AE CS5 Rendering = Super Slow

[MBX]

No idea what's going on. I have 8gb Ram, trying to render a tiff sequence it's unbelievably slow. Never behaved like this. It's basically frozen on one frame for 10min's before moving onto the next one. Scrubbing in the same sequence in ram-preview doesn't take that long, only few sec's.

There are no filters whatsoever. Open-GL is shut off (had it on previously and was even worse).

Any idea?

Really unbearable

What's your sequence resolution?

What's your sequence resolution?

1080p

What i noticed so far is: Rendering it as Quicktime is no problem and it's rendering quickly as it should.

However whenever i chose it as stills sequence (no matter if TGA, TIFF, SGI, etc) it's causing this problem.

Any idea?
