render time with ETA & progress per subframe #178

Closed 3Dickulus closed 3 years ago

3Dickulus commented 3 years ago

Description v2.0.0 is much faster when rendering the default fragment due to differences in progress updating

To Reproduce

  1. comment out all progress update code in void DisplayWidget::renderTile()
  2. move current exe to ./Fragmentarium-2.5.5-old
  3. compile new executable
  4. compare tile based hires render times time ./Fragmentarium-2.5.5-old -s ./fqScript/testFrag.fqs && time ./Fragmentarium-2.5.5 -s ./fqScript/testFrag.fqs
  5. observe duration

Expected behavior The difference in times should be minimal
