You could just add noise to the small textures on several different scales so they wouldn't be repeated exactly.

You don't need shaders to do this but I imagine you can do it pretty flexibly with shaders.

Interesting idea, although, I'd imagine that it wouldn't look very good. You would have to evaluate a noise function to do this (which would probably be pretty expensive), and (2) you'd have to threshold your values so that they aren't so drastic (i.e. you don't want a 16x16 texture next to a 256x256 texture). Also, since the textures would share the same uv space on the mesh, they'd look out-of-scale.

GeForce 4 still has RT patch tessellator! Not that it really meters much since they have removed support from drivers. You can check this with older drivers

nVidia removed the RT-patch support in Detonator XP (around Sept 2001).
GF4 cards appeared around Feb 2002.
GF4 supporting drivers appeared somewhere before that.

But I doubt there is a pre Det XP driver that has support for GF4 cards.

Please tell me what driver version can be used to prove this!

Yes NVidia removed RT-patch support in Detonator XP, but only for DirectX. However RT-patches were still enabled in OpenGL (NV_evaluators extension) until 40 series.

GF4 ... supports ... RT-patches

No it does not.
GF3 did but they removed the support from GF4.
Current drivers don't support RT-patches at all.
And it looks like the GF FX won't support it either.

well RT-patch demos still run with the same good performance on my GF4 as on my GF3 (teapot)

they only disabled it in one of the APIs if memory serves me right

Oh, I see.

I only use D3D.
