3DF Zephyr wont use zluda

[Wallcutter]

When I launch Zephyr with ZLUDA it only hits the CPU. Zephyrs "System Info" only shows "AMD Radeon 6800XT [ZLUDA] memory" which stays constant during runs. The Benchmark says "No CUDA GPU found".
Since the Benchmark times are consistent with a CPU only run, it cannot be only a reporting error.
(When using Zephr even with a 1030 the times are faster)
Does anyone have Ideas why that could be? Any Driver issue that I am unaware of?
Running with a Intel CPU, having a 6800xt and usually either a GT1030 or a GTX970 installed.
