 75-85% controller load. 4K textures load perfectly now, and the input feels snappy.
