Cooking/Packaging with 64-bit

[O_and_N]

Hey peoples,

All this time I accepted the fact that UDK is 32-bit only but I’m working on optimization at the moment and I noticed that I can get a significant performance boost just by using the 64-bit exe (4-10 FPS depending on the situation)

As I’m not using any dllbind I’m safe in that regard, and whatever claims I’ve read about the 64-bit exe being incomplete haven’t affected me at all (all this time I’ve run the editor and PIE with the 64-bit exe, and I know for a fact that the full-license UE3 has no issues related to the 64-bit exe as we shipped HeroesVII at work with it).
So I went ahead and tried it.

UnrealFrontend only has this Shipping_32 profile but all UnrealFrontend is really doing is launching commandlets in a convenient way.

So here’s what I did:
I modified UnSetup.Manifests.Game.xml and UnSetup.Manifests.xml from the Binaries folder, and I replaced every occurrence of “Win32” with “Win64” (and to be double-safe, replaced “Win64” with “Win32”)
And then I packaged my game.
I then installed the game using the created installer, and launching the game properly launched the 64-bit exe. running it in windowed showed “64-bit” on the window’s title bar.
so yay, it works.

for now I was using the data I had previously cooked with UnrealFrontend. at some point later I’ll try to re-cook everything using the 64-bit exe, by launching the commandlet manually from a bat file, like so:

start Binaries\Win64\UDK.exe CookPackages -platform=PC EG-Entry.udk EG-Menu.udk EG-Training.udk [and the rest of the maps one by one] -full -multilanguagecook=INT

however I dont feel like cooking the data with the 32-bit or the 64-bit exe will make a difference.

anyone tried any of this?

Sorry for the necrobump Mate.I just modified the UnSetup.Manifests.Game and UnSetup.Manifests with win64 as you did and did a cooked game.After installing it I hit the ok to start and the game did started in x64bit mode.After I exited the game I went to the installation folder and noticed that in the binaries there was no win64 folder, so I had to manually copy/paste the win64 folder from the udk editor and copy it in to the binaries of the game so that I can launch the game in x64 bit once again.So by default, no win64 directory was cooked in my case.Did this happened to you too?
