Epsilon
Min:
0.05
Max:
0.5
Result...
PS
Also, w/ this file I noticed that whenever I made a larger/broader
Epsilon change, CUDA recompiled from scratch.
Didn't do it systematically, but at random... if anyone is willing to check.
Another thing is an error report (using mentioned values):

PS.
@Dez!
I would advise to retopo/remesh your geo to prevent such headaches in the future. Elongated (long edged) polys are known to cause shading issues.
Keep up the good work.

PPS
-
Epsilon Max 0.1 works fine (default)
- CUDA recompiles from scratch whenever
Epsilon Max. value is changed
- full log attached
