I have noticed that the Vegas at the time of performing the Render does not use the 2nd video card and the RAM is also very low use even with 20GB videos and uses over hard disk.
I found in previous forums that Vegas did not natively use 2 video cards on a single screen since I have a SAMSUNG Monitor 49 inches and when changing the allocation of render by GPU I have problems in previewing the videos.
I've also read that Vegas can not use more than 32GB RAM. Is that true?
