Hello all, by following the very active community you have set up for the scene of flashing PC cards to work under OS X I myself bought a 4870 XFX ZWFL & ZWFC 1GB and flashed it. This occurred about one month ago, and since then the card has been working flawlessly, so a big thanks for that. A very nasty problem occurred after the 10.6.3 update tho, as since then I started having horrible fps's in any application that required 3d acceleration (say, World of Warcraft); down from a rock steady 50-60fps (that easily topped the 120 mark) i can barely get a 30fps after the update. I checked the other topics, and all of them pointed me into downloading the last version of Zeus and update the drivers, wich I did for every time an update (or fix for a fix) as been released, and tried every time to install both before and after the reboot from the 10.6.3 combo update. I'm using only one monitor, so I did not encounter any problem concerning dvi ports not working or anything. Any help or suggestion? Thanks in advice.
