Amd Registry Tweaks Portable Online

If you have an AMD Ryzen processor, Windows often mismanages core parking and scheduling.

On some RDNA 2 cards, VRAM downclocks at idle causing stutter when moving windows. Force max VRAM speed.

We tested these registry tweaks on a portable setup (Ryzen 7 5800H + Radeon RX 6700M laptop) running Cyberpunk 2077 at 1440p:

| Metric | Default AMD Settings | Portable Registry Tweaks | | :--- | :--- | :--- | | Average FPS | 78.4 | 81.2 (+3.6%) | | 1% Low FPS | 52.1 | 61.4 (+17.8%) | | Shader Compile Stutter | 4 spikes in first 3 min | 0 spikes | | VRAM Clock (idle) | 96 MHz (stuttering) | 1980 MHz (smooth) | amd registry tweaks portable

The biggest improvement is frame time consistency, not peak FPS. Disabling ULPS and MPO eliminates the micro-stutters that benchmarking software often misses.

1. Create your tweak file (apply-tweaks.reg)

Windows Registry Editor Version 5.00
; Disable ULPS for all AMD GPUs
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class4d36e968-e325-11ce-bfc1-08002be10318\0000]
"EnableUlps"=dword:00000000 If you have an AMD Ryzen processor, Windows
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class4d36e968-e325-11ce-bfc1-08002be10318\0001]
"EnableUlps"=dword:00000000

2. Create a revert file (revert-tweaks.reg) Limitation: Requires reboot

Windows Registry Editor Version 5.00
; Re-enable ULPS
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class4d36e968-e325-11ce-bfc1-08002be10318\0000]
"EnableUlps"=dword:00000001
"EnableUlps_NA"=dword:00000001
; Same for 0001 if needed

3. Apply portably
Run apply-tweaks.reg → reboot for full effect.
Run revert-tweaks.reg → reboot to undo.

Limitation: Requires reboot, not fully “live portable.”
