I would disagree here. For display photographic images, almost no work is being done by the graphics card. Any basic card running as a frame buffer (with say 8MB) wouldn't perform much different from the 512MB card that seems to be standard. It is really only in 3D games or 3D display managers like Compiz where they will have appreciable benefit. With the right program your card could easily display 25 photos per second with no flicker - this is what any movie player needs to do!<br>
<br>Both Picasa and F-spot while feature rich, are probably rely too much on the CPU to do their work. Picasa is basically a Windows program running in emulation (using WINE), and F-spot is written using mono, which is a clone of the .Net framework. Probably the slickest way to view photos (and do basic manipulation) is gthumb. It used to be the default photo program until Hardy (you may need to install it from synaptic if you did a fresh install of Hardy).<br>
<br>I just did a 3-way test of the above 3 programs doing full-screen "paging" through some photos and gthumb is far quicker (at least 3-4 times) than the other two for this function. (I am viewing 2592x1944 images on a 1400x1050 so it has to do non-integer scaling/dithering to display these - which is where I think your problem was occuring.)<br>

</div>Okay. The DVI port works. Indeed, it all looks more crisp now. I<br>
tried an album in both Picasa & F-Spot. Photo's come up clear - I<br>
think, on first blush they're okay in both applications.<br>
<br>
The problem is/was confined to when I start I slideshow, as both<br>
applications make available.<br>
<br>
In the case of Picasa as soon as slideshow gets going the edges of<br>
images blur. "Dither" I think is the correct word.<br>
<br>
In the case of Ubuntu's F-Spot the slideshow is very slow. It takes a<br>
while to form the image. Once done it is fine.<br>
<br>
It seems to me that in both cases the program has to think too hard what<br>
to do??<br>
<br>
Any thoughts please.<br>
