I already posted a question before but I didn't really get any advice/help. I'll be a bit more brief/general in hope it'll help.
I have an
MSI HD 7850 with the
Catalyst 12.4 drivers installed. I've found that I'm having bad 3D performance for some reason but I'm not entirely sure what. I suspect it may just that the graphics card is new and AMD just need to work on their drivers but it would be nice to get advice and narrow the problem down so that I can be sure rather than wait for driver updates that may not even help.
I ran gxlgears to give some general idea of how bad the performance is. At default size it is averaging around 2000 FPS. The command
glxinfo confirms the renderer is using
AMD Radeon HD 7800 Series with
OpenGL version 4.2.
As asked for others:
These confirmed that everything was configured correctly.
Within Unity and Gnome Classic:
glxgears had an FPS of around 2000 FPS
fgl_glxgears had an FPS of around 544 FPS
glxgears had an FPS of around 4600 FPS
fgl_glxgears had an FPS of around 1600 FPS
In the end it was discovered that Compiz was causing a large performance decrease and solution was simply to change window manager for the time being. Thanks to TechZilla for all his help!
