I only use Resolume now and then when I need to slice for LED screens, my usual route is Barco S3 with 1 big wall, but I have noticed in the past that when i am using Resolume the screen has felt a little soft compared to what I am used to but never had the A/B setup to check it and just excepted it is probably my eyes...
I've gone back through different versions to check if this has been introduced recently but the same results on all versions back to 7.2.0 (I haven't gone back any further!)
