non mip mapped tiling performance question

Hi guys,

I am wondering if there is any significant performance implications by using a small detail texture, eg. 128*128, without mipmaps, but tiled across a large terrain, this really helps distant detail in my game.

I am targeting mobile platforms, so far from my testing/profiling it seems fine, but I am just wondering if this is bad practice or not.

 

If its such small texture - it doesn't really matter I think. On a larger texture it will probably have some rendering overhead.

I'm using similar approach but on PC. On a really large scale terrain (1.5x1.5km) disabled mipmap of 1024x1024 consumes about ~0.5ms of rendering thread on GTX1050TI. (No culling, everything rendered)

It really depends on the hardware and the texture size. So profile it. If its fine - leave it be.

 

Cheers, thanks for the info! My main concern was if there was something under the hood that caused some bizarre issues or something.
