Actually, we are in active contact to engineers from both AMD and Nvidia. If you like, you can tell them that recent driver releases (cf.
https://www.facebook.com/dolphin.emu/posts/563399847091791 ) have been crashing the OpenGL backend if format change emulation is enabled (i.e. the corresponding checkbox in the hacks section is unticked). We've already forwarded that information, but I guess it doesn't hurt telling them twice so they don't forget about it

I am running a beta build past driver 334 with Dolphin 4.0.2 that is running very stable in OpenGL. Perhaps it was fixed.
But as I can see reading this new article in future builds D3D is going to be the renderer to use now, even for nVidia users who want accurate and better performance.
Chances are Dolphin 4.0.2 isn't affected, you should probably retry with the nightly builds.

Yes, I plan on playing with the latest nightly build tonight.
Well as expected the latest builds definitely wreck havoc on performance due to the changes. OGL prior to the changes use to be the best mode to use for me, but now with the new builds D3D has to be used and it doesn't perform that great.
I guess there was no way to have some fall back hack setting for nVidia users in newer builds so at least they could get the other fixes but still use the old way of processing? I guess I will be stuck with 4.0-1146-x64 of Dolphin so I can keep the performance of OGL until the performance issues with nVidia if/can be resolved.

Yes, you're right that there is no such way that anyone would be willing to spend hours or days of time on. That said, it's something nvidia has to fix in their drivers (and hopefully will soon enough).
Long time lurker and admirer of the Dolphin teams' work. Congratulation. I enjoyed that article a lot. I don't know the exact specifics of technical issues, but I got the overall jist and I think it's amazing work. Thank you!
Seems like the whole integer calculation process would be more efficient than using floats in the first place.
Great work! I feel this warrants another official build!
I'm looking forward to upcoming DX12 and possible support within it in Dolphin.

Likewise assuming it can be utilized in order to improve performance. There is less overhead so that's promising. Anyway, going to try out the new build and see how it goes. I have an overclocked GTX 780 so hopefully I won't notice the Nvidia performance degradation all that much (granted I have always enjoyed using 4x internal res so I may have to tone that down at the very least). I'll switch to the D3D back-end if I have to.\
Thanks to everyone that made this leap forward possible. Looking forward to any future advancements.
