In gzdoom, there's no option to turn on OpenGL-accelerated graphics. I've tried vid_rendermode 1 in the console.
Also older versions don't work for some reason(Says "GZDoom has stopped working")

Re: GZDoom not activating OpenGL
It's 'vid_rendermode 4' , not 1.
The option is located in the Video Mode menu.

Re: GZDoom not activating OpenGL
vid_rendermode 4 just sets it to "hardware accelarated".
