No responses, but I'm sure we have users out there with K4000's. Perhaps ones that only visit the forum occasionally.
Can't help directly, but a few comments.
In comparison the K4000 is similar in Passmarks to the K5000M, so in our Benchmarks that would equate roughly to something like a GTX 560. You can view the Lumion Benchmarks here: Guest Forum Users - Benchmark Results (v3.1.1+)
. No K4000 in chart, so closest is the 4000 or K5000M.
As mentioned elsewhere, preference is for a general graphics card (GTX or Radeon) if possible. Or maybe the option if need Quadro for CAD work, then a mix including a GTX assigned for Lumion. Something like a GTX 970 lesser cost version is probably 2.5 times performance and capacity of the GTX 560 mentioned above.
I have used a GTX 560 then GTX 660 and loaded some very heavy user scenes. I think two cases, the modelling complexity (large number of highly detailed buildings, but only really needed the one), and details in scene were so large it would not load. Other than that, things loaded, just got slow in Build Mode
or much longer to render.
Noting also, that there are things that can be done to manage scenes that demand more of the hardware, or require longer times to render. So it's not an open/shut case of xyz hardware only being able to handle a particular setup for a scene.
Added to that of course, find hardware that provides 'enough' spare capacity.
