thank you very much all. i took my hard drive to the shop where i bought the card. it's not only the issue with SU. my audio system didn't work, i suspected that it's due to the new card i just installed. my assumption was right. the mainboard driver and ATI Radeon driver were conflicted (my hd is HP a5080l. the guy in the store let me change the ATI with the new card. i chose GeForce8500 after reading what's written here regarding the graphic card. it's not expensive, i paid about US$70. tweak a bit in the open GL option, tick the last line to be 4x. it works alright now.

i tried that, still no improvement. now thinking about buying new card, but don't know which to buy, something that suits my demand. i don't want to pay too much for what i don't really need and also don't want to waste money buying something that doesn't work. i am living in thailand. tomorrow will go look for options. i'm not sure if the salesperson would be able to help me pick the right card....

^ where to find that option? in the catalyst controller or SU? thanks for helping.

i just add ATI Radeon HD2600 to my computer, spec: microsoft windows XP professional version 2002 service pack 2, pentium D CPU 2.8GHZ, 2.50 GB of RAM. i had problem orbiting the heavy model before i got the card. now it's another issue, orbiting is fine but when i select the entity, i can't grab what i want.

i tried setting up the anti-alias thing to let the application control, i tried download the latest driver for the graphic card. it didn't help. what should i do? buy a new graphic card? which one would work best ? i do not render, just modelling. anything that makes me orbiting the 50 M file smoothly would be great.

help or suggestion would be appreciated. i'm not a computer guru and need to finish the project i'm working on within this week. thank you.

It works wonder! Thank you, Buckhard. For installation, I didn't do the copy part. Just normal double click at .exe downloaded file, and start using it.
