Most "Windows accelerator" video cards were 2D-capable fixed-function processors that received 2D drawing commands and pixel data sent from the [[Central processing unit|CPU]], resulting in faster window drawing.<ref>{{Cite web|date=2019-01-07|title=Your computer's graphics card isn't just for gaming.

In the high-end professional market, at prices in the thousands of dollars, there were also coprocessor based video chipsets like the [[TMS34010|Texas Instrument TMS34020]] available, which allowed offloading of some of the processing from the CPU to the coprocessor's [[Graphics card|videocard]].<ref>{{Cite book
To make use of these accelerator or coprocessor based video cards, driver software for the specific video chipset was necessary.<ref>{{Cite web|last=III|first=Scott Fulton|title=Arm processors: Everything you need to know now|url=https://www.zdnet.com/article/arm-processors-everything-you-need-to-know-now/|access-date=2021-08-05|website=ZDNet|language=en}}</ref>
