My Asus Vivobook Pro 15 OLED doesn't run Illustrator 3D objects and Premier Pro crashes quickly

What kind of graphics accelerator card is installed in your notebook computer? Does it have a discrete graphics accelerator board, such as a NVidia RTX or AMD Radeon GPU? The discrete boards typically have their own separate pool of faster GDDR RAM. Or does your notebook have an integrated graphics chipset, such as an Intel "Iris" chipset?

In my humble opinion, 16GB of RAM is really the minimal amount anyone can get away with using these days even if they have a good dedicated graphics card installed in the computer. That's with using creative software such as Adobe's applications. A cheaper integrated graphics chip solution will siphon away some of that system RAM for its own purposes and just slow down the computer system further. Apple notebooks might be a bit better at handling the balance on this than Windows notebooks. But, still, I wouldn't buy a new notebook today with anything less than 32GB of RAM. Some but not all Windows notebooks have RAM modules that are removable and therefore upgradeable. If you're lucky enough you might be able to swap out the 16GB modules in your notebook for a 32GB or 64GB package. But if the RAM is soldered onto the motherboard (like it is for all Apple notebooks) then you're stuck with the 16GB you have. I have a very intense dislike for soldered on RAM. I will not buy a computer that has that garbage. If a decision was up to me I would have soldered-on RAM banned by law.
