How can I check which video card is running a particular program?

Question

Video cards

He wrote a video from the elections in "four hands" (four copies), the Video Observer program . The laptop (Asus u32vd, i7, 8GB RAM, SSD, Windows 7 HP) sat down, I must say. Moreover, in terms of performance, it is a “stone”. But in my model, a 1 GB NVidia card seems to work well, for testing I run the Magica game (there are no others), it believed on the old laptop, but it works well on this one.
Actually, this is the first time when my laptop "gave slack" on the stone, usually there is not enough memory. I have a feeling that the program used the integrated graphics. How can this be clarified? Before that, I didn’t work with video at all (I only uploaded it to a pipe), maybe this is a normal state?

Answer 1

Video cards are equipped with chips for video decoding so that any video viewing in h.264 does not load the CPU. But there are no hardware encoding chips, because if everyone is the first to watch a video on their computer, then God forbid, if every hundredth encodes it.
So that's right - all the work is on the shoulders of the CPU.

Answer 2

In the standard nVidia control panel (you have a GT630M, don't you?) it is possible to select the video card used for each individual software, and the required profile has already been selected for popular programs. Verify that GT630M is selected for Video Observer and not "Intel HD4000 Integrated Solution".
Perhaps it will help.
