Hi, everybody!

First of all I will tell you my environment:

GLFW version: 3.1.0
GLEW version: 1.11.0 [release 08-11-14]
Renderer: GeForce GTX 760
Driver: 344.65

I’m trying to implement a sample using OpenGL 4.5 to test the Direct State Access (DSA) extension. Unfortunately, the glfwCreateWindow returns NULL. Any idea?

Ahhh …
I have tested forcing glfwWindowHint but nothing happened.

Thank you,
Rodrigo Braga

This page lists the OpenGL version for the GTX 760 as 4.3, so you can’t make a 4.5
context.

Hi, Doug. I think that page you referenced is not up-to-date.
Because on this page is written that the GeForce 700 series (including GeForce GTX 760) supports the OpenGL 4.5 if the driver version 340.82 is installed (remember: I’m using 344.65 version).

What do you think?

Thank you,
Rodrigo Braga

Create a context without any window hints for version, which should work, then call glGetString( GL_VERSION ) and print the output. This will tell you what version is supported.

I have done this.
I will investigate a little bit more.
I’m sure it is not a problem with glfwCreateWindow.
Sorry for the false alarm and thank you ! :slight_smile:

Just for information, the problem was simple to solve:
The 344.65 driver version does not support the OpenGL 4.5. So I made a downgrade to the 340.82 driver version and it solved.

Excellent, glad to hear you’ve solved it.
