  1. Actually a large majority of computers has got GPU. The problem is that blender uses cuda that is only for Nvidia. Intel or Radeon users need opencl that is open source but the support from blender is not available (or with testing options but that doesn't work for the majority).

  2. At 6:32 I turned on auto tile and then I am having problem to render anything on blender with GPU. My gpu model is GTX1050ti.
    I always get this error.But if I use cpu I can render please help.Error that I am getting
    "CUDA error: illegal address in cuCtxSynchronize(),line 1372"

  3. You missed one of the most important optimizations: Scene > Simplify > AO Bounces Render. Set it to 2 for scenes without things behind glass and 3-4 if you have lots of glass. Then, you can set your samples to 5 min 5 max for best results. The AO Bounces setting treats all materials as diffuse after X bounces and it reduced the render time of my short film (see my channel) to a half of the previous time.

  4. Just a note: all those optimizations depend on what you are modelling. Transparency should be taken with utmost caution, without some settings or with set too low, they appear either completely black or rough and clouded.
    Denoising also may cause artifacts, that could be fixed in photoshop but sometimes its better/easier wait a little longer for denoisier to blur noise properly rather than seeing fireflies, especially on animations.

  5. 1st get rid of the jazz piano playing the whole time . 2nd get rid of having yourself on screen talking the whole time. Makes no sense to have a 2nd audio and video on top of what your presenting . You my as well  put a 3rd in there like a TV playing too the whole time it is just so stupid!
