Fixing AMD Ryzen 7 7800X3D cache issues in Delta Force

When you're pushing a fast assault, a 0.2-second hitch completely ruins the muscle memory, and that instability made me really uneasy. The 3D V-Cache should be carrying the load, but with default drivers, the core clocks were bouncing between 4.2GHz - 4.7GHz, causing the cache hit rate to tank. I tried enabling PBO in the BIOS, but while I gained 5 average FPS, the stuttering actually got worse, so that was a dead end. I eventually updated to the latest AMD chipset drivers and disabled Core Isolation in Windows. HWMonitor showed the clocks stabilizing above 4.5GHz, and frame times settled at 7ms - 11ms. I had two slow boots right after the driver update, but a second restart cleared it. CPU temps are now 62℃ - 68℃ with fans at 1,500 RPM. Cache hit rates are back up, and memory temps are stable at 58℃ - 63℃.
