I did a further test, again with the initial configuration (Nvidia proprietary driver). I started ET Racer on a slope and maximized the window. I then set the background of the gnome-terminal to transparent. The impact of the terminal maximized with top running in it equals the impact of the gnome

I concluded slightly wrong in my last post. If blurring can lower CPU usage it is likely that it doesn't take place on the CPU. I wouldn't know about Windows 7 - I know it has some blur, but only for very small areas as far as I remember. And blur isn't really my problem because I can live withou

Dimitri, I think unity's blurring method is probably inefficient. Certainly it seems so when compared to Windows 7 on the same hardware. However I won't criticise the Unity code too much while I have nothing better to offer. -- You received this bug notification because you are a member of Ubuntu

When I switch to the nouveau driver I have the same behaviour as you with Intel graphics. But do we know where transparency is calculated, do you know? Assuming it uses the CPU, then the reason why nouveau and intel drivers don't utilize the CPU is as you said a lower frame rate such that transpa

2012-06-10 Thread Daniel van Vugt
With intel graphics I find the opposite -- compiz CPU consumption is much lower when the blur is active. This is probably because it halves the frame rate that compiz can achieve :( If you're finding CPU is higher in this case then it's probably a lot to do with the NVIDIA driver, which is known t
