# Horizon OC Toolbox
|
|
|
|
A borealis (full-screen, controller-driven) front-end for the Horizon-OC
|
|
benchmark / stress engine.
|
|
|
|
## Features
|
|
|
|
- **System Info** — live CPU / GPU / MEM (EMC) clocks, memory mode, thread count.
|
|
- **Benchmarks** — GPU bandwidth (copy/read/write), CPU bandwidth (3 threads),
|
|
and memory latency (L2 / full RAM), run on a worker thread with a live
|
|
progress readout.
|
|
- **GPU Stress** — a combined compute + memory GPU stress kernel with live
|
|
GFLOPS / dispatch / mismatch counters (start / stop). Any mismatch means the
|
|
GPU produced an incorrect result → the overclock is unstable.
|
|
|
|
The UI is built programmatically with borealis (no XML), so the app is
|
|
self-contained.
|
|
|
|
## Building
|
|
|
|
Requires devkitPro with the Switch toolchain. Verified building against
|
|
devkitA64 GCC 15.2 + current libnx.
|
|
|
|
borealis is vendored under `lib/borealis` (no submodule to init), and the
|
|
runtime resources it loads from `romfs:/` are committed under `resources/`, so
|
|
the build is turnkey:
|
|
|
|
```sh
|
|
make
|
|
```
|
|
|
|
Produces `Horizon-OC-Toolbox.nro`.
|
|
|
|
If you don't already have borealis' dependencies installed:
|
|
|
|
```sh
|
|
sudo dkp-pacman -S switch-glfw switch-mesa switch-glm \
|
|
switch-libdrm_nouveau switch-glad
|
|
```
|
|
|
|
## Notes
|
|
|
|
- Both borealis (deko3d) and the GPU-bandwidth test (EGL/GLES) are linked; the
|
|
bandwidth test creates and fully releases its own EGL context around the run.
|
|
- The Makefile force-includes `<optional>` for borealis' `dk_renderer.hpp`.
