Bloodborne shadPS4: Controls Unresponsive, Character Won't Move or Attack

The cause is almost always the VBlank Divider setting in shadPS4. This is a single setting that must be set to 1 for Bloodborne. Any other value makes the game's internal timing collapse — the character still moves, but every input is buffered against a broken clock.

Fix:

1. Close Bloodborne if it's running
2. In shadPS4, go to Settings → Graphics
3. Find VBlank Divider — set it to 1
4. Save and relaunch Bloodborne

If VBlank Divider was already at 1, see the solutions below. But in over 90% of reports of this issue, VBlank was the culprit — it defaults to 1 but can be changed accidentally.

Why this happens: VBlank Divider controls how many times per frame shadPS4 signals the "vertical blank" interrupt to the emulated PS4 hardware. Bloodborne's physics and input polling are tightly coupled to this interrupt. Values above 1 divide the frequency, making the game think time is passing differently than it is — inputs appear to arrive on time but the game acts on them with the wrong timing.

If controls are unresponsive but VBlank Divider is already at 1:

Check the input device is mapped:

1. Settings → Input → confirm your controller appears under the mapped input device
2. If using a DualSense or DualShock 4: connect via USB (not Bluetooth) and ensure no other app is claiming the controller (Steam overlay with PS4 controller support enabled will intercept inputs)
3. If using an Xbox controller: ensure XInput mode is active — shadPS4 reads Xbox controllers natively

Steam is intercepting your controller: If Steam is running, it may be consuming PS4/DualShock input before shadPS4 sees it. Open Steam → Big Picture Settings → Controller → disable "PlayStation Controller Support" while emulating. Alternatively, launch shadPS4 outside of Steam.

Keyboard input not working: By default, shadPS4 maps keyboard keys to PS4 button positions. Check Settings → Input → Keyboard Mapping to confirm the layout matches your expectations.

If the game is running in what looks like slow motion (everything moves, but at half speed), this is a frame rate issue, not an input issue:

• Bloodborne runs at 30fps on PS4. If your GPU can't maintain real-time emulation, the game will appear to run at 15fps or slower — inputs work but the game world is slow.
• Check your GPU load in Task Manager while the game is running. If GPU usage is near 100% but FPS is below 30, you need a faster GPU (recommended: RTX 3060 or better for Bloodborne at 1080p).
• Reduce internal resolution to 720p in Settings → Graphics to reduce GPU load.
• VBlank Divider at non-1 values can also cause apparent slow motion — if you haven't checked it, do that first.
