Multiple screenshots in quick succession

I used to use FRAPS for screenshots & it would take them as fast as I could hammer the capture key. Now it's not working with 10, I have found the Windows+PrtScn feature which is great, however it can only take 1 shot every 0.5 secs.

Are there any screenshot programs that do work with 10 and could improve on this? It needs to screenshot local video and in-browser.

Thanks.

Why don't you use a screen recording program like e.g. WMCapture. Then you can process the individual frames.

WM Capture | WMRecorder

I do use Open Broadcast Software for game recording and that has a "monitor capture" recording option, so yes I suppose I could record then extract frames but does seem like a very long way round it.
