Hello,
Could someone test the option
Quote:ogl_vertex_storage = 1
with latest GSdx on Mesa driver?
This option replaces some old codes (GL2) with the newer (GL4.4) GL_ARB_buffer_storage extension. Normally it is supported on Mesa since 10.2.
It brings quite a speed up on Nvidia. I'm curious with the free driver.
For mesa, are you referring specifically for AMD open source driver?
Any vendor will be fine. Code is mostly conmon anyway.
For some reason I'm getting errors when attempting to compile latest version on my own to test. I've switched to Ubuntu 15.04 beta. Perhaps I miss a dependency somewhere but it is late. I will test later. Looking forward to seeing results of speed increases.
Ok.Don t hesitate to post the error message.
I am unsure for the mesa driver but I can confirm a small speedup with the official nvidia drivers....
Yes I know. However I have some corruption, I need to add some protections...
I keep getting a strange assertion failure when enabling the option.
Code:

The strange part is the path here.
/home/vvvv/Build/pcsx2/common/src/Utilities/Linux/LnxHostSys.cpp(64) : assertion failed:
That would be a path on the VM that I compiled PCSX2 and doesn't exist on the machine I'm trying to run it on. When I set the option back to zero the game will start fine.
Normal, debug paths are put in the binary. So it get the one from the build machine.
Disable simd and use a dev build because the trace is empty.

Here's what I get now with the dev build.
