(2025.10.09) GeeXLab 0.66.0

GeeXLab 0.66.0 is available for Windows 32/64-bit, Linux x86-64 (GLIBC 2.31) and Linux arm64 (GLIBC 2.41). The ARM64 version has been compiled on latest Raspberry Pi OS Trixie (Debian 13) that comes with GLIBC 2.41.

GeeXLab is an X11 app. It can run with Wayland (thanks to Xwayland, the X11 to Wayland translator) but you will quickly see crashes (especially when doing drag and drop, see this article). So to get the most out of GeeXLab on Trixie, it’s recommended to switch to X11.

Updated libraries

The following libraries have been updated to their latest versions:

Core libraries:

– Dear ImGui: version 1.92.3 (all platforms).
– SQLite engine update to version 3.50.4 (all platforms).

Plugins:

– GPU monitoring: new commercial names, new GPUs supported, better support of Intel Arc monitoring on Linux (tested with Intel Xe driver + Linux kernel 6.16) and support of Raspberry Pi 5 VideoCore 7 monitoring.
– FFmpeg: updated with latest FFmpeg 8.0 SDK on Windows 64-bit and Linux (x86_64 and arm64).
– NVIDIA PhysX: updated with PhysX 5.6.1 on Windows.
– Python 3: updated with latest Python 3.14.0 on Windows.

 
GeeXLab 0.66.0 is behind all the following applications: FurMark 2.10, GPU Shark 2.10, ASUS FurMark 2 ROG Edition 2.10, MSI Kombustor 4.1.34, GPU Caps Viewer 1.64.3 and YAFFplayer 0.12 and MadView3D 0.5.6.

(2025.10.23) UPDATE: GeeXLab 0.66.1

GeeXLab 0.66.1 is a maintenance release that fixes several bugs in the Vulkan renderer. On NVIDIA, some of these bugs prevented the launch of ray tracing demos. These ray tracing demos worked fine with few months ago with NV R576.xx drivers. NVIDIA has updated its Vulkan driver (in R580/R581) with a better implementation of the Vulkan API specs and indeed, thanks to the latest Vulkan SDK 1.4.328.1, I found and fixed Vulkan bugs in my code.

(2025.10.26) UPDATE: GeeXLab 0.66.2

GeeXLab 0.66.2 is a maintenance release that fixes a bug in the Vulkan renderer that affected Radeon RX 7000 / RX 6000 Series (and maybe the RX 5000 Series but I didn’t test). The bug was related to the configuration of a memory barrier. This bug was not present on RX 9070/9060 Series.

The new Dear ImGui 1.92 has a lot of changes and breaking changes. Usually I need 5 min to update ImGui, but this time, at least two hours have been necessary. According to my first tests, Dear ImGui support seems ok in GeeXLab 0.65. Same thing for the different extensions (implot, color text edit, imnodes, etc.), they all work.

2 – Release Notes

GeeXLab 0.60.0 is available for Windows 32/64-bit, Linux 64-bit (GLIBC 2.31) and ARM64 (GLIBC 2.36).

This new version of GeeXLab brings many small changes, bug fixes and improvements.

Updated libraries

The following libraries have been updated to their latest versions:

Core libraries:
– Lua engine: version 5.4.7 (all platforms)
– Dear ImGui: version 1.91.1 (all platforms)
– SQLite engine: version 3.46.1 (all platforms)
– curl: version 8.10.0 (windows)
– LuaSocket: version 3.1.0 (all platforms)

Plugin libraries:
– FFmpeg: version 7.0.2 (windows – other platforms: 7.0)
– ASSIMP: version 5.4.2 (all platforms)
– PhysX 5: version 5.4.0 (windows)
– Python 3: version 3.12.6 (windows)

 
GeeXLab 0.60.0 is behind all the following applications: FurMark 2.4, GPU Shark 2.4, ASUS FurMark 2 ROG Edition 2.4, YAFFplayer 0.10.0, h4shg3n 0.5.5, MSI Kombustor 4.1.30 and MadView3D 0.5.0! That’s why this release took me a bit time to finalize.

arm64 / aarch64 and Raspberry Pi platforms

A word about arm64 / aarch64 platform. Now GeeXLab is available in two flavors for arm64: one pure arm64 version and one arm64 version for Raspberry Pi. Both versions have been compiled on Raspberry Pi OS Bookworm on a RPi 5 hardware. The pure arm64 version should work on any Linux for arm64 with GLIBC 2.36 or higher. I don’t have a non-RPi arm64 platform, so if you, dear reader, have such a platform, please try to launch GeeXLab and let me know if it works. The second version is still for arm64 but specifically for Raspberry Pi hardware / OS: this version has dependencies with the RGBA Led Matrix support and GPIO support using WiringPi.

A second word about arm64 versions. GLIBC 2.36 is now required because GeeXLab is now compiled on the Raspberry Pi 5 board with Raspberry Pi OS Bookworm (Debian 12). It’s now a pleasure to work with the RPi 5, this board is fast and everything run smoothly (except Xwayland that still does not work). The latest iteration of Raspberry Pi OS Bookworm (July 4th 2024) seems to work on all Raspberry Pi hardware (RPi3, RPi4 and RPi5) that’s why Debian 12 Bookworm is now my new OS for RPi development.

NVIDIA Vulkan driver on Windows

Let’s quickly talk about the gh_renderer.bind_render_window() added to GeeXLab 0.60.1. This function is called in the startup demo of GeeXLab (in the startup-demo/ folder in init.lua). The call to bind_render_window() deserves an explanation.

Without this call, the startup demo crashes if there are two NVIDIA graphics cards in the system. In my development machine, I have a GeForce RTX 2070 + GeForce GT 1030 drove by R561.09. If I remove the GT 1030, the demo works fine. With both cards, the demo crashes. This is an OpenGL demo that in middle of the init script, initializes Vulkan and reads Vulkan information (see InitVkInfo()). Any OpenGL call after InitVkInfo() leads to a crash (OpenGL function pointers seem correct but crash when we called them). After few hours of debugging, I had the feeling that the crash happened as if the OpenGL context was lost or not properly restored after Vulkan calls. That’s why I tested with bind_render_window() and… YES, that fixed the crash! The bind_render_window() function is a wrapper around wglMakeCurrent.

However, it’s not a victory. The crash is still there in 32-bit. With bind_render_window() the crash disappears in 64-bit but not in 32-bit.

Duplicated Vulkan devices

The other thing is that with 2 graphics cards, the NVIDIA Vulkan driver duplicates all Vulkan physical devices. Instead of detecting
two physical devices (the RTX 2070 and the GT 1030), the NVIDIA Vulkan driver returns:
– GPU 0: NVIDIA GeForce RTX 2070
– GPU 1: NVIDIA GeForce RTX 2070
– GPU 2: NVIDIA GeForce GT 1030
– GPU 3: NVIDIA GeForce GT 1030

There is probably a bug in the NV VK driver. I tried to uninstall it (I used the latest DDU 18.0.8 for that), reinstalled it, but no change, any Vulkan utility (GPU Shark 2, GPU Caps Viewer, Vulkan Capability Viewer, vkinfo, GLview) still displayed 4 devices…

Modern graphics programming is blood, sweat and pain!

Here’s a short video about a 3D character animation project using Machine Learning done in Python 3 and rendered with GeeXLab. This is a project from the engineering school Haute Ecole Arc in Neuchatel, Switzerland.

In this project, we investigate statistical models to generate 3D running motions in realtime. In particular, Principal Component Analysis provides realistic results. The main limitation however is that the latent space dimensions are not meaningful to the end-user. Additional investigations are needed to create new statistical models that use explainable parameters.

2 – Release Notes

GeeXLab 0.59.0 is available for Windows 32/64-bit, Linux 64-bit (GLIBC 2.31) and Raspberry Pi OS 64-bit (GLIBC 2.31). This new version comes with improvements, bug fixes and updated support of Raspberry Pi!

The support of the Raspberry Pi platform is back but only in 64-bit (updated and compiled on Raspberry Pi 4, tested on Raspberry Pi 5). It takes a lot of time to maintain GeeXLab for all platforms so 32-bit versions of GeeXLab for Linux and Raspberry Pi will receive less updates.

GeeXLab 0.59.0 will power the following applications: FurMark 2.3, GPU Shark 2.3, ASUS FurMark 2 ROG Edition 2.3, YAFFplayer 0.9.0, h4shg3n 0.5.4 , MSI Kombustor 4.1.30. I will try to update MadView3D as well!

Updated libraries

In GeeXLab 0.59.0 the following libraries have been updated to their latest versions for all platforms (windows, linux and raspberry pi):

Core libraries:
– Dear ImGui: version 1.90.5
– SQLite engine: version 3.45.3
– curl: version 8.7.1
– WiringPi (Raspberry Pi only): version 3.2.0

Plugin libraries:
– FFmpeg: version 7.0.0
– ASSIMP: version 5.4.0
– FMOD: version 2.02
– OpenVR: version 2.5.1

GeeXLab on Raspberry Pi OS 64-bit (debian 12 bookworm, Raspberry Pi 5 board):
