Ubuntu – Bad 3d performance of intel ironlake

intel graphicsperformance

I'm using ubuntu 13.04 and got VERY bad 3d performance with intel ironlake comparing with a windows installation.

Is there any way I can improve this?

I already tried various paramaters of the i915 kernel module, but that didn't help much…
SNA is already enabled.

Best Answer

Add the following option in grub file

i915.semaphores=1

Then

 sudo update-grub

Mine is

 GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.lvds_downclock=1 drm.vblankoffdelay=1  i915.semaphores=1"

Try adding this to /etc/environment

 CLUTTER_PAINT=disable-clipped-redraws:disable-culling

The first thing you need to check is GLX Direct Rendering, You can use the generic mesa-utils, or fglrxinfo which is provided by FGLRX. You already have fglrxinfo installed, so you should try that first.

Run this command in a terminal.

fglrxinfo

Report back what the output shows, which will tell us if the fglrx is configured correctly.

next get glxinfo, which is installed via

sudo apt-get install  mesa-utils

Run this command to get your direct rendering status, it will be a yes or no answer.

glxinfo  | grep rendering

Use xvinfo to check for Video Overlay. Make sure x11-utils package is installed.

sudo apt-get install x11-utils

Run this command to check for Video Overlay, should be a long listing, not an error.

xvinfo

This is just the basics, it doesn't verify the new HD video extensions. It should however, tell you if acceleration is even working.

Update:

Your settings are correct, and composting has been identified as bringing down your performance. Composting often brings down performance, especially when playing games in WINE.
