Improving Unreal Development Kit Crossfire Performance

UPDATE: Turn off vsync if you enabled it in the .ini files. Use D3DOverrider with triple buffering instead.

Simply rename UDK.exe found in the Bin32 folder to AliceMadnessReturns.exe. Make sure to have the latest CAP, and it still works even with my sparkling spots fix, which uses 11.2 dlls.

The Alice profile is almost as fast as other profiles like Crysis 2, but without flickering of the water or other artifacts.

The following screenshots are of a 4870×2.

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.

I finally got a standalone UDK game working. I’ll make some kind of a tutorial, at least about the flash resolution buttons.

The main point was to get all of the custom stuff functional and out of the way. Now I can focus on content. Here are the ‘features’:

-standalone packaged installer
-custom splash screen
-custom intro movie
-custom menu background level with matinee camera loop
-custom menu in flash with resolution changer
-custom gametype in 3rd person
-custom map
-custom AO/post process chain
-custom sounds
