Ventuz Performance with huge DDS

Post by Poly Kim » 05 Oct 2014, 07:39

hi, all :)

I need to use a DDS in ventuz and its size is 20000 * 10000 px.

Any idea what I can get stable performance?

The file size is 254 MB.

Please feel free to let me know as for it's about image size.

thank you
Poly

Hi Poly,

You should check the texture size your graphic card is able to manage.
You could split your big texture according this max texture size.
This will be more performant.

Regards,

Rob

The maximum texture size is 16384 x 16384 pixels. This is the same for all current hardware and for DX9, DX11 and OpenGl. Unfortunately there is little indication that newer hardware will move this limit up, because it depends on the precision of the 32 bit floating point arithmetic used by the GPU, and that won't change any time soon.

Be sure to use the Texture Loader node and not the Image Loader, as the Texture Loader has a special optimization for DDS textures.
