I have been using an HP 27" All-in-One with the integrated graphics card running R40 and no issues in terms of control and performance. I just purchased a LENOVO laptop with an NVIDIA GTX1050 card and the performance difference is AMAZING! However, my CHAUVET ROGUE R2 fixtures are in a constant, never-ending VERY slow motion. I inserted new R2 fixtures and they do the same thing. Nothing in my session file in JANDS VISTA has changed, nothing in this file in WySYWYG has changed either. I am running the session back on my desktop machine and it runs PERFECTLY FINE. Both machines are running WINDOWS 10 HOME, 64-bit.
