Nice! The Cg version works on my X800XL now, with some limitations.

Vendor: 'ATI Technologies Inc.'
Renderer: 'RADEON X800 Series x86/MMX/3DNow!/SSE2'
Version: '2.0.6847 WinXP Release'

Changing the "Inside" option gives this, I guess C6003 is a limitation of my card:

CG Compilation failed:
        (114) : warning C7011: implicit cast from "float4" to "float2"
        (114) : warning C7011: implicit cast from "float4" to "float2"
        (0) : error C6003: Arithmetic instruction limit of 512 exceeded; 519
arithmetic instructions needed to compile program

Trying to set Gradient Offsets and Gradients to their defaults with middle click
gives this:

ArrayBoundsError gpufractal.main(265)
