R_OPENGL: OpenGL driver not accelerated!

Recommended Posts


What friends, I bring a small contribution that can be useful to several people. it turns out that I updated my computer to w10 from w7 and when I tried to open GZDoom 3.4.0 I got the error R_OPEN GL open gl driver not accelerated. to solve this you just have to apply the patch in the system32 folder or in the root of GZDoom.


link OpenGl 4.0 and 4.1: 





In my case I have:

Intel i3 M350 2.27 GHz with intel HD Graphics.

and Windows 10 Single language 64 bit.
