The game is still limited to 2.5GB and freezes when it hits this limit

[GunnzAkimbo]

Using Elys-Meminfo, i loaded my save game in whiterun.

 

then i ran up to skyforge, and stood on the edge looking at the city.

 

The ram was sitting on 2000MB'ish

 

now, i started spawning storm dragons, 1 at a time.

 

i was watching the counter go up slightly, each time a dragon was spawned, and manage to spawn about 15 dragons, maybe 20 (wasn't counting)

 

i ran around for a bit to try and make the game work a bit harder with random scenes (it was bloody chaotic anyway with all the fire and lightning shooting all over the place), and as i was running up the stairs to dragonsreach, it froze, at the same Memory limitation of 2500MB'ish

 

i did this 3 times in a row.

 

i patched the game to the latest update, and even patched it with a LAA patcher (AFTER the first crash) with a windows app (i use it on all sorts of apps (eg Paint Shop Pro) and they address way above 4GB of ram - I have 24GB of ram in this PC)

 

So, the game is still limiting something, perhaps it's limiting a TEXTURE cache in memory to 2.5GB... perhaps the patching scenario beth made can use more data processing memory addressing like loading levels from memory... IDK but try this test yourself.

 

I use MANY 4k texture mods, and the game is STABLE for many many hours just playing normally, but i wanted to test its limitations on memory usage. The dragons have a 4k texture mod, so we have 20 or so dragons flying around using heaps of resources.

 

My vid cards are 1.5GB 480GTX in SLI, and the GFX settings were maxed on Ultra, View distance Fade on Maximum levels, 2xAA, 16xAF, 1920x1080, running on a 4.4Ghz i7-980 with 24GB of 1600Mhz Memory. The system is STABLE, there's nothing wrong with the PC, it's the game that's wrong.

 

The game works fine if i play normally (bet someone doesn't catch this) and it can last for many many hours stable, going anywhere on the map.

I don't care how much you patch a 32-bit EXE, it's still only going to be able to address 3-4 gigs of ram.

64 bit OS will address 4Gb ram for a 32 bit application. The Skyrim specs state using a DX9.0c video card.

 

Under DX9 the OS maintains a virtual copy of the video memory in primary ram.

 

To quote Microsoft:

If an application creates its own in-memory copy of its video resources, or the application uses DirectX 9 or an earlier version, the virtual address space contains the WDDM video memory manager's virtualized range and the application's copy. Applications that use graphics APIs that are earlier than DirectX 10 and that target GPUs that have large amounts of video memory can easily exhaust their virtual address space.

 

This doesn't happen from DX10 onwards, and if Skyrim is using DX10+ it may have been developed under DX9.0c and badly ported over to DX10 and not utilizing the later memory management. Not an uncommon thing apparently.

 

In short, addressable space is 4Gb, 1.5Gb of VRAM is virtualized into that 4GB leaving you with 2.5Gb usable for the application. That seems to tie in with your results.

 

DX reference: Virtual address space usage in Windows Vista game development

 

PS. Win7 is built on the Vista core, so any reference to that OS is good for Win7

Yes I have tested this myself in Visual Studio 10 on Windows 7 64bit

Made a little 32bit app that creates 4 Data Arrays at 1gb each

App crahes unless i use the CFF explorer and set - APP can handle > 2gb Address Space

Works fine with 4gb

Add another 1gb data Array for a total of 5gb and app crashes.

 

4GB is the limit!

 

Still i,m finding Skyrim crashes a lot when it passes the 2gb limit, perhaps they have other problems associated with there supposed 4gb patch!

I have been having the same problem with my "large address aware patch" the game is still capped under 2gb,

shutters when i enter a town or just doing 180 look arounds,

at first i thought i downloaded the wrong 4gig patch so i tried them all with re-installs but none will let the game use more resources.

i have a half a dozen large HD texture mods and they stated they use more resources but i not seen a increase,

my rig is not as high spec as gunzzakimbo but should be able max out everything.

 

just seeing if anyone else is having the same problem or am i just crying over milk,

Thanks for the information Nekrafilia. Ive been wondering exactly what all this tomfoolery was about.

[rabidNode]

I have similar issues. The game is not coming near its 4gb cap and often not even 3gb before crashing out. I have 64 bi. The above explanation with dx9.0 makes a lot of sense here.

So hopefully we will get a mod next that will optimize the port to dx10+

[noae86]

i have the game running on my new laptop and gaming desktop but with same resource cap, i hope something can be done in future updates, its silly making such a great game and strangle it like this,
