There's no reason an 850m should be horribly slow. That's probably getting CPU-locked, there, which isn't surprising because mobile CPU's are utter shit. This can happen even despite the GPU being fairly decent.

I'm betting the 960 is in a desktop rig that has a much bigger CPU that's able to handle all the effects thrown at it. That makes a huge difference with mods like Brutal Doom.

Ok then the only possible reason i can think of is that the CPU gets much more to do under certain conditions when using Open GL and not that the Graphics card does much more at all but the "sync" between them takes extra time, i absolutely does not know any of this but i cant think of another explanation in my case, and thanks for the replies you saved me buying a new GPU just to play doom better.

That's pretty much what it boils down to. And you're welcome.

For me OpenGL is much slower than Softpoly or Vulkan on any wad. AMD FX-6300, Geforce GTX 1050, linux. Waiting for Vulkan to stabilize, now it has major bugs.

Are you using proprietary NVIDIA drivers? Performance should be mostly equal to Windows on the same PC.
If you are using Nouveau, well, good luck then.

Did you report them? I don’t see any though. There are two opened issues at the moment.
However, they seem to be specific to particular settings and hardware configuration.
“Major bugs” term is not only an exaggeration, it’s just a deception.

Proprietary of course, nouveau doesn't have Vulkan.
I'll try to report Vulkan bug.
edit: tried to reproduce "major" Vulkan bug but it disappeared. If it will appear again i'll report it.

Sure it doesn’t. This was my reply on your post about bad performance with OpenGL.
