In OpenTK you should be able to get this data with the function OpenTK.Graphics.OpenGL.GL.GetString.Originally Posted by BeoWulf
Just call it somewhere after you initialized your gamewindow and output the results.

Looks like you've got a newer Intel chipset.GL_VERSION: 3.0.0 - Build 8.15.10.2353
Different hardware supports different version of OpenGL. Specifically: OpenGL 4.x has tessellation, random image write support and a number of other goodies. Intel GPU's do not have any of these capabilities, so regardless of how new the drivers are, that hardware does not have that ability, thus it cannot report GL 4.x. [As a side note, GeForce 8xxx, 9xxx, 1xx, 2xx and 3xx also cannot support GL 4.x, but their drivers are regularly updated by NVIDIA].I thought OpenGL will be updated automatically by Windows-Update, but i got no one?
My usual bet is that the Intel GPU and driver combination is what is causing your issues, but .... sometimes it pays to not jump the gun.
Check got GL errors (glGetError), if an error comes up, pinpoint what GL call(s) generate the error(s).
Also, check that your shaders successfully compiled and linked on the laptop.
hi,
first thanks for your answer.
I want to remember that i use OpenTK-GameWindow. In my Programm i dont get a error, dont know why, but when you install OpenTK, u will get the OpenTK-Sample Browser. In the Sample OpenGL->Picking, thats what i implemented and what cause my problem, i get always the Error "Error at Swapbuffers: InvalidEnum"
The source code of that Example is:
So the Error occure in the OnRenderFrame() when SwapBuffers() is called.Code :using System; using System.IO; using System.Drawing; using System.Diagnostics; using OpenTK; using OpenTK.Graphics; using OpenTK.Graphics.OpenGL; using OpenTK.Input; using Examples.Shapes; namespace Examples.Tutorial { /// <summary> /// This demo shows over which triangle the cursor is, it does so by assigning all 3 vertices of a triangle the same Ids. /// Each Id is a uint, split into 4 bytes and used as triangle color.

As u can see the Shader is commented and not used, so i dont use it, too. Because im a beginner in OpenGL-Programming. Could it be that thats the problem?
