Why do you think Lumion is not using the dedicated GTX 870M card?
Please update your forum Account with your Lumion 5 license key (click here
, scroll to the bottom and enter your license number). Thanks in advance.
I would also recommend updating your Lumion version to the latest V5 which is V5.7.2.
ps: I have deleted your earlier duplicate topic
