My rhino is running slow in shaded mode. It freezes for a few seconds after every action - even just moving an object. This started happening not too long ago and I have no clue what it could be.
Well, you can run SystemInfo and post the results here. Check your video drivers is the first thing.

So yeah your video driver is a bit out of date, it needs to be kept up for the more advanced OpenGL usage in Rhino 6 to keep working along with Windows and Rhino updates. Also check that your Rhino and Windows are up-to-date.
is this something i can update or do i need to change it?
Updating the video driver? You just go to nvidia.com and download it there.
What SR of Rhino are you running? That would also be in the SystemInfo box.
Okay I will try that.
Is this it?:
Rhino 6 SR23 2020-2-24 (Rhino 6, 6.23.20055.13111, Git hash:master @ 8106edaa648ba209a8fc587f0f7fcccbaac09169
Okay your Rhino is pretty current, get your video drivers updated.
When you install the nVidia drivers, click on the Advanced option and choose a “Clean” install.
A clean install with reset any driver setting tweaks that may have been done.
Thanks, I updated the driver and restarted my computer, however, these freezes keep happening
What plug-ins do you have loaded?
SystemInfo includes that information as well.

In Rhino Options > Plug-ins, change the filter to Plug-ins that do not ship with Rhino.
Disable all of them.
Close Rhino and restart.
Does this help with the slowness you described?
Also, how many monitors are you running, and at what resolution?
sorry, what do you mean that do not “ship” with rhino?
two monitors - not sure how to figure out the resolution
Right-mouse click on the Windows Desktop
Click Display Settings
Find the Display resolution
Do this on both monitors
One is 2560 x 1600, second is 3840 x 2160
Also, the plug in showing under that is “thea render” which is the renderer i am using currently. Would that disable it?
Yes.
This is a test to try to determine what the problem is.
After disabling Thea and restarting Rhino, does that fix the performance?
If yes, then turn it back on and restart again.
Does the slowness come back, if yes, then you have isolated the cause.
