OpenGL slower than D3D on Nvidia GTX 750 Ti - Kirono - 11-18-2015
As the title says, OpenGL is PAINFULLY (~10 FPS) slow while Direct 3D is nearly perfect speed (~30/60 FPS[depending on game]).
According to the main blog post announcing 4.0 , OpenGL is supposed to be the faster of the two on Nvidia cards.
If so, Why am i getting the opposite?
Setup Specs:
AMD Phenom II 1100T x6 3.30 GHz

Nvidia GeForce GTX 750 Ti
Games loaded from Hybrid HDD.
Program loaded from 7200 RPM HDD
Windows 10 Pro x64
Dolphin 4.0-8165 x64

Is there a build where it's not slow? Or are both the dev releases and the stable release slow on OpenGL?
Also, which games did you try/

Also, do you have vsync turned on in OpenGL settings? If so, try turning it off.

I tried several GC and Wii games. I have Vsync disabled. When using 4.0.2, OpenGL is nearly as good as D3D in 4.0-8167.

Okay, so if you have a working build and a not working build, can you please bisect the issue? We can't reproduce this.
Use this utility to make it easy.

Don't worry, you won't have to test thousands of builds.

D3D is also faster for me on both my 970 and 970m.

Probably not this big of a difference though.

What's strange is that I have a NVidia GeForce 750 GTX and I have the experience you'd expect. OpenGL runs great. D3D causes a lot of slowdowns and lag. I wonder why your experience is so different

Bisect will not launch. I double-click, but it just sits there with the busy cursor.

I'll look into it this afternoon. I released that tool just yesterday. Somebody else is reporting the same issue.
