Why not? The original Doom didn't use a GPU renderer. It should be possible to do simple 3d stuff in today's computers without it.

- 1313ed01 1y agoEven Quake launched with software rendering. Not sure if the first release even had support for any hardware acceleration?
- flohofwoe 1y agoIIRC GLQuake was more like an experiment, only Quake II had proper GL support from the start.
- sfn42 1y agoThe original doom wasn't even proper 3d. It was a sort of 2,5d. And sure you can do 3d rendering on modern CPUs. It's just better on GPUs. Like thousands of times better.
- Flamingoat 1y agoThe main limitation of the engine is you couldn't have room over room. There is definitely three dimensions when playing the game.
- alxmdev 1y agoSomeone always points out how Doom wasn't "real 3D" like it's some sort of gotcha. Games are smoke and mirrors, it's all a 2D grid of pixels at the end.
- sfn42 1y agoWell yeah, a 2d grid of pixels also describes the result of rendering a 2d game. It matters how you arrive at that 2d grid of pixels, that's why you can't render Crysis on just a CPU. At least not in real time.
