English forum / Re: GeexLab 0.13 Direct X 12 CRASH on startup
« on: February 28, 2017, 07:15:20 PM »
Ok I've done a test with my notebook ASUS GL553VD that has a GTX 1050 and a HD Graphics 630. And at first sight, DX12 demos work fine on the HD Graphics 630 (with graphics driver v4550):

According to your dxdiag report, you have the driver v4358. Maybe this old driver is the source of the crash. Try a more recent one:
- v4590
- v4501

Anounced today the Game Developers Conference, OpenXR is an open standard for portable Virtual Reality (VR) and Augmented Reality (AR) applications and devices.

The cross-platform VR standard eliminates industry fragmentation by enabling applications to be written once to run on any VR system, and to access VR devices integrated into those VR systems to be used by applications.

English forum / Re: Raspberry Pi 3 as a tiny VJ platform

or does geeXLab need windows and cannot display directly onto the framebuffer?

GeeXLab for RPi exists in two versions: one with OpenGL 2.1 and one with OpenGL ES 2.0. GeeXLab with OpenGL 2.1 requires X11. GeeXLab for OpenGL ES 2.0 does not use a window manager, it renders the scene  directly in the framebuffer. Maybe you can try this version, and start GeeXLab and load scenes via command line.

In the code sample pack, you will find OpenGL ES 2.0 demos in the gles-20/ folder.

Palit Microsystems Ltd, the leading graphics card manufacturer, releases a new line called KalmX and is consist of GeForce GTX 1050Ti series. With passive cooler and the advanced powerful Pascal architecture, Palit GeForce GTX 1050Ti KalmX - pursue the silent 0dB gaming environment.

Palit GeForce GTX 1050 Ti KalmX Features:

- The first passive cooler for GTX1050 Ti in the market
- Two nickel plated heat pipes
- Vast volume of nickel plated fins
- Copper base with heat pipes for best heat dissipation from GPU to fins
- No external power required, good for small case PC
- Affordable GTX series product, great C/P value
- Great Hardware Components

Ok, I think recent drivers from NVIDIA and AMD come with serious changes in Vulkan API that can explain the crashes. I prefer that. I have to dive in my Vulkan code (GeeXLab) and hunt the bug! I will do this asap.
