On some RDNA 2 cards, VRAM downclocks at idle causing stutter when moving windows. Force max VRAM speed.
Values from 0.0 to 1.0 (1.0 = 100%). 0.75 is the "sweet spot."

The /s flag runs it silently. No installation, no trace. On some RDNA 2 cards, VRAM downclocks at
Several community tools embody the "portable AMD tweak" philosophy:
These tweaks modify how the CPU and GPU handle instruction processing. If you apply a tweak and the screen
