GTX 1080 and Vray RT

[Nicinus]

You either don't utilize fully the GPU or you get sluggish UI. If you don't utilize the GPU well it can get much slower ... You can go for lower utilization with RT GPU with rays per pixel 1, but for many scenes it is not low enough. I am thinking of adding option for that on-purpose underutilization. I will count your post as a request for that .

Any more thought into this? I just have a hard time understanding why this works well for Redshift/Fstorm but not for us?

I'm also curious about this technology where the GPU can utilize RAM memory when you go over the board's. Is that something that are being considered? It would seem that paging against slower memory is better than not being able to start the scene at all?

no i figured out that it needs a system reboot when swapping which GPU uses the display.

Maybe you still have it checked on 1080 so the 1070 isn't used at all?
