How can "View using CPU" result in better lines than "View using GPU" when my GPU has 3 times the RAM of my integrated Intel CPU graphics?

I refer to Adobe November 2017 post here: https://helpx.adobe.com/illustrator/kb/gpu-performance-errors-troubleshooting-workarounds.html

I have encountered two problems with working with my Illustrator artwork.

1. Rendered artwork appears jagged when in GPU Preview mode (View > View Using GPU) but NOT in CPU View Mode.

This is very concerning for me because I am using a newly acquired Adobe Recommended NVIDIA Quadro P1000. It is believed that GPU View mode should have superior performance to that of my CPU?

Furthermore, I chatted online with an official NVIDIA representative, last night,  and he did trouble shooting, and they ran diagnostics on my computer and have confirmed that my NVIDIA hardware and driver are up to date and running well. I also have a new computer with the latest 8^th Generation i7 processor at 3.2 Ghz.

Was I right in thinking (and buying) that my NVIDIA Quadro P1000 Graphics Card (3 gig RAM) ought to be better than my integrated Intel Graphics Card (1 GIG RAM)?

My thoughts are that I may have rendered my artwork in a way that may have made it appear jagged. But, still, "View using CPU" solves the problem anyway - no jagged lines (in other words excellent anti-aliasing). So I guess the "real problem" is that the performance of my Integrated Graphics Card is higher than my more powerful NVIDIA P1000!

Can this be? I've maxed out my NVIDIA Control Panel setting and have tried different combos and, still, View using CPU has  noticeably superior anti-aliasing!

I’m scared because when I move on to Adobe Premier Pro and After Effects, I really hope that my NVIDIA gets fully utilised then.

Note: I have NOT done Solution 2 on the site above, because the article was written on November 2, 2017 and my Adobe file names are newer and different (Adobe Illustrator 23). I don’t think it’ll help anyway as I am new to Illustrator and haven’t adjusted my preferences except for when Adobe recognized I have an NVIDIA graphics card. Anti-aliasing is ticked on. I suggest Adobe updates there Solution 2 instructions.

Adding more RAM doesn't make software better.  The word "performance" is not really applicable to this: that's about how fast it goes, not what the results look like, You seem to be concerned that the GPU isn't being used, but clearly it IS being used. Don't confuse speed with quality, or RAM with detail.

Oscar,

I believe it is time to ask Adobe, through a chat,

https://helpx.adobe.com/contact/support.html

I believe you know all or some of the following.

Graphics cards have been included in the system requirements:

Apart from an inadequate card, the issue can be caused by lack of driver updating, lack of proper recognition of the card by the computer, and whatnot (including rifts in the space time, moon, weather, and the fact that Illy sometimes moves in mysterious ways).

Here are a few more pages about GPU troubleshooting:

Hi Jacob,

Me's contacted Abode and am waiting for their opinion.

Thanks again.

You are welcome, Oscar.

I hope you will report your findings.

And sometimes of course it is caused because the new driver has new bugs. Troubleshooting drivers often includes trying old drivers, beta drivers and so forth. GPU is a pain, almost entirely because of driver bugs. Please do not give the mantra "the driver is up to date, it must be fine". At one time, every driver, no matter how terrible, was the most up to date.
