4k monitor slows render?

[fadoogen]

Quick bozo question....

I currently have a 1080 monitor hooked up to an NVIDIA GeForce GTX 680 4096 MB on a MacPro 2009.
If i go ahead and purchase a 4k monitor and connect it in place of the 1080 monitor.....will this drain resources/slow render speeds in C4D/Octane?

Thanks!

Hi Dean,
no, you should not see any slow down in terms of speed, but your VRAM will be highly reduced by the big resolution of the 4k monitor.
The best way is always to have a dedicated GPU for display and system and one or more for Octane only, but I'm not able to suggest you a sigle slot GPU mac compatible with 4k support, sorry.
If you could use the 680 for display and add a newer and faster GPU for Octane, then it would be the best.

Definately use a dedicated card for display.. over here I got dual 4K and a 2560x1080 on top of them, when I use the primary card in Octane aswell the entire Windows UI becomes 2 fps.

Hi there,

I have triple monitor setup.. dual 2560x1440px (workspace) and one 4k (used for OctaneRender Viewport)...
each monitor is connected on a seperate GPU (Titans).
I always set GPU Render Priority Low, and no problems with monitor while rendering... can do other heavy tasks while rendering (i.e. Photoshop)

@Phantom, how do you measure your monitor fps (on multiple monitors)?

cheers

No measurement rappet, was just an estimate. But it becomes totally unusable, Octane just demands all of the performance and leaves zero for windows UI.

But not when settimg Render Priority low
