When it comes to playing Bloodborne on the shadPS4 emulator, the question of which version delivers the best performance and stability is one of the most frequently discussed topics in the community. Due to the game’s complex engine, heavy reliance on PS4-specific rendering behavior, and historically unstable frame pacing, Bloodborne remains one of the most demanding titles to emulate accurately. As a result, not all shadPS4 builds perform equally well.
Based on extensive community testing, user reports, and real-world benchmarks, the diegolix fork of shadPS4 is widely regarded as the best option for running Bloodborne, particularly if the game is your primary or only target. Specific builds, such as v0.5.1 WIP Full-BB and newer diegolix releases, consistently outperform mainline builds in terms of frame rate, stability, and visual correctness.
A frequently cited Reddit discussion highlights this conclusion, with users reporting significant performance gains and fewer game-breaking issues when switching to the diegolix fork:

Below is a detailed breakdown of why the diegolix fork is recommended, which builds perform best, what patches are essential, and how this compares to the mainline shadPS4 branch.
For Playing Bloodborne on shadPS4
For emulating Bloodborne on shadPS4, the diegolix fork—particularly builds such as v0.5.1 WIP Full-BB or newer—is generally considered the best choice for both performance and compatibility. These builds are specifically tuned for Bloodborne and related FromSoftware titles, incorporating targeted fixes and performance hacks that are not yet present in the main branch.
Many users report dramatic FPS improvements after switching to diegolix builds. With the correct configuration and patches applied, frame rates often reach 50–60 FPS, especially in indoor areas or less demanding zones. Even in heavier environments, performance typically remains far more stable than on the official mainline builds.
That said, testing mainline builds is still recommended if you want to compare results on your specific PC hardware. Emulator performance can vary significantly depending on CPU architecture, GPU drivers, and operating system. However, for most users focused on Bloodborne, the diegolix fork remains the clear first choice.
Key Forks and Builds
diegolix fork (MainBB / FullSouls)
This fork is highly recommended within the shadPS4 community for Bloodborne. It is often cited as the most stable and performant version available, with numerous Reddit users reporting smoother gameplay, fewer crashes, and substantially higher average FPS compared to the main branch. The fork includes game-specific hacks and workarounds designed to address long-standing emulation issues.
v0.5.1 WIP Full-BB
Among diegolix releases, v0.5.1 WIP Full-BB is frequently mentioned as one of the best-performing builds for Bloodborne. Many users consider it a “sweet spot” between stability and performance, especially on mid-range hardware. This build is often recommended as a starting point for new users who want reliable results without extensive troubleshooting.
Newer Builds (e.g., 0.9.0 and Latest Releases)
Newer diegolix builds continue to introduce performance improvements, bug fixes, and experimental features. While these versions may offer better results in some scenarios, they can also introduce regressions or new issues. For this reason, users are encouraged to test newer builds carefully and fall back to known stable versions if problems arise.
Essential Patches and Mods
Running the diegolix fork alone is not enough to achieve optimal performance. Applying the correct patches and mods is critical for smooth gameplay.
720p / 60 FPS Patch
This patch is essential. Bloodborne is originally capped at 30 FPS on console, and the 720p/60 FPS patch removes this limitation while reducing rendering load. Unlocking the frame rate is the single most impactful change for improving responsiveness and fluidity in emulation.
Skip Intro / No Motion Blur
Quality-of-life patches such as skipping the intro logos and disabling motion blur significantly improve the user experience. Motion blur in particular can exacerbate visual artifacts and performance drops under emulation.
Vertex Explosion Fix
This patch addresses a notorious graphical bug that causes severe mesh distortion, often referred to as “vertex explosion.” While the fix may disable facial customization, it is generally considered mandatory to prevent immersion-breaking visual glitches.
FPS Boost Mods (e.g., Bloodborne Enhanced)
Additional performance-focused mods can further improve frame pacing and stability. These mods adjust internal game parameters to better suit high frame rate rendering and emulator behavior.
Recommendation
The recommended approach is to start with the diegolix fork, install a well-regarded build such as v0.5.1 WIP Full-BB, and apply all essential patches and fixes. From there, test performance on your system and fine-tune settings as needed. While some users also suggest trying mainline nightly builds for comparison, the majority report superior results with the diegolix fork, particularly for Bloodborne.
Real-World Performance: Steam Deck Experience
One frequently cited user report comes from testing on a Steam Deck, which provides a useful real-world benchmark due to its limited hardware compared to desktop PCs.
The user reported struggling to maintain 25–30 FPS on the Steam Deck using the mainline shadPS4 branch, even with performance mods, the vertex explosion fix, and standard patches applied. After switching to the latest diegolix fork, performance immediately improved, jumping to 30–40 FPS, with 50–60 FPS achievable in select areas—using the same settings and mods.
The conclusion from this experience was clear: switching to the diegolix fork delivered instant and substantial gains with no additional configuration changes. While results may vary depending on hardware, this example highlights the fork’s effectiveness in real-world scenarios.
Built-In Hacks and Long-Standing Fixes
One of the key advantages of the diegolix fork is the inclusion of built-in hacks designed to address long-standing emulation issues specific to Bloodborne. These fixes target subtle but persistent problems that the main branch has not yet resolved.
Examples include:
- Flickering water issues, which are common in many mainline builds
- Audio loss after crashes or improper shutdowns, where the game launches without sound until restarted or reconfigured
While many of these issues may seem minor individually, together they significantly impact overall stability and immersion. The diegolix fork resolves or mitigates many of these problems, resulting in a noticeably smoother experience.
Relationship to the Main Branch
It is important to note that this is not a criticism of the main shadPS4 branch. The hacks implemented in the diegolix fork are widely understood to be temporary workarounds, not permanent solutions. They exist to bridge the gap until the main branch achieves more accurate emulation of Bloodborne’s behavior.
The long-term goal remains proper emulation without game-specific hacks. However, until that level of accuracy is reached, the diegolix fork provides a practical and effective solution for users who want to actually play the game rather than experiment with unstable builds.
If your primary goal is to play Bloodborne on shadPS4 with the best possible performance and stability, the answer is clear: the diegolix fork is currently the best version to use. Its targeted fixes, performance optimizations, and community-tested builds consistently deliver better results than the mainline branch, especially when paired with the correct patches and mods.
For users focused exclusively on Bloodborne, switching to the diegolix fork can dramatically improve frame rates, reduce visual glitches, and eliminate long-standing issues that hinder gameplay. While ongoing development in the main branch remains important, the diegolix fork stands out as the most practical and effective choice available today.
