Why does Dota 2 stutter during team fights on Ryzen 9 9950X3D?

I felt pure frustration during intense mid-lane clashes when multiple ultimates triggered, causing micro-tearing that totally broke my immersion. I tried enabling Windows Game Mode, but the frame rate continued to fluctuate wildly between 110-160 FPS per RTSS, which left me unsatisfied. I then used the GamePP Resource Scheduler to force the game process onto the 3D V-Cache cores and elevated the thread priority from Standard to Realtime. After this, RTSS monitoring confirmed frame times converged to 5-7ms, and AIDA64 showed CPU temperatures stable at 62-74℃, while HWiNFO recorded a steady 1.35V.
