HD4890 drivers and weird problem

[khaooz]

So I have the hd4890 graphic driver, and it always gave me trouble installing the drivers for it. It's no longer supported and the last known drivers (that I know of) is the 13.9 legacy drivers.

Problem started when I was afk and I left guild wars 2 open. When I came back the PC had rebooted. I checked the minidmp for one and there was a bluescreen report. When I went back to gw2 my FPS had dropped to 15 (played at 70 average before). It only happened to gw2 and no other game. I tried to reinstall the drivers and now im back to having problems.

Two things happened. I either install the drivers and my FPS go back to 70, but my pc crashes after 1 minute (BSOD with atikmpag.sys error), or I install other drivers and im in 15fps again. Already tried all the drivers I know of: 11.2, 12.6, 13.1, 13.9 even a modded 12.10.
My process to reinstall drivers is Unninstal from device manager, clean the ATI folders from disk, run Driver Sweeper, and reinstall drivers. I reinstalled using the AMD setup and the device manager install, and both those ways didn't solve my problem.

Dunno what else to do really, except buying a new graphic driver (which I really don't wanna do for now)

so the problem only happen with GW2? does it mean other games are fine?

Yep. Only happened on GW2. My temporary solution was getting a modded driver, that seems to work (so far). Only problem is whenever I log in to windows I get a kdbsync.exe missing file error.

well as long as it works in games that's fine. that's the problem when the support officially dropped. some games still need changes in drivers even if there is a patch to fix the game problem. isn't that AMD promise to update the legacy driver section once in 6 months in the past?
