Emulator

Also notice that Vertex Rounding problems are somewhat related to real XFB problems: in every revision where Vertex Rounding is broken, real XFB is broken as well (Vulkan backend)

I am wondering if this is related to the realxfb issue (bug in NV's SPIR-V frontend, which bypassing with the GLSL extension just happened to "work around"). Vertex rounding seems to work fine with the attached fifologs on my system.

For sure it is related

I literally have a GTX 760 and can't reproduce this... it's so frustrating. If someone on the team could reproduce this I'm sure we could figure out how to fix it.

I have a GTX 1060, dolphin-5495, linux 4.9.48, nvidia 375.82 (manjaro).

If I select Vertrex Rounding on Vulkan the video output is NULL

Also, this is how it looks on emulator

Hi Hyperniy, with your permission i´m going to refer your video to my issue #10527 because the FXAA problem in the 1:36

Did someone report to Nvidia about the broken Driver?

Either someone did and NVidia ignored them or no one has reported that yet because this issue has been known for a couple of weeks.

Tested on my GTX 1080 as well as the 780 now, and I still can't reproduce it. Tried combinations of vertex rounding/xfb/postprocessing, and all were fine. This was on Ubuntu 16.10 with nvidia-375, but I doubt distributions will change anything.

Not saying there isn't an issue, but I'm guessing it's somewhere in the driver or shader compiler. The latest NV dev driver has the GLSL extension "fixed" again, so we can re-enable it after that reaches the stable channel, and everything should be back to normal. Can't do much else for now.

Well that's a great new, so let's wait for the fixed driver

Nvidia released the latest driver (385.69) yesterday. Maybe is time to revert the changes of 5.0-5419 and test it with the new driver and see if fixes this issue and #10527

Tried with 385.69 and no change. Can't say I'm surprised, given it's not a major release. Hopefully the next major release will include the Vulkan changes/fixes present in the dev driver.

Yes, PR6111 fixes the problem

a bit off topic, but I think that the new Nvidia Driver (387.92) also gives Dolphin a 5% performance boost (at least on my system and with my games)

Yes, this PR fixes the problem

Now what? Are we waiting another Nvidia Driver release?

I think this issue and all the related ones can now be closed...
