High CPU load during long delays between short exposures

[tlveik]

I'm gearing up for the eclipse and noticed that I see high CPU load during long delays between short exposures.  During those shots of the partial eclipse leading up to totality and then again away from totality.

I also see some flickering of certain elements on the screen during this time.  Then I noticed that if I minimize the program, the CPU load drops to normal.  I'm guessing that the program must be redrawing the screen repeatedly during those delays.

I'm always looking at ways to maximize battery life and these partial eclipse shots are going to take 3 hours.  Minimizing the screen is a decent work-around but it would be nice if I could keep the screen up.

Are you save to card or PC? 

[tlveik]

I'm saving to PC since I want to see the images.  Exposure time is about 1/200 and delay between pictures is about 2 minutes.  Plenty of time to finish processing the image so it shouldn't be that.

There you go, loading images does take some cpu.  No way around this.

[tlveik]

Not two minutes though.

[admin]

No, not 2 minutes.  You are getting high CPU for 2 minutes?

I'm suspecting your anti-virus... seen this before where the anti-virus would scan new images as they are downloaded.  Not saying this is the cause but try deactivation it and run a test.  At least disable the active scan if you can.

Keep us posted,

[tlveik]

Yes, 2 minutes.  Or more, as long as I set the delay.

First I should say that it is not maxing out CPU.  But CPU increases by 20%, which is quite a bit for a simple timer function.

This only occurs during the delay between pictures and not during the delay for a long exposure.

I tried disabling anti-virus as you suggested and didn't see any improvement from that.

Go to advance settings and select the blink setting for the progress wheel, this may help.

Tried the blink setting, it changed the appearance of the progress wheel as expected.  But didn't help CPU usage.

For what it's worth, the image thumbnails flicker one at a time during this delay.  It looks to me like the extra CPU use is going toward constantly redrawing the images on screen. I tried turning the thumbnails off, but that didn't help either.

Okay, I'll take a look but I'm not sure if I'll find anything.
