How does Texture Resolution affect texture load rates in particular?

Featured Replies

Anyone understand how Global Texture Detail settings of 1024x1024 versus 4096v4096 would impact the P3D V2 rendering behavior?  Never been sure what this variable does...

 

Thanks!

It's for objects that use mip maps

 

Example - If a Plane or scenery texture has MipMaps that start at 4096 and progress down the scale (2048, 1024 etc) and you set Global Texture Resolution of "1024", your plane will only display the 1024x1024 textures and not up to 4096..

Thanks for that.  And if you will...

  1. I think I read that scenery textures in V2 start at 1024x1024, is that your understanding?  
  2. If you set GTR to 4096 does this perhaps reserve VRAM address space that becomes effectively unused when most textures are 1024x1024?
  3. Do you know if there is a performance penalty, specifically texture load rate performance, incurred if you have GTR set at 4096, for example to cover airplane textures that might go that high? 

​I'm seeing the texture load rate I had in FSX was pretty similar to this if not better.  I have GTR at 4096 in FSX too.  When I say 'texture load rate' I am referring to how quickly textures load to their highest resolution.

 

Lots of questions so thanks in advance for sharing your insights ;o)

Another question from me.

 

I have looked in the scenery and aircraft folders of the default P3Dv2 installation, and i can`t really find any native 4096 textures anyway, so is this setting only applicable to add-on scenery/aircraft or am i looking in the wrong place ?
