Hi,
My question is quite simple :
In the case of a Deferred Renderer, should Normal / Depth texture use Point Sampler ?

That's how I did it, it didn't make sense to have the hardware interpolate normal vectors or depth values, but I also have a 1:1 ratio between my backbuffer sizes and my G-buffer RTs, so I guess it didn't matter.

Most sane G-Buffer setups need to be point filtered . Also, Any non g-buffer textures fetched will also need to use tex2dlod instead of tex2d etc, as the hardware is going to do weird things computing which miplevels to use.
