I see a lot of examples and tutorials for 3D engines like Unity3D, UDK, Source etc. They all seem to be under the assumption that you are making a game for current(ish) hardware.
I would like some tips or tutorials on how to develop a game using UDK, Unity3D or any other modern game engine while targeting what might be considered ancient hardware.
Hardware specs might be as low as
- 1GHz-1.8GHz single core CPU
- 8MB-64MB Video chip
- 512MB-1GB RAM
Thinking along the lines of older laptops or old business class machines that might have, at most, an Intel GMA900 chip or a ATI Radeon 9000 chip onboard.
