Watch Dogs Minimum PC Specs - briefly

(hx) 09:15 AM CET - Mar,13 2014
The minimum PC specs for Watch Dogs has been posted online. Overall it looks like folks running lower-end hardware will still be able to run the game somehow: Intel Core 2 Quad Q8400 2.66Ghz or AMD Phenom II X4 940 3.0Ghz 6GB RAM 1024 VRAM DirectX 11 Shader 5.0 Soundcard DirectX9 25 GB HDD space

how are they planing to utilize 6GB of ram on a 32bit executable that can, in best case scenario, allocate up to 2.5GB of ram?

With PAE?

Csimbi> With PAE? cant do. if you run 32 it0 you run 32 bit. You cant install 64 bit on top of 32 bit and hope it works.

Here:
quote:
The original releases of Windows XP and Windows XP SP1 used PAE mode to allow RAM to extend beyond the 4 GB address limit. However, it led to compatibility problems with 3rd party drivers which led Microsoft to remove this capability in Windows XP Service Pack 2. Windows XP SP2 and later, by default, on processors with the no-execute (NX) or execute-disable (XD) feature, runs in PAE mode in order to allow NX.[14] The no execute (NX, or XD for execution disable) bit resides in bit 63 of the page table entry and, without PAE, page table entries on 32-bit systems have only 32 bits; therefore PAE mode is required in order to exploit the NX feature. However, "client" versions of 32-bit Windows (Windows XP SP2 and later, Windows Vista, Windows 7) limit physical address space to the first 4 GB for driver compatibility [10] via the licensing limitation mechanism,[9] even though these versions do run in PAE mode if NX support is enabled.
So: Install XP with SP1 only and hope that your drivers won't go nuts.

cant do. if you run 32 it0 you run 32 bit. You cant install 64 bit on top of 32 bit and hope it works.
Huh? PAE is 36 bits (32bit+PAE=36).

Huh? PAE is 36 bits (32bit+PAE=36).

you don't understand, addressing more than 4GB of system memory is one thing, having a single application use more than 4GB is another thing. And like I said, you can't use over 2.5 GB per application on 32bit (36bit gives just a little bit more, I used PAE on XP back in the day, I use photoshop for a living, I used it back then, max memory it could allocate with PAE was ~2.8GB if memory serves me) system even if that system has 128000 gigs of addressed and reported ram.

PS. PAE is not needed anymore, XP couldn't allocate more than 4GB, windows 7 32bit can allocate 8 GB, doesn't need PAE, still, you can't use more than 2.5GB per application :)

PPS. As a matter of fact, you can have a 64bit windows but if application is 32bit coded, it can't allocate more than 2.5GB.

This is not entirely true, but it's a good rule of thumb. well I don't know the exact numbers it's somewhere there, 2.5GB. With PAE I think it was possible to get up to 3GB but that's still far from 6GB as proposed in min spec for watchdogs, and PAE isn't really a thing nowdays...
