Annoying delays

Oct 20, 2008 at 12:51 PM
It takes about 1.5 seconds to switch desktop on my notebook (AMD Turion X2 Ultra Dual-Core 2200 МГц (ZM-82), 2048 Mb DDR2-800MHz, ATI Mobility Radeon HD 3200).
Can the speed be improved?

PS I tried all settings in appearence tab. No fade or Real Fast are not fast enough.
