@pro-rsoft: regarding the Feb.23rd bundle you made available of 1.6.0-pre, I can attest to that the “Not powerful enough” bug is there (I have a Mac Pro with nVidia 8800/512).
Also, if I enable setShaderAuto(), my project crashes (no sensible messages tho 
)
But thanks for your efforts 
Without you I’d be stuck using an old PC
