Sorry, for bringing this back up again. Do we have an actual solution for the Optimus drama yet?
I just received a new DELL XPS 15 laptop which basically is unusable with V4, very likely due to Optimus Technology. I’ve been googling and hacking the Windows registry for several days now, but V4 just doesn’t do what it’s supposed to do.
I think I will have to send this laptop back and shed some tears about it, because it is really a nice and sleek machine. It’s a shame, because there is no real alternative! Do we need to stick to 5 year old technology with V4?
What’s going on?
1.) Rendering on the discreet graphics card does not work.
As soon as I tell the system to use the Nvidia GT750M graphic card for running V4, nothing is visible in the renderer. It just stays black. Interestingly, setting the renderer to fullscreen brings the content back, back to windowed mode > back to black. (reminds me of a good Amy Winehouse song? “Back to black”?)
2.) Multiscreen rendering does not work. As soon as I connect more than one screens to the machine and put renderers there, everything just starts messing up badly. flickering and weid display glitches on all screens. Settings in the NVIDIA Controlcenter “Optimized for multiscreen rendering” don’t do anything to solve this.
3.) System scaling does not work. (not sure if this is related to Optimus?)
As soon as I put a renderer to Fullscreen and back > the scaling options of the OS as well as the V4 GUI get’s scrabled.
I found a thread which points out a registry entry called MAXIMIZEDWINDOWEDMODE. This entry just keeps coming back when deleted and resetting itself to 1 when put to 0.
I really hate to send this machine back.
