Describe the Bug
I have been playing bloodborne for testing in both OS, same system (HW) and same build (v0.13.0), I have 100+ fps in most areas on windows, on linux I can get at 48fps most of the time, max 60fps.
The issue looks to be the way that geometry is handle, because inst patch/cheats related, already disable almost everything (just vsync off to get more fps) and the issue is the same, resolution patchs doesnt matter much, etc. The only thing that does is the complexly of the area that is been render, the dream, for example, is always 60fps+ on linux, but the first or 2nd lamp is always 40~48fps when looking to the city (but 60fps when looking to the sky).
At the same time, Windows performance gets microstutter a lot of the time, linux is stutter free.
Reproduction Steps
just playing the game on linux shows a performance degradation, comparing to windows 11
patchs that I normally use (same in both OS):
Enable DevKit: ON
Add DMEM: 9999mb
Skip intro: ON
Disable Chromatic aberration: ON
TaskSplit patch: ON
Disable HTTP Requests: ON
Uncap FPS: ON
Vblank: 120hz (now 60hz)
Resolution patch 2560x1440p
Like I said, when I disable all patchs the performance degradation is almost the same in linux, not more than 10fps difference when all patchs in the list applied,.

I'm experiencing largely the same thing with a similar setup, 5900x and 9070 XT. The performance increases if you drop to version 0.9.0, but it's never as good as Windows.
@0x6de commented on GitHub (Dec 31, 2025):
I can confirm i have the same issue on Arch Linux.
CPU: AMD Ryzen 7 5800X3D
GPU: AMD Radeon 9070XT
tested on: Arch Linux | Kernel: 6.18.2 | Desktop environment: KDE 6.5.4 (wayland)
On windows 10, the game runs 60fps almost perfectly, but on linux, there are multiple areas where the game drop to 35~40 fps. Tested this on the same areas, with or without cheat/patch, lower resolutions etc and the result is always the same, linux often drops to 40 fps where windows doesn't with similar settings and on the same exact location.

Same on cachyOS (arch based): I see a significant performance degradation when running bloodborne on chadps4 on linux vs windows 11.
@Mapachuelo commented on GitHub (Jan 16, 2026):
I had the same problem with Arch Linux; I thought it was a problem with its Intel Arc graphics card.
@jimmyvh commented on GitHub (Jan 16, 2026):
Also forgot to mention: It appears to be an issue from version
0.120.10 upwards@0x6de commented on GitHub (Jan 16, 2026):
Just tested different versions quickly, versions 0.12, 0.11 and 0.10 are all affected with this performance issue.
0.9 and downwards seems more stable on my end, maybe others can confirm this ?
@Mapachuelo commented on GitHub (Jan 16, 2026):
You are right that versions 0.12 to 0.10 have the same problem, but versions 0.9 to 0.7 do not have the problem and do not have as many stutters in areas where the problem occurs with the newer versions, although the performance is worse.
@CallieEZ commented on GitHub (Jan 18, 2026):
Yeah I'm getting awful performance on cachyos. Ryzen 9 3900x and an rx 7900xt, CPU is highly utilized on one core with gpu being underutilized, I can barely keep up 30fps 720p and it hovers around 22fps in 1440p. Can't get shadps4 working in wine just yet to see if this is platform specific
@0x6de commented on GitHub (Jan 18, 2026):
here's a quick video to demonstrate the performance issue, comparing 0.13.1 and 0.9 It seems that the issue was already there on 0.9 but to a lesser degree.

@ZahFireLight commented on GitHub (Jan 18, 2026):
Same thing on Cachyos on my part too, both on 720p and up to 1440p, the performance loss along with the fps on places like the great bridge is the same across resolutions mentioned. The fps and the general perf does in fact improve on shad v0.9
My system:
Cpu: ryzen 5 5600x
Ram: 32gb
Gpu: rx 6700xt
@nyomen commented on GitHub (Jan 29, 2026):
same happening here:
ryzen 7 5800x3d
4090
Bazzite
Major drops in fps no matter what resolution.
Since this is a bug since 0.10.0 it would be nice to be adressed. I mean it pretty much looks like that all linux systems having this issue, no matter how powerful the system itself is.
@nyomen commented on GitHub (Feb 19, 2026):
Can you add labels to this bug, like this ones, just to make sure it is seen.
And also better put this thread in this issue area:
https://github.com/shadps4-compatibility/shadps4-game-compatibility
instead of the just issue area of shadps4
https://github.com/shadps4-emu/shadPS4
Took me also a while to get the difference....
