Use CPU-based display driver instead of integrated graphics.
Use CPU-based display driver instead of integrated graphics.
CPU rendering Crysis remains an intriguing idea, though not yet practical. The simplest approach might involve controlling a screen. Could consumer processors handle such tasks today? What level of performance would be necessary? Testing would require rethinking the operating system interface entirely.
Yes the OS would need to support it, or run the OS virtualised where a GPU is emulated (though probably not the 3D functionality). But why would you want to? GPUs were invented for a reason, CPUs are incredibly inefficient at doing GPU tasks. If you're thinking using a CPU without an iGPU, there's no functionality to get a display output as that hardware is missing. The simple act of booting up expects at a bare minimum a VESA compatible GPU, in fact a modern UEFI BIOS may even need more than that. Once in the OS, there are USB display adapters that effectively ARE CPU driven, they're only fast enough for fairly basic use though.
The same logic applied when attempting to play Crysis. It’s likely someone is ready to create a compatible BIOS.
