GtexCPUPlugin — CPU ground-texture backend

Plain C++17 (optional AVX2) implementation of the ground-texture RegCore backend, plus the managed plug-in that exposes it to DetourLite. No CUDA and no Intel SYCL runtime required, so it runs on any x64 machine — the right choice for bring-up, CI, and boxes without a usable GPU. It is slower than the GPU backends; use windows-regcore-sycl or OtherAlgorithms (CUDA) in production.

Install

Unzip next to DetourLite.exe:

DetourLite.exe
run-gtexcpu.bat
plugins/GtexCPUPlugin/GtexCPUPlugin.dll
plugins/GtexCPUPlugin/regcore_gtex_cpu.dll

Select the backend

RegCore discovers backend classes from loaded assemblies and takes the first entry in DETOUR_REGCORE that loads:

set DETOUR_REGCORE=gtex_cpu,cuda,sycl

run-gtexcpu.bat does that for you. If gtex_cpu fails to load, RegCore logs the failure and falls through to the next candidate, so a broken plug-in degrades instead of dead-ending.

Testing it

The DetourLite + GTex CPU (Windows) bundle ships this together with DetourLite, the classic WinForms UI and a ready ground-texture configuration, so you can unzip and run.
