Based on the same code than the particle painter, here are some screenshots of a particle simulator. Around 200'000 particles + 8 attractors are processed by a compute shader (OpenGL 4.3).

Version 0.6.4.4 - 2014.06.04
! updated the OpenGL context creation under Windows and Linux for when
the required major version is 2.
+ added create_ex_v3() to gh_render_target lib.
+ added uniform_camera_matrices() and uniform_object_matrix() to gh_gpu_program lib.
MSI, world leading in motherboard technology, is pleased to announce its unleashing of the Z97 GAMING 9 AC motherboard to the public. The Z97 GAMING 9 AC from MSI is a custom designed motherboard, decorated with luscious new heat-sinks and unique Dragon Armor that highlight an arsenal of new features found on the board. It's masterpiece being Xtreme Audio DAC, a premium dedicated onboard sound card with specially selected high quality audio components, set up and tuned by professionals delivering 120dB Signal-to-Noise-Ratio (SNR) 192kHz / 32-Bit of purest sound quality for studio-grade Hi-Fi solutions and gaming headgear. The MSI Z97 GAMING 9 AC also comes with an Intel® Wi-Fi AC module with Bluetooth 4.0 and Intel® WiDi support.
The GTX 780 model has double memory: 6GB, while both have 10-phase power design that reduces power noise by 30% and increases efficiency by 15% versus reference designs. The cards are built with DIGI+ VRM and hard-wearing POSCAPs, while the DirectCU-like cooler has been upgraded with ’0dB technology’. When the GPU temp is below 65C the card will run in passive mode with the fans turned off. The large heatsink works to efficiently absorb and dissipate the minimal heat generated by low loads, so while you’re surfing the internet, watching videos, playing light games – your graphics card won’t make a sound.
Version 0.6.4.3 - 2014.05.28
* fixed a bug in gh_mesh.set_vertices_color() in Lua.
+ added set_vertices_color() to gh_mesh in Python.
+ added mouse_get_wheel_delta() to gh_input lib.
+ added new keyboard keys support (shift, ctrl, alt and windows key).
+ added keyboard_codes.lua in GLSL Hacker Lua libs folder.
+ added FreeImage plugin with floating point (96 and 128-bit) support.
+ added set_current_image_codec_name() to gh_texture module.

Vendor A has “the most capable GL devs in the industry and the best testing process.” It focuses on OpenGL implementations that work rather than on spec purity. It’s sexy. It’s fun. It’s also the vendor that’s pushing OpenGL as an alternative to Mantle or D3D12.
...this vendor (vendor A) will do things like internally replace entire shaders for key titles to make them perform better (sometimes much better). Most drivers probably do stuff like this occasionally, but this vendor will stop at nothing for performance.
Next up, Vendor B. Vendor B knows the OpenGL spec inside and out and focuses on implementing OpenGL correctly. Unfortunately, Vendor B is characterized as being “a complete hodgepodge, inconsistent performance, very buggy, inconsistent regression testing [and] dysfunctional driver threading…
And Vendor C? Vendor C has two major driver development teams, but doesn’t focus on graphics and is years behind Vendors A and B in implementing basic OpenGL features. It leads the way in open source graphics drivers, and has (mostly) public hardware specs. One driver is years behind but mostly stable as long as you don’t care about performance or features, while the other team’s driver is “a complete disaster…
