Hey;

 

I noticed that the system requirements for the DCS A-10 is a 64bit...I have a 32bit will it still run????? :music_whistling:

 

Personally, I would not recommend it but it will run.

ASUS ROG Maximus VIII Hero, i7-6700K, Noctua NH-D14 Cooler, Crucial 32GB DDR4 2133, Samsung 950 Pro NVMe 256GB, Samsung EVO 250GB & 500GB SSD, 2TB Caviar Black, Zotac GTX 1080 AMP! Extreme 8GB, Corsair HX1000i, Phillips BDM4065UC 40" 4k monitor, VX2258 TouchScreen, TIR 5 w/ProClip, TM Warthog, VKB Gladiator Pro, Saitek X56, et. al., MFG Crosswind Pedals #1199, VolairSim Pit, Rift CV1 :thumbup:

Little known fact:

 

Vista and Win7 both ship with an x86 and x64 based disk. If you still have your license key, you can download a 30 day trial x64 disk and install it using your license. And you should move to a 64 bit system, that way you dont waste any resources with your computer.

Win7 Ultimate x64 here...You really get the impression that the 64-bit (12 lane freeway) is being used in this sim. So many calcs going on at once and you can maintain performance. Definatlety a great example of 64-bit coding.

The 64 bit spec is more to allow for higher memory use. With 32 bit you are limited to 4gig of ram, that includes the video card memory.

In general: very wrong. Only if you have a gpu that uses shared memory.

He's not wrong. Addressable memory on a 32-bit desktop version of Windows is limited to 4GB. This is reduced by the address space used by devices such as video cards. (which could be signficant nowadays). The address space of the devices overlaps with the address space of the "physical memory" ("RAM"), making part of the physical memory unaddressable.

 

Address space per user-mode process (applies to "supported" versions of Windows):

32-bit app / 32-bit Windows / app is not "large address aware" (= default): 2GB

32-bit app / 32-bit Windows / app is "large address aware" and /3GB flag is set: 3GB (or between 2GB and 3GB when using USERVA switch)

 

32-bit app / 64-bit Windows / app is not "large address aware" (= default): 2GB

32-bit app / 64-bit Windows / app is "large address aware": 4GB

 

64-bit app / 64-bit Windows / app is "large address aware" (= default) : 8TB

64-bit app / 64-bit Windows / app is not "large address aware" : 2GB

32bit windows can only address a 32bit memory space.
This is not valid for some server versions of 32-bit Windows (Enterprise and Datacenter editions), which can use up to 64GB of physical memory using "Physical Address Extension".

As far as I can remember the application still must reside within a 4gb address space, even with PAE. IIRC PAE provides multiple 4gb address spaces, not a contiguous space larger than 4gb.
