I used to use DS 3.0 on a fujitsu siemens lifebook p1610 2 months ago and being able to make a picture wih size up to 10000pixels with 198MB vido memory and 1Gb of ram.

Now with DS 3.1 and Dell Inspiron 1564 with 1gb of video memory and 3gbs of ram i can't do nothing larger than 8000pixels. The windows 7 states that the program has stopped wotking, and is checking for solution. Any thoughts?

Also when I open the DS 3.1 it says

Your graphics card, "ATI Mobility Radeon HD 5450 Series", or graphics driver is not supported and your hardware acceleration preference is enabled. If you experience graphics artifacts and/or any instability, disable hardware acceleration using the Graphics preferences page until a supported configuration is available.

Is this what makes the problem? Does it decrease the productivity of the hardware, I mean does the program runs slower than it is expected to?
