I was playing with next version of CAESAR 4.40, lot of new and useful features. Graphics have lot of new buttons, will take some time to learn to use all of them.

Don't know what are the min. specs for PC to use the 4.40. I tried on my PC which has AMD 366 processor and graphics didn't behave right. Like, 'Zoom to Window' button when I clicked, the screen went blank and nothing happened.

But when I tried at work PC which has Pentium III 800, everything seem to work fine.

Output also has lot of new features.

I'm not that familiar with AMD processors, but if yours is really running at 366 Mhz, your use of CAESAR II must be painfully slow.

I wouldn't want to run CAESAR II on anything less than a 500 Mhz machine with 128 Mbytes of RAM. If you're planning on a new purchase, $2000 can get you a 1 Ghz machine with 128 Mbytes of RAM.

The bottom line is, "the software will perform better, the better your hardware is".

Now, as to the graphics question, here is a short list of things to do when a "Hoops Graphics Issue" is encountered:

• Try changing the "color depth" from "Control Panel\Display\Settings".
• Try switching from the OPENGL drivers to the MSW drivers, using the switch in the "Configure-Setup\Plot colors" dialog.
• Try turning off "hardware acceleration"
• Ensure you have the latest drivers for the graphics board in use.

If these steps fail, here is additional information from the graphics library (Hoops) vendor:
===========================================================
The problem here is that 3D acceleration on many graphics cards is buggy,
especially when dealing with low-end hardware. In almost all cases the
problems are not related but HOOPS but rather the OpenGL implementation on
the card. Most CAD applications provide a list of recommended gfx cards and
then err on the side of performance rather than stability i.e. they turn on
full hardware acceleration. If you are running into a lot of problems you
could set it so that HOOPS uses non-accelerated OpenGL which will mean that
you will get a lot more dependable drivers however you will get no hardware
acceleration. Then in an application options dialog you could provide a
switch where a user can turn on hardware acceleration.

As an example SolidWorks has two versions of their eDrawings product. The
free version which could be considered a mass consumer product (at least in
the CAD world) turns off hardware acceleration by default while the
Professional version turns on hardware acceleration.
=======================================================

Finally, go to the SolidWorks web site and review their graphics test results for various video cards and drivers. The link is: (http://www.solidworks.com/swdocs/support/html/videoissues/videotest.cfm) . Once you get to this page, click on the link to "show all test results". If you have one of the cards listed in red or yellow, change your graphics card to one of the ones in green.

You can't fight a hardware problem!
