Hello, I would like to ask if this is an issue becouse of an incompatible graphic card, or becouse I have to do some checks on configuration.
I have a new Radeon RX 580 with ryzen 7 1700 cpu, and my Lapton Yoga 730 with intel UHD 620 integrated graphic card is performing way better than my desktop pc. Can’t tell the fps, but with the desktop pc I can only work switching off complex layers. the model I used for comparisson is a mesh imported from sketchup, so possibly is a bad geometry that makes the graphic card to fail.
if the problem is the graphic card im going to return it.

Thanks for your fast reply. It’s Rhino 6.12.18349.12551
I’m not familiar with the concept of cycles. Not using raytracying or rendering, only shaded viewport.
Anyway, I checked the options to see if there is something i was missing, and that dialog is rendered a bit weird.
you could use the command _Testmaxspeed
but for a fair comparison you should make sure all settings are teh same, same viewport resolution (use a floating viewport), maybe start from a namedView, same geometry and mesh settings etc
you could also use holomark 2 for comparing the two systems:

thanks. Nice!
Here is the comparisson… it sucks…
Same resolution. lower AA on desktop.
Desktop radeon 580RX: Time to regen viewport 100 times = 15.97 seconds. (6.26 FPS)
Tiny little laptop: Time to regen viewport 100 times = 8.59 seconds (11.FPS)
then there must be something wrong of course. the RX580 should be may times faster.
if you upload the file you tested with, I can check what result I getbwith my RX580.
I have much better results. in the screenshot you can see that I used a floating viewport with a resolution of 1280x960. wireframe, shaded and arctic all have very high fps:
oh sorry! i left the detailed layer turned off!
please, if its not much of o problem, turn on both layers named “edificios” the other one is nested inside
in the evening I can test the same on another system with a GTX1060.
when you compare you have to make sure you use a floating viewport and the same resolution. maybe one of the systems uses a 4K / high dpi monitor? or windows scaling? that could influence the results as well i think.
regarding the raw compute power the GPU is quite capable and of course many times more powerful that any intel iGPU. but in the end this comes down to optimization. if most of the mcneel userbase has intel or nvidia GPUs then mcneel is probably focusing on optimizing for those and care less about the GPUs used by a minority.
So maybe a good option is to return the graphic card, and change it for a nvidia model like gtx 1060?, it is the same value right now. I would wait for your answer! thanks a lot! thanks a lot for trying on that one
But its strange how much diferent fps we have, as we both have this card. could be the processor ryzen 7, 1700?
let me first see what the results are on my system with the GTX1060, when I get home in the evening.
my system has the newer Ryzen 7 2700X, so our systems are very similar. maybe it has something to do with the lower vram of your card. yours has 4GB, mine has 8GB. and the mode is rather large. maybe you should first try to uninstall and reinstall the drivers. also reinstalling rhino? I don’t really know.
subjectively I have to say that the model behaves quite well on my system. the geometry looks to be imported to rhino from somewhere else, right? it is large but overall quite simple geometry. if you would rebuild this in rhino, the whole model would behave much better / be more efficient i think. I also see lots of missed opportunities where you could use blocks.
your ~6fps really seem to be too low for shaded display mode. even if I maximize my viewport (2560x1440 monitor), I get around 20fps in shaded. even if i turn on all the layers and max the viewport, I still get over 17fps.
also all the curves make the viewport a bit slower. if i select all curves with _SelCrv and _Hide then I go from 17 to 22 fps.
