I wouldn't want to run any graphically intensive DOS applications either; a solution such as DOSbox is probably better there.
Historically, integrated solutions were often considered unfit to play 3D games or run graphically intensive programs but could run less intensive programs such as Adobe Flash.
One of the last racing simulations to be released for Nintendo 64, this graphically intensive title used custom microcode optimization and high polygon count modelling.
Underclocking a GPU will reduce performance, but this decrease will probably not be noticeable except in graphically intensive applications.
In general, the most memory hungry users are those who work with computer-aided design, electronic publishing, scientific modeling or other graphically intensive tasks.
I only encountered the scenario where it dropped other pages from memory when I loaded graphically intensive webpages, such as icanhascheezburger.com and cuteoverload.com.
These boards can also boost performance when editing video or other graphically intensive tasks.
Some are more scripting intensive, others more graphically intensive; some have complex layouts, others are simple.
For graphically intensive applications like Google Maps, this should result in better performance and an improved user experience.
The developers create the illusion of 3D by looping background textures-a graphically intensive technique for the Game Boy Advance.
