✍ Ostinato performance indicators explained
|
| FPS: | Frames per second. When -swap:0 command line argument is passed, it can be used as a general system performance indicator. |
| EXE: | All the objects 'execution' work - control program execution, motion calculation and blending, collision detection. Setting -nwrk command line argument to N > 1 will enable parallel execution of those jobs by N workers. EXE time also includes camera program and collision time. |
| VIS: | Scene objects visibility culling. |
| DRW: | Time spent on executing code drawing models, primitives (such as pseudoshadows and sprites) and UI elements. It includes OpenGL function invocation time. |
| GPU: | GPU frame execution time obtained through OpenGL timer queries. Not available for some GPUs. |
| SUM: | EXE + VIS + DRW + GPU |
