Fix For Sparkling Spots In Unreal Development Kit

UPDATE: 12.3 breaks the editor when you’re using these old dlls.

You could probably expand the rest of 11.2 and put it into the binaries folder. The game mode is still fine, so just the editor is affected like the above screenshot.

It appears every driver after Catalyst 11.2 has a bug in Unreal Development Kit. I would have noticed this sooner if I used UDK more often this year. I don’t know how many cards this affects, it might just be for older cards. I’m on a 4870×2.

Anyway the solution is simple, put 11.2’s dx9 dlls into the binaries folder of UDK. Installing the whole 11.2 driver set for the whole system is not a useful workaround, since most people would need fixes or performance gains seen in newer drivers.

So grab the dlls, then place them into the appropriate folder:

For the 32bit editor and game: put atiumdag.dll into \Binaries\Win32
For the 64bit editor: put atiumd64.dll into \Binaries\Win64

If you’re using RadeonPro to force crossfire profiles, it will overwrite the dll that you placed, so you’ll have to use the driver version compatibility feature to use 11.2’s dll. I would instead just make a copy of and rename the 32bit UDK.exe into AliceMadnessReturns.exe to get crossfire scaling when launching the game.

    yes its that :) are you testing for TwL?

    do you know when new driver will be released from TWL and if yes, will be good for HD4870x2 or TWL will focus more on single GPU or new gen. cards (HD5xxx/HD6xxx)?

    Do you use TWL modified drivers? if yes do you know if genetix_build510 version is good for HD4870x2 or genetix_final350_cfx_105 is better?

    @Daniel i only use WHQLs & sometimes dlls off other drivers, never checked TwL’s but read the thread, you should just ask there

    […] to AliceMadnessReturns.exe. Make sure to have the latest CAP, and it still works even with my sparkling spots fix, which uses 11.2 […]
