Dear VMD users,

while starting up VMD I get the following error

Info) Creating CUDA device pool and initializing hardware...
CUDA error: out of memory, line 91

GPU-Z reports that about 200 MB of the 1024 MB are available on the GTS 250
before I run VMD. Afterwards there is no significant change in memory
allocation.
The problem goes away if I turn the AERO interface (GPU-Z reports only 32 MB
of memory allocated).
I have installed the newes CUDA drivers (190.38), but the problem persists.
As soon as AERO is active I get the out of memory exception.

Does VMD really need more than 800 MB to function or is the error somewhere
else?

Best regards,
Ajasja Ljubetic
