Original Xbox One & 360 Games - Why aren't they rendered in 1080p?

Not all games change the resolution when becoming backwards compatiable

Kameo and Perfect Dark Zero were practically GameCube era games. They couldn't be THAT demanding.

I think the reason these games aren't rendered in 1080p is because enhanced started in 2017. RARE Replay re-released these games in 2015. By that time the original XBOX Ones were replaced by XBOX ONE X. They just chose not to support the original consoles with
enhancements for these games.

Hi,

You may not be aware of this, but making 360 and original Xbox games work on the Xbox One is not a simple process. These games were coded to work on different hardware to the Xbox One.

The Xbox 360 for example uses an IBM PowerPC processor architecture. This is totally different to the Xbox One. The 360 has more in common with the old Apple Power Macs before Apple made the jump to Intel in around 2005

To make Xbox 360 games work on the Xbox One, the BC team couldn't just make an emulator and run the games through that simply because the Xbox One has quite a week processor, it's simply isn't fast enough. They approached it from a different angle. The Xbox
One GPU is actually able to emulate the 360's graphics chip, but the processor is a different beast. To get around that they have converted or otherwise reverse engineered the 360 games to run them on the Xbox One. Turning otherwise 32-bit PPC coded games
into 64-bit X86 compatible Xbox One games.

The original Xbox is also different. Interestingly it shares the same processor architecture with the Xbox One in form of an X86 Intel Celeron 700Mhz processor, but its graphics chip was NVIDIA based.

So even though a game like Perfect Dark doesn't seem so demanding, it's a lot more complex than that. It's not like taking a PC game, putting it on a more powerful PC and pushing up the resolution.

Hello, it is probably because being emulated games the emulation can often require more hardware than you think in certain situations, if for example an upscaled game on xbox one would be fine, but in moments with too many enemies it would decrease
in framerates it would be better not to increase the resolution in the old xbox not to ruin the game.

[quote user="MiamiHeatFan77"]Is this true?[/quote]No, it's not true. The 360 support 1080p output.



You may have read that most games do not render internally at 1080p. They rely on the 360's scaler to scale the output to 1080p.[quote user="CPL Dom Caboose"]The only way to get the full 1080p experience is by using an HDMI cable to connect your XBOX 360
to your television.[/quote]The 360 supports 1080p in games over Component and VGA in addition to HDMI. There are some restrictions over Component for video, though not VGA.

The XBOX 360 is a much different experience when switching to 1080p

Not
especially. The Dashboard widgets aren't particular high resolution. Most games internally render at 720p or below.
