OK, here is a question I’m trying to figure out… Its hard to explain so ill have to be detailed..

So I have a 30′ inch cinema display and I do very detailed technical drawings in Photoshop CS2 at 600dpi with 50-100+ layers. Since im constantly resizing the image size on screen, zooming in and out – it always takes about 5-10 seconds for the screen to fully refresh and show the entire image. Of course on small sized images it takes no time to refresh but on these large PSD images of 200 plus megabites I’m tired of having to wait. Furthermore, after the screen has initially displayed the entire image zooming out and then back into that size it dosnt take so long again. But after i make a change to the image (draw a line) it has to wait 5-10 seconds again to refresh.

I thought maybe more ram would help but im at 4GB and it did nothing to speed up the refresh. I’m guessing this is graphics card related maybe? I am thinking i need a graphics card that is – what? – Faster -more memory? I don’t know. I’m hoping someone here can tell me if the graphics card is what i need to upgrade. I’m currently using a NIVIDIA Quadro FX 560. Can anyone suggest a graphics card that can handle what im doing and not make me have to wait?

Thanks,
Tyson

What are your system specs? Any card capable of running that monitor should be fine.

I suspect something else is at play.

Hi Tyson,

I could be completely wrong on this and I never work with images of so many layers as you describe, nor quite that file size, but I’m inclined to think the problem is other than with your graphics card. Why? Because you’re still talking about a 2D image and only rendering, at most, 4MPx of data (2560×1600) to the screen. 32-bit color would require a 16MB graphics card (I’m pretty sure this is the correct calculation) and yours has more than enough headroom at 128MB. Unless there is any kind of compatibility issue between the card and monitor, which I assume to not be the case, then I’d wonder if this is a driver issue or something else.

Of course, if you bought a graphics card locally, you could always explore whether that provides a solution and return it if not. Ditto for mail/online ordering but you’d eat the shipping costs.

What are your system specs and which O/S are you running?

Regards,

Daryl
