Dolphin, the GameCube and Wii emulator - Forums

The results are in, and they don't make much sense, given the comments of what was committed around the time things apparently got slow for me.

722 and less = Full Speed
732 and more = SLOW

Given 732 is "Expand the Android app's about menu to include additional info about a user's device." -- EDIT: Just realised there are of course *other* commits than the one mentioned on the build, I should know better!

I will note the building order/numbering does get a bit messy around there, so its possible my results are off due to that, I honestly don't know. The 722 I used was "OGL: remove version check for buffer_storage on windows".

683 = FAST
700 = FAST
722 = FAST
732 = SLOW
741 = SLOW

If you posted git revision hashes (about dialog!) instead of the dumb version numbers, there wouldn't be this ridiculous ambiguity that you noticed yourself.

I can't check over them now, but if you need me to, I will tomorrow

I know this is crazy, but I've seen 4xx and 5xx NVIDIA users having problems with Dolphin being much slower than it should be. Is it possible that BufferStorage isn't being detected properly on those video cards?

Disable the Vertex Streaming Hack in the last version that has it. If performance is absolutely identical, then the problem is probably something to do with BufferStorage not being detected or used.

Any idea what revision I'll need to look at? I assume the last one I get good speed in. Where do I find the "Vertex Streaming Hack" option because I can't see it anywhere.

Whatever was causing the slowdown is fixed in the very latest nightly build. The nightly build I tried a week or so ago suffered the same slowdown as all those others, so a recent change has solved the issues, so great

Yeah, thanks to your report they were able to narrow it down. Thanks.

Alright so what was it caused by and what commit fixed it? Did it affect the DX11 backend, OGL backend or both and/or certain hardware?

OGL backend for Geforce 400 and 500 series cards. Was about a 30% performance loss due to buffer storage not being utilized for some reason that escapes me.
