How do I use the Eevee and the Cycles engine simultaneosly? (for the same output video) 1:24

Plus, I checked, changing the GPU  back to CPU doesn't switch to showing the  X, Y coordinates. And Yes, I had a default cube on the scene!... So , if you could explain  this  I would appreciate it!

then under Tiles it states 'Tiles X  as 64 and Y as 64 . 'Other'  as  'Herbert Spiral' ,  then Progressive Refine  with a Box.   How do I  make adjustments  if I  don't see Tile size coordinates?  It only shows  the larger '2048'? Where is Tile Size adjustments located?

Hi. Ok I will attempt to explain:  Under Quick Overview Cycles Render Engine. Then under Performance, Tiles.  Following along I selected Cycles, GPU, Performance, Threads... [This is where Blender 3.0 is different from 2.8 Fundamentals Tutorial.]   Blender 3.0 has 'Memory' with  an  box to check ' Use Tiling' and 'Tile Size' with   '2048".   2.8 Fundamentals has   Performance, Threads.....'Tiles'

Hi , I have a situation I need help with.  It’s on this lesson. Before I explain my question, I need to know how to upload two photos to show what my issue is.

Thanks!
