How to know whether the graphics card is involved OpenGL'ohms?


There is an implementation of OpenGL in Java JOGL.
Decided that the graphics rendering is impossible in Java to draw a CPU, therefore, appealed to OpenGL.

The question of whether in General the above implementation in Java to make the graphics card think?
How can I specifically fix the load on GPU instead of CPU?

Additionally, where I can read about the specific rendering explicitly sent to the GPU? Interested in how it really works.

How to watch don't know, but OpenGl is essentially a specification, implemented in a specific library that essentially implements the interface between the video drivers and your program, so that OpenGl should not use PERC.
What did you mean about "specific" rendering even with the apparent sending it to the GPU? Explicit about, it really depends on Liby.
On account of the "specific" mean the following: I have implemented some algorithms render up to our own implementation of draw lines. The line is drawn pixel by pixel using setRGB. But the parallel on 8 CPU cores increases performance - fps drops sharply with the increase of simple three-dimensional shapes.
Wanted to know how all the calculations to parallel 8 threads CPU and 640 threads of the graphics card. - Magali_OConner54 commented on July 9th 19 at 13:51
: didn't go into details, but it is supposed to do driver video card, probably nvidia no wonder he weighs in at almost 100 megabytes, so that b handles restore order there, I think is not an option, at least not for the grasp of knowledge and time, and secondly, the video card, its conveyor must take care that your tops were considered in parallel. - marian39 commented on July 9th 19 at 13:54
