what the eff!!!

It has the LAA flag set in the .exe. What do you mean?

Works fine on my win 7 x64...

Same here. Sounds like a user error.

You mean the game should be able to use use 294673909264545373906374947662900 GB of RAM just to make happy the crowd that buys ram by the kilogram as a penis size substitute ? :P

I think the poster re-evaluated his "comments" and embassingly withdrew his presence!!

Technically majority of software that runs under Windows 7 x64 is not native 64 bit software anyway.
There are of course some notable exceptions (mostly drivers which need to support 64 bit architecture natively) here but they are few and far in between, even iTunes 64 is still a generic iTunes with 64 bit drivers only.

The trick here is WoW, Windows on Windows (not to be mistaken with World of Warcraft).
It basically uses a mixture of virtualization and other tricks to enable vast compatibility between 64 and 32 platforms.
This is why 64 bit installation is larger than 32, because technically it installs components from 32 bit version as well.

The game installs using 32bit, meaning it does not recognize the extra 4GB memory I have or possibly the 4 cores.

Name other game that does?

It will recognize the multiple cores just fine.

What it will not do is use more than 4GB for itself. If you have more than that, this is still a Good Thing, because it will not compete with Windows for memory, and it will be able to page resources back in without having to reread the disk.

There are not many native 64-bit games. Half-Life 2, Shadow of Chernobyl, and Far Cry are the best known. 64-bit Half-Life 2 was known for having many crippling bugs and was withdrawn for that reason. 64-bit Far Cry has been more successful. CryEngine and Unreal Engine have 64-bit capability.

Developing a game for native 64-bit is a lot of extra work for dubious value, and a number of games that were done in 64-bit were AMD-sponsored demonstrations of their then-new 64-bit technology; they were not done as a result of there being a genuine business case for them. A company that does not have unlimited resources and outside sponsorship cannot be faulted for deciding to use those resources to provide more and better game content instead.

In short, it is not CDPR's fault that the game does not need all the memory you bought.

Wrong. The LAA flag is already set in the vanilla .exe.

I think the OP means that he has 8GB and the game does not use the second 4GB.

But I still believe he has no complaint, since any 64-bit game software will loudly announce the fact in its packaging; since TW2 did not, the only fault is his for making a silly assumption then trying to criticize others because he did so.
