SimonJM :

The DLL is only to work with the correct running version of DS, but yes, the program is 32-bit, so no matter how much RAM you have you will never use more than 2 Gigs RAM for this x86 program - It is not Large Address Aware, so is capped at 2 Gigs.

However, I just tested (ver2 demo EXE) making the program LAA which gives the maximum x86 cap to 4 Gigs RAM on a x64 system. I only tested the included plane/sphere testing scene to confirm making the program LAA works or not.

I used Large Address Aware-2.0.4 to enable the LAA.

Now, this is old from pre-GPU days, and is in regards to CPU usage - I am not sure how this affects GPU usage, or if springs are only being stored in general RAM, which is where the cap comes in. Gérald will have to confirm the differences/usage allowances.

My suggestion would be to make it LAA, re-run your animated sim, and see if you still get the out of memory error on springs creation. Using 'Spring reduction' (check box) in Scene Import Tab often helps as well.

• EDIT: I know you said it gets to 800MB in corner, but from what I remember testing/using version 1, there is initial spring creation, and then compounded spring creation depending on different settings enabled - you might only see the initial springs creation reported, and the out of memory error due to further springs creation for the animated drape -- Corrections for this, Gérald/Dan - I could be wrong.
