HOLY HELL !!! EVERYONE ON THE ECYCLES HYPE TRAIN RIGHT NOW !
Barcelona benchmark
CUDA 1x 2080ti ----------------------> 3:43.92 => 1x

+There’s a lot of e-cycles features missing tho, the final build is going to be even more faster
I got a LOT of crash tho, the build is for now really instable.
here is the crash error
