Viewport extremely laggy

Rhino Rhino for Windows
1

Hello,

after last update or two updates before (dont remember exactly, it is already some time though) I am not able to work with rhino on my laptop at all. After purchasing it was running just fine, also rhino 5 (trial) was running fine on this. The viewport is just laggy, if I am trying to rotate the scene it takes 30seconds until it updates. This is happening with default rhino empty document and also with my older documents, where is some geometry, really lightweight document is unusable. I am not sure what have happened, I have updated my gpu driver. I have tried all stuff written in other similar posts

  • disabling opengl
  • disabling plugins
    -…

in the left down corner of the viewport, there is written that the GPU is disabled for some unknown reason, I havent been able to find out where the option to turn it on is or why it is disabled at all.

here is my sys info>

Your GPU driver is very old. A recent driver from this year is available at Intel® Graphics Driver for Windows* [15.33]

@jesterking thank you for suggestion, intel updater says though, that the driver is up to date, if I try to install provided one, installation gives error that the driver is not suitable for my pc. also Rhino was running before update just fine, is there a way how to roll back?

ps. I also tried to reinstall, no luck.

Can you paste the entire output of the Rhino command _SystemInfo ?

You did download the correct installer for your OS version?

In this case I think the more likely scenario is that a Windows Update hosed your driver installation, your driver looks too old, newer are available, also for your GPU model.

well, if I use ‘intel driver and support assistant’ it also claims all drivers available are up to date.

rhino is still claiming it is not using gpu at all - what can I do to change this? (is the driver update the only solution?)

is there any way to roll back to previous release?

best,
mj

You may want to do a clean reinstall of your GPU drivers, just to make sure they are absolutely correct. There has been a pattern of Windows updates during October / November breaking drivers, hence my persistance on ensuring your drivers are up-to-date. The data you pasted shows your driver is from 2015…

Rolling back to older Rhino version means installing from older installer. I’m not sure where they are saved to (assuming you use the auto update feature of Rhino). @pascal, @John_Brock ?

@nathanletwory, @mjmjmj - the files are here:

C:\ProgramData\McNeel\McNeelUpdate\DownloadCache

You may have to poke around to find the installer you want.

Thanks, are the files there even if I did a clean reinstall of Rhino lately?
