CS4 detecting my old graphics card? Jagged lines with new 6850? - Page 2

I have been having the same issue since upgrading from 2xATI 4850 (one died) to an HD6970. Many programs (Including Photoshop, and a whole bunch of games) still detect me as having an HD4800 card. Moreover, the new anti-aliasing modes that were added since the HD4800 series are not available to me in Catalyst. There may be other missing features that I am not aware of.

After digging through the registry a bit, I did find this.

In this key
Code:
HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\WindowsNT\\CurrentVersion\\Winsat
Is the value
Code:
PrimaryAdapterString
Which contained the data value
Code:
ATI Radeon HD 4800 Series
So this value, at least, remained from my last card. If there are other registry values that also remain, I don't know. I have a feeling that you will find the 5700 in that value/data pair.

I'm thinking of using sysprep to generalize my system, and then re-installing catalyst and see if everything is fixed. Will probably do that this coming weekend, so I'll tell you how it goes.

Okay thanks, would definitely appreciate if you respond back as to how you fixed it.

BTW, impressive for a first post.

OK. So, here is the report.
First, I was 100% successful in resolving the graphics card issue. The precedure is not without drawbacks and not for the faint of heart however.

WARNING: This procedure involves running the sysprep tool.
This tool removes all hardware specific info from windows, (as long as you check the "generalize" box) which is what you want. Unfortunately, it is meant for PC manufacturers before shipping, so it can clobber your user account info.

I highly recommend deactivating Photoshop and other software that has limited concurrent installs prior to running this.

Preparation: (Helps in the last step)
Download latest Catalyst and any other critical drivers (chipset, Ethernet) and place the installers in a safe folder that isn't in a user folder. I recommend "C:\\drivers" in this case.

1st, (Probably unnecessary, but just to be safe)
Removed catalyst, uninstalled driver, and ran driver sweeper.

2nd,
Open an administrator command prompt (run as administrator)
Code:
cd \\windows\\system32\\sysprep
sysprep
Choose the "generalize" box, and OOBE. One user account will be preserved as the new system default. There are some rules as to which account will be preserved, and this can be overridden by creating a configuration file prior to running sysprep. I didn't bother. If you want to, there are a lot of guides out there for using sysprep. If sysprep crashes, see the note below. Even if it still crashes, it may have done enough of it's job for this to work.

3rd,
After reboot, you will need to re-install a lot of drivers. Basically, anything that Windows does not have a built-in driver for, will need re-installation.

That's pretty much it. My computer now sees the HD6970 as my graphics card.

NOTE: IF you find that sysprep is crashing, sometimes killing WMP processes and re-running will fix it. You will probably need to press "Show Processes from All Users" in the Task Manager to kill all the bits of Windows Media Player.
