My Radeon experiences :
First my system : KT7-RAID, 1.1gig T-Bird running at 1250 With Peltier/Alpha, 256PC133 Siemons/Infinity, Radeon 64meg VIVO, Adaptec 29160 scsi, 15,000rpm U2LVD Cheetah & three other 10,000rpm Cheetah's, SB Live, Plextor 12/4/32, Plextor UW40x, Toshiba 1212 DVD, scsi zip, two Firewire cards, HP parrallel printer, HP USB printer, TV tuner, 3COM nic W/ Motorola cable modem & Linksys 4 port/router/switch, 56K Phoebe, scsi scanner, USB Smart Media reader, Klipsch Promedia's & 5.1 surround sound, Viewsonic P815-3 21", MS FF Steering Wheel & FF Joystick.
I triple boot W2K, Win98SE & Windows Advanced server. I'm not a huge gamer, but my son is. I love Porsce Unleashed however. I use Win98 exclusively for gaming & W2K for everything else. I have used W2K from the day it came out & I love the stability of it. With all this hardware, it is MUCH easier to get it all working with no conflicts in W2K than Win98. When I had a gts card in my system, W2K worked great for gaming also. The Radeon is by far the best card I have ever used in Win98 & I've tried them all. The image quality is actually better than the G400 Matrox I had. It is giving me fits in W2K however.
I have tried every driver released so far including the new beta & none of them work correctly with my monitor driver. I can't install the Viewsonic driver, so it's stuck at a refresh rate of 60 which gives me a headache. I can use any resolution I want & it lists refresh rates up to 200, but they all look exactly the same. It says "default monitor" in the display properties & it won't let me change it. There is no monitor at all listed in the device manager.
This is a known problem & there is no solution at this time. I threatened to take the card out, but my kid had a fit. It works so well in Win98 that I am going to live with it for a while & hope ATI gets the W2K drivers straightened out. With ATI's track record for driver support, I'm worried that may never happen however.
At this time, I definitely wouldn't recommend that anyone who uses W2K exclusively for gaming buy this card.
