16bg ddr3 = insufficent memory?

[backgamon]

Hi,

Some games have a little problems, it says "Error! (HRESULT = 8007000e) Failed create buffer.

If i have another program loaded win7 x64 quote "Insufficent memory please close some programs", but in task manager i have only 15 at 20% used o_o

Currently 2 games doesn't work - Soulcalibur and Wacky races.

All working well on 0.5.7 , but crash too on 0.5.8-2.
Allready tryed the uninstall/install, no luck.

Now this time i can take anything from my configuration (i don't delete ).
Tryed with lowest setting too, all other games run in 3x/32layers, but tested with lower res/layers.



EDIT:For Wacky Races lowest layers (to 16) seem to work finally -> re-re-retry and i finally getting to work, but for Soulcalibur....notting.

Just an idea but maybe patching it with the Large Access Aware program will solve the issue.
I don't use Demul so I can't say that I've tested the idea.
The Large Address Aware program can be found here.

Checked with both 4GB patch and Large Access Aware, but no chance, always crash

this is not related to main RAM, as you can see it says it can't allocate GPU buffer. which size currently in DirectX 11 limited to 2GB. it doesn't matter how much main RAM and video RAM you have, you cant have single buffer bigger than 2GB.

I'll gave you simple equation for almost all games:
640 * 480 * 16 * MaxLayers * Int.Resolution * Int.Resolution

in the case of 32 layers and x3 it will be ~1.4GB buffer of video memory needed to be allocated (and its not only one, just hugest one).
but, few DC games have its own internal horizontal rendering resolution twice as big - 1280, not 640, Wacky Races is one of such, so it becomes 1.4*2=2,8GB, which is bigger than DirectX limitations.

Wow,

Now it's very much clear.
Thanks for the explanation
