Bug ID: 105256
Summary: Slow performance using glDrawElementsBaseVertex
Product: Mesa
Version: 17.3
Hardware: Other
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/r600
Assignee: dri-devel@lists.freedesktop.org
Reporter: logan@bacoosta.com
QA Contact: dri-devel@lists.freedesktop.org
Original application bug report here:
https://github.com/gonetz/GLideN64/issues/1561
This bug happens using mupen64plus (N64 emulator) and the GLideN64 graphics
plugin.
The application uses VBO streaming
(https://www.khronos.org/opengl/wiki/Buffer_Object_Streaming) using
ARB_buffer_storage to upload the VBO data.
Multiple users that when using Mesa + r600 driver, the performance was abysmal.
It turns out that converting the glDrawElementsBaseVertex calls to glDrawArrays
fixed the problem.
You can see the commit that fixed the problem here:
