It interesting the variation of render times on the same default preset [ Heinous Filter - no other programs running ] - the new one varies from 22.39 to 25.04 seconds on opening and closing FF and I've noticed this on other filters - is it because the machine is doing other things behind the scenes or is it just my machine is lazy and will do it in it own good time - does this happen to anyone else smile:|

I'm sure you know of this already but if not you might find it interesting. If you open up the taskmanager (ctrl+alt+del) you can click the "processes" tab. This will give you a list of all the programs you have running under the surface. People that are active online and don't clean up often will often have loads and loads of extra programs in there. It's worth a look to see if anything is using CPU usage at random intervals, it would probably be the culprit for the strange Filter times.

Thanks KG just having a look as I type, under services there are so many things I have no idea what they are or are doing - under processes there is not much going on System Idle seem the only thing active using 1 to 4% of cpu, dwn.exe is randomly using [ do you know what that is ] - my computer knowledge is small, just like the pretty colours LOL - interesting, thanks for reply smile:)

Hi Carl

I think your referring to the Desktop Windows Manager (dwn.exe)

This is the controller for Vista's Aero interface, so I'm not surprised that its constantly active and taking up CPU cycles and RAM

As well as hammering the hell out of your graphics adapter...

I would also like to note that modern CPUs (even desktop ones) come with a power-saving feature that throttles CPU performance when it's not active. The throttling usually comes up and down with a slight delay leading to large time variations.
Also, if filter contains a number of bitmap-based components or is rendered with a large resolution the disk perfomance might be in question, and disk performance varies a lot more than CPU since even a short background operation of some OS service using disk might add a couple of seconds to rendering time.

Your right it does seem the variants is greater with the filter I've tested with larger number of bit map components - I have now thrown out my assumption that render times are static smile;) smile:)
