[3dem] motioncorr fails to initialize GPU

[Dieter Blaas]

Dear all,

     I am astonished to read here that Motioncorr_v2.1 appears to run on 
a GPU with just 2 GB (i.e. a K620). Can you please confirm this! 
According to the hardware specifications it needs at least 4 GB of GPU 
memory and I tried to run it on a GeForce GTX 660 and got error 
messages. Could it be that this is rather related to the fact that I 
have cuda-7.5 instead of 5.0 as suggested in Michele's posting?

Thanks, Dieter
