I have to give up on this. The workaround does not work.
Actually this is a very particular restriction of that very particular model (or model range). Cited:
“That particular error comes from the Nvidia compiler for nv4x (GeForce 6/7 cards), and is a limitation of the hardware.
All versions of GLSL support indexing in the language – this error falls under the catch-all of exceeding the hardware resource limits.”
So, bottom line is, the VST Connect message box was right to say “Your Graphics Hardware or driver are outdated”. It’s a pity because it’s kinda nice card with 4 monitor capability.
As said, any other (reasonably new) graphics card should work. I have several older models which don’t expose any such problems.
Really tried my best, but this can’t be solved, sorry.
