The new MV3 architecture reflects Google’s avowed desire to make browser extensions more performant, private, and secure. But the internet giant’s attempt to do so has been bitterly contested by makers of privacy-protecting and content-blocking extensions, who have argued that the Chocolate Factory’s new software architecture will lead to less effective privacy and content-filtering extensions.
For users of uBlock Origin, which runs on Manifest V2, “options” means using the less capable uBlock Origin Lite, which supports Manifest V3.
I’m guessing you don’t already use Linux? Just keep in mind that with a VM, the GPU has to be emulated (except for edge cases, like passing through a hardware GPU or going headless), which will heavilly impact performance. There is also the option of dipping your toe using a live USB stick (basically every distro has this as an option), but that has its own performance penalty due to running off of a USB stick.
I’d recommend actually installing it to try it out to get the full performance of your hardware, and to make sure that everything you have is compatible (most hardware is compatible out of the box)
