My ATi experience.
I have been reading a lot about how ATi's drivers have improved, installers improved etc.
I bought a Radeon 7000 for my wife's 'puter because she does a lot of 2D and I wanted great image quality without Matrox's price. 3D wasn't a concern.
Loaded the Radeon drivers and away we went. ATi's 2D quality was noticeably better than the GeForce2 GTS 64 (Hercules) it replaced. Colours crisp, text sharp at 1024 and up to 1280 on a LG Studioworks 76i (1024 @ 75Hz - shadow mask) and a Mitsubishi 19" Flat (Trinitron, aperture grille - 1024 @120Hz, 1280 @ 85Hz).
Where ATi drivers suck. This is on a W2K machine.
ATi's installation instruction say - remove existing driver, install VGA driver and then (and only then) install new/updated driver.
In Windows 2000, you can't do this. There isn't a VGA driver. Go look
Even if the (ATi) driver has been uninstalled - the *.INF file is still their, so everytime you reboot (after "removing" the driver), the bloody machine picks it up again and instlls the driver. ATi says cancel the install,
but W2K doesn't give you the option!
When you go to install the new driver - hoping everything will work out - ATi's install routine says a previous install has not completed and craps out. -> aaarrrggghhh!!!
Install in safe mode - nope. See above. Old driver is still hanging around.
Tried replacing the ATi card with a Kyro and that's when I found out W2K doesn't have a VGA driver - one is there as a fall back, but you can't install it and make it stick. As soon as I put the Ati card back in, W2K found the old driver!
Work around - find the OEM.INF file with the ATi details (in %system%\INF folder) - delete it. Find the compiled OEM file (PNK??) and delete it.
Reboot
Install new driver.
This worked. It took me 4-and-a-half hours to update a video driver that only wanted to refresh the screen at 60Hz.
Not quite up to NVIDIA standards yet. But the image quality is superior to a GeForce 2GTS and slightly better than a GeForce4 (you'd have to do a side by side comparison to notice) at least up to 1280 resolution.
Hey if anybody knows a simpler way to update ATi's driver, I'd like to know about it.
