Thanks. Let's add some cc's. Can you please describe your workload
and some estimate of the slowdown?
Patrik has also seen this and his description is
: I'm using an Asus Zenbook UX31E and have been installing all RCs in
: hope of improving the Wireless and Touchpad functionality.
: However, when trying 3.7 (rc1 and now rc2) I have major performance issues.
:
: Easiest way to reproduce is to launch and play a game like Nexuiz,
: where the computer will lag, stutter and freeze until the machine is
: unresponsive within a couple of minutes.
: But an easy workload like browsing will also cause lags when switching
: tabs or redrawing a web page after a tab switch.
: Basically 3.7 is unusable for this machine.
